📚 Case Study Practical Exercises for A-Level Cambridge Geography | A-Level Cambridge 地理：案例分析实战演练

Case study questions lie at the very heart of A-Level Cambridge Geography. They demand not only factual recall but the ability to apply concepts, analyse interconnections, and evaluate management strategies within real-world contexts. This article provides ten structured practical exercises, each built around a realistic case scenario. For every exercise you will find a concise background, a set of indicative questions, and a model-answer framework that demonstrates how to structure high-scoring responses. Use these exercises to sharpen your analytical skills and build confidence for Paper 1, Paper 2 and Paper 3.

案例分析题是剑桥 A-Level 地理的核心所在。它不仅考查知识记忆，更要求学生能够在真实情境中运用概念、分析联系并评价管理策略。本文提供十个结构化的实战练习，每个都围绕一个真实的案例场景构建。每个练习包含简要背景、一组指引性问题以及示范答案框架，用以展示如何组织高分回答。通过这些练习，你可以磨炼分析能力，树立应对卷一、卷二和卷三考试的信心。

1. Mastering the Case Study Approach | 掌握案例分析的方法

Before diving into the exercises, it is essential to know what examiners look for. A top-tier answer moves beyond description to offer analysis, use precise place-specific detail, consider scale and stakeholder perspectives, and always include a critical evaluation. Start by deconstructing the question command words: ‘explain’ requires causal reasoning, ‘assess’ demands balanced judgement, and ‘to what extent’ invites a nuanced conclusion.

在进入练习之前，必须了解考官看重什么。高分的答案超越了单纯描述，要进行深入分析、使用精确的地域细节、考虑尺度与利益相关方的视角，并始终包含批判性评价。首先，要拆解问题中的指令词：“解释”要求因果推理，“评估”需要平衡的判断，“在多大程度上”则引出有细微差别的结论。

Effective case study revision moves away from memorising entire stories. Instead, build a flexible mental framework organised around location, causes, consequences, management and evaluation. Practice pulling relevant details from this framework to answer a variety of question angles. The exercises below are designed to train exactly that skill.

高效的案例分析复习不应死记硬背整篇故事。相反，你应当构建一个灵活的心理框架，围绕区位、成因、后果、管理措施和评价进行组织。练习从这个框架中提取相关细节来回答不同角度的问题。下面的练习正是为了训练这一技能。

2. River Flooding: The Somerset Levels, UK | 河流洪水：英国萨默塞特平原

The Somerset Levels are a low-lying coastal plain in South West England. In the winter of 2013–14, successive Atlantic storms brought unprecedented rainfall, saturating the clay soils and overwhelming the River Parrett and its tributaries. Prolonged flooding affected over 600 homes, cut off villages, and submerged thousands of hectares of farmland. The event sparked a national debate about dredging, floodplain management and climate adaptation.

萨默塞特平原是英格兰西南部一片低洼的滨海平原。2013-14 年冬季，连续的大西洋风暴带来创纪录的降雨，使黏土土壤饱和，帕雷特河及其支流失控泛滥。持续洪水影响了 600 多户住宅，切断了村庄通道，淹没了数千公顷农田。这次事件引发了全国范围内关于河道疏浚、河漫滩管理与气候适应的争论。

Question: Assess the relative importance of physical and human factors in causing the severe flooding on the Somerset Levels.

问题：评估在造成萨默塞特平原严重洪水中，自然因素与人为因素的相对重要性。

Model response guide: Begin by describing the physical triggers — prolonged intense rainfall, saturated soils, low relief and a high tidal range slowing river discharge. Then introduce human factors: reduced dredging of the River Parrett, expansion of built-up areas on the floodplain, and historical wetland drainage for agriculture. Use a balanced paragraph to weigh the evidence, concluding that while the rainfall magnitude was extreme, the severity of impact was significantly amplified by long-term management decisions.

示范回答指南：首先描述自然触发因素——长时间强降雨、土壤饱和、地势低平以及高潮差减缓了河流排泄。然后引入人为因素：帕雷特河疏浚减少、河漫滩上建设用地的扩张以及历史上为农业进行的湿地排水。用一个平衡段落实证考量，给出结论：虽然降雨量极大，但灾害的严重程度因长期的管理决策而被显著放大。

3. International Migration: Mexico to the USA | 国际人口迁移：墨西哥至美国

The US-Mexico migration corridor is one of the world’s most significant. Historically, push factors in Mexico — limited rural employment, low wages and rapid population growth — combined with pull factors in the USA — high demand for low-skilled labour in agriculture, construction and services — to drive millions northwards. Migrant remittances became a vital part of Mexico’s economy, yet the movement also generated political tension and challenges for border communities.

美墨迁移走廊是世界上最重要的迁移通道之一。历史上，墨西哥的推力因素——农村就业有限、低工资和人口快速增长——与美国的拉力因素——农业、建筑业和服务业对低技能劳动力的高需求——结合，驱使数百万人北上。移民汇款成为墨西哥经济的重要组成部分，但这一迁移也引发了政治紧张和边境社区的挑战。

Question: Explain the socio-economic impacts of Mexico-USA migration on both source and host countries.

问题：解释墨西哥—美国迁移对来源国和接收国的社会经济影响。

Model response guide: For Mexico, highlight positives such as remittances reducing poverty, relief of underemployment, and skills transfer when migrants return; balance with negatives including family separation, loss of working-age population, and dependency on external income. For the USA, discuss the filling of labour gaps, cultural diversity and downward pressure on wages for low-skilled domestic workers, alongside fiscal costs of public services. Always anchor arguments in named places and data where possible, such as the states of Jalisco or California.

示范回答指南：对墨西哥，强调汇款减少贫困、缓解就业不足和返乡移民带回技能等积极方面；同时平衡以家庭分离、劳动年龄人口流失以及对外部收入的依赖等消极方面。对美国，讨论填补劳动力缺口、文化多样性，以及对国内低技能工人的工资下行压力，同时提及公共服务的财政成本。回答中要尽可能用具体地点与数据支撑论点，如哈利斯科州或加利福尼亚州。

4. Urban Regeneration: King’s Cross, London | 城市更新：伦敦国王十字区

Once a derelict industrial and railway land site in inner London, the King’s Cross redevelopment is now a flagship of brownfield regeneration. The 27-hectare project, led by a private-sector partnership, delivered new offices, homes, public squares and the Granary Square cultural quarter. Sustainability was embedded through a combined heat and power plant, green roofs, and retention of historic gasholders as parkland features.

曾经是伦敦内城一片废弃的工业和铁路用地，国王十字区再开发如今已成为棕地更新的旗舰项目。这个占地27公顷的项目由私营合作方主导，提供了新办公室、住宅、公共广场和谷仓广场文化区。通过冷热电联产站、绿化屋顶以及将历史煤气罐保留为公园景观，项目深度融入了可持续设计。

Question: Evaluate the success of the King’s Cross regeneration in meeting the needs of different stakeholder groups.

问题：评价国王十字区更新在满足不同利益相关群体需求方面的成功程度。

Model response guide: Identify key stakeholders: investors, local residents, businesses, commuters, and the local authority. For each, weigh benefits (e.g. profit, job creation, improved public realm, enhanced transport links) against costs (e.g. gentrification, displacement of lower-income groups, loss of industrial heritage for some). Conclude with a judgement: the project is a commercial and environmental success but has been criticised for failing to provide sufficient truly affordable housing, reflecting typical tensions in market-led regeneration.

示范回答指南：识别关键利益相关方：投资者、当地居民、企业、通勤者和地方政府。对每一方，权衡收益（如利润、就业创造、公共空间改善、交通升级）与成本（如绅士化、低收入群体外迁、部分工业遗产的丧失）。评价性结论：该项目在商业和环境上是成功的，但被批评未能提供足够真正可负担的住房，这反映了市场主导型更新的典型矛盾。

5. Coastal Erosion: Holderness Coast, UK | 海岸侵蚀：英国霍尔德内斯海岸

The Holderness coast in East Yorkshire retreats at one of the fastest rates in Europe, averaging 1.8 metres per year. The cliffs are composed of soft boulder clay, vulnerable to wave attack from the North Sea. The village of Mappleton has been protected by a rock armour revetment since 1991, but neighbouring areas, such as Great Cowden, have suffered accelerated erosion due to sediment starvation downstream.

东约克郡的霍尔德内斯海岸是欧洲侵蚀速率最快的海岸之一，平均每年后退1.8米。悬崖由软质漂砾土构成，极易遭受北海海浪的侵蚀。自1991年起，马普尔顿村用岩石护坡进行了防护，但下游的大考登等邻近地区因沉积物截留而遭受了加速侵蚀。

Question: Using the Holderness coast, discuss the conflicts that can arise from coastal management decisions.

问题：以霍尔德内斯海岸为例，讨论海岸管理决策可能引发的冲突。

Model response guide: Outline the conflict between protection and economic value: Mappleton’s defence was justified by the B1242 road, but it transferred erosion to farmland further south. Introduce the social conflict between property owners in protected areas and those losing land. Add the environmental conflict: interrupting natural sediment transport affects habitat downdrift. Bring in the SMP (Shoreline Management Plan) held line versus no active intervention policies. Conclude that coastal management is rarely win-win; trade-offs are geographically and socially unequal.

示范回答指南：概述防护与经济价值之间的冲突：保护马普尔顿是为了保住B1242公路，但这将侵蚀转移到更南方的农田。引入受防护区业主与失去土地者之间的社会冲突。补充环境冲突：打断自然沉积输送影响了下游的栖息地。纳入岸线管理计划中“维持防线”与“不主动干预”的政策对比。结论是海岸管理很少能实现双赢；权衡在空间和社会上是不平等的。

6. Tectonic Hazard: Gorkha Earthquake, Nepal, 2015 | 构造灾害：2015年尼泊尔廓尔喀地震

On 25 April 2015, a magnitude 7.8 earthquake struck near Gorkha, Nepal. The shallow focus (15 km) and the collision of the Indian and Eurasian plates generated intense shaking. Over 9,000 people died, hundreds of thousands of buildings collapsed, including UNESCO World Heritage sites in the Kathmandu Valley. The event tested Nepal’s limited emergency response capacity and exposed the vulnerability of an LIDC to a high-magnitude seismic hazard.

2015年4月25日，尼泊尔廓尔喀附近发生7.8级地震。震源浅（15公里），印度板块与欧亚板块碰撞产生了剧烈震动。超过9000人遇难，数十万栋建筑物倒塌，包括加德满都谷地的联合国教科文组织世界遗产。这次事件考验了尼泊尔有限的应急响应能力，暴露了低收入发展中国家面对高强度地震灾害的脆弱性。

Question: Evaluate the reasons for the scale of the disaster in Nepal, considering both the nature of the hazard and the vulnerability of the population.

问题：评估尼泊尔灾难规模的成因，同时考虑灾害特性与人口的脆弱性。

Model response guide: Hazard side: high magnitude, shallow focus, occurrence in a densely populated valley with liquefaction-prone river sediments. Vulnerability side: widespread poverty, poor building standards (non-engineered masonry), lack of enforcement of seismic codes, deforestation leading to landslide risk, and a weak state unable to coordinate rapid response. Link to the pressure and release model: root causes such as political instability and limited access to education increased dynamic pressures. A strong conclusion must weigh hazard against vulnerability, likely arguing that vulnerability was the principal amplifier of loss.

示范回答指南：灾害方面：震级高、震源浅，发生在人口密集的山谷，河流沉积物易液化。脆弱性方面：普遍贫困、建筑标准差（非工程砌体）、缺少抗震规范执行、森林砍伐增加滑坡风险、政府无力协调快速响应。结合压力与释放模型：政治不稳定和受教育机会有限等深层根源增加了动态压力。一个有力的结论必须权衡灾害与脆弱性，可能主张脆弱性是放大损失的主要因素。

7. Tropical Rainforest Management: Amazonas, Brazil | 热带雨林管理：巴西亚马孙

The Brazilian Amazon, the largest continuous tropical rainforest on Earth, has lost around 20% of its original cover, largely due to cattle ranching, soybean cultivation, and illegal logging. Conservation strategies include protected areas (e.g. Jaú National Park), the Fundo Amazônia supported by international donors, and satellite-based monitoring systems such as PRODES and DETER. However, deforestation rates surged again in recent years under political pressure to open land for economic development.

巴西亚马孙是世界上最大的连片热带雨林，已失去约20%的原始覆盖，主要原因是养牛、大豆种植和非法采伐。保护策略包括设立保护区（如雅乌国家公园）、由国际捐助支持的亚马孙基金，以及PRODES和DETER等卫星监测系统。然而，近年来在开放土地用于经济发展的政治压力下，森林砍伐率再次飙升。

Question: Assess the effectiveness of different strategies used to manage the Brazilian Amazon rainforest.

问题：评估用于管理巴西亚马孙热带雨林的不同策略的有效性。

Model response guide: Create a table of strategies and evaluate each. Command-and-control (protected areas, fines): moderately effective when enforced, but limited by corruption and understaffing. Market-based (certification, REDD+ payments): offer economic alternatives but struggle with leakage and land tenure issues. Community-based management: successful in extractive reserves where local people gain rights. Technology (real-time deforestation alerts): shows high potential but requires political will to act on data. Overall evaluation: strategies work best when combined and when national governance supports conservation.

示范回答指南：制作一个策略评估表。指令控制型（保护区、罚款）：在得到执行时效果中等，但受腐败和人员不足的限制。市场型（认证、REDD+支付）：提供经济替代方案，但面临泄漏和土地权属问题。社区管理型：在民众获得权利的采掘保护区较为成功。技术型（实时毁林警报）：显示出高潜力，但需要政治意愿根据数据采取行动。总体评价：当多种策略结合且国家治理支持保护时，效果最佳。

8. Urban Air Quality: Beijing, China | 城市空气质量：中国北京

Beijing’s rapid industrialisation and vehicle boom made it notorious for hazardous smog episodes, with PM2.5 levels peaking above 500 μg/m³ in severe pollution events. The government’s ‘Clean Air Action Plan’ (2013–2017) enforced coal-to-gas switching, vehicle restrictions, relocation of heavy industry, and massive expansion of public transport. By 2020, annual average PM2.5 concentrations had fallen by over 40%, though still above WHO guidelines.

快速的工业化和汽车激增使北京因危险烟雾事件而闻名，严重污染时PM2.5浓度峰值超过500微克/立方米。政府的《大气污染防治行动计划》（2013–2017年）强制推行煤改气、车辆限行、重工业迁出以及公共交通的大规模扩展。到2020年，年均PM2.5浓度下降了40%以上，但仍高于世卫组织指导值。

Question: Evaluate the social and economic impacts of Beijing’s air pollution policies.

问题：评价北京空气污染治理政策的社会和经济影响。

Model response guide: Economic positives: long-term healthcare savings, growth in clean energy industries, improved productivity. Economic negatives: short-term costs for factories and displaced workers, higher heating costs for low-income households during fuel switching. Social positives: improved life expectancy, fewer school closures, enhanced civic pride. Social negatives: uneven enforcement, regional disparities (pollution relocating to neighbouring provinces), and limited public participation in decision-making. A balanced conclusion might recognise the measurable health gains while pointing out that truly sustainable air quality requires regional cooperation and not just capital-city fixes.

示范回答指南：经济正面：长期医疗支出节省、清洁能源产业增长、生产率提高。经济负面：工厂和失业工人的短期成本、燃料转换期间低收入家庭供暖费用增加。社会正面：预期寿命延长、学校停课减少、公民自豪感提升。社会负面：执法不均、地区差异（污染转移到周边省份）、决策中公众参与有限。一个平衡的结论可能承认可衡量的健康收益，同时指出真正可持续的空气质量需要区域合作，而非仅靠首都的单点治理。

9. Food Production: Intensive Rice Farming in the Mekong Delta | 粮食生产：湄公河三角洲的集约化水稻种植

The Mekong Delta in Vietnam is one of the world’s most productive rice-growing regions, supplying about 50% of the country’s rice output and a large share of global exports. The ‘rice bowl’ depends on high-yielding varieties, triple-cropping and heavy use of agrochemicals. However, upstream dam construction, saline intrusion from sea-level rise, and soil degradation now threaten the long-term sustainability of this intensive system.

越南的湄公河三角洲是全球最高产的水稻种植区之一，供应全国约50%的稻米和全球大米出口的很大份额。这个“粮仓”依赖高产品种、三季连作和大量使用农用化学品。然而，上游筑坝、海平面上升引起的咸潮入侵以及土壤退化，如今正威胁着这一集约化系统的长期可持续性。

Question: Discuss the factors that have enabled high agricultural productivity in the Mekong Delta, and the challenges that now limit its sustainability.

问题：讨论使湄公河三角洲获得高农业生产力的因素，以及如今限制其可持续性的挑战。

Model response guide: Enabling factors: fertile alluvial soils replenished by annual floods, abundant water for irrigation, government support through price subsidies and infrastructure, adoption of Green Revolution technologies, and strong export markets. Challenges: reduced sediment supply due to upstream dams, saltwater intrusion rising up distributaries, over-reliance on chemical inputs causing eutrophication, and land subsidence from groundwater extraction. Conclude that productivity was built on finite natural capital; without systemic change to integrated water-resource management, the delta’s food production capacity will decline.

示范回答指南：驱动因素：每年洪水补充的肥沃冲积土、充足的灌溉水源、政府通过价格补贴和基础设施提供的支持、绿色革命技术的采用，以及强大的出口市场。挑战：上游水坝减少了沉积物供应、咸潮沿分流河道上溯、过度依赖化学投入导致富营养化，以及地下水抽取引起的地面沉降。结论是生产力建立在有限自然资本之上；若不系统转向水资源综合管理，三角洲的粮食生产能力将会下降。

10. Tourism Development: Mallorca, Spain | 旅游业发展：西班牙马略卡岛

Mallorca is a classic mass tourism destination, having evolved from a quiet Mediterranean island in the 1960s to an international holiday hub receiving over 12 million visitors annually. The tourism life-cycle model (Butler) tracks its journey from exploration to stagnation. In response to overcrowding, the local government has introduced sustainability measures: a tourism tax, limits on new hotel beds, and promotion of rural and cultural tourism to diversify the offer.

马略卡岛是经典的大众旅游目的地，从上世纪60年代宁静的地中海岛屿发展成为国际度假枢纽，年接待游客超过1200万人次。旅游地生命周期模型（巴特勒）描绘了它从探索期走向停滞期的轨迹。为应对过度拥挤，地方政府推出了可持续措施：旅游税、限制新增酒店床位以及推广乡村和文化旅游以实现产品多样化。

Question: With reference to Butler’s model, evaluate the strategies Mallorca has used to manage the negative impacts of mass tourism.

问题：参照巴特勒模型，评价马略卡岛为管理大众旅游负面影响所采取的策略。

Model response guide: Locate Mallorca in the model (consolidation-stagnation phase). Negative impacts include seasonal water shortages, beach degradation, waste pressure, and resident resentment. Strategies: eco-tax used to fund environmental restoration; moratorium on bed expansion aims to cap tourist numbers; product diversification (hiking, gastronomy) targets higher-spending visitors. Evaluation: these strategies have slowed decline and improved environmental quality but have not fundamentally decoupled the economy from high visitor volumes. Rejuvenation likely requires more radical measures, such as prioritising quality over quantity and engaging local communities in planning.

示范回答指南：将马略卡岛定位于模型中的巩固-停滞阶段。负面影响包括季节性缺水、海滩退化、废弃物压力以及居民不满。策略：生态税用于资助环境修复；床位扩张禁令旨在限制游客数量；产品多样化（徒步、美食）瞄准高消费游客。评价：这些策略减缓了衰退，改善了环境质量，但并未从根本上使经济脱离对高访客量的依赖。要实现复兴，可能需要更根本性的措施，例如优先质量而非数量，并让当地社区参与规划。

11. Water Scarcity: Aral Sea Basin, Central Asia | 水资源短缺：中亚咸海流域

The Aral Sea, once the fourth-largest inland water body, has shrunk to less than 10% of its original area. Soviet-era decisions to divert the Amu Darya and Syr Darya rivers for cotton irrigation in Uzbekistan and Turkmenistan turned a vibrant lake into a salt desert. The ecological collapse led to a public health catastrophe, with dust storms carrying toxic salts and pesticides, and the loss of the fishing industry.

咸海曾是世界第四大内陆水体，如今已萎缩至原先面积的10%以下。苏联时期决定将阿姆河与锡尔河的河水引用于乌兹别克斯坦和土库曼斯坦的棉花灌溉，使得一片充满活力的湖泊变成了盐漠。生态崩溃导致了公共卫生灾难，沙尘暴携带有毒盐分和农药，渔业也由此消失。

Question: Analyse the causes and consequences of the Aral Sea shrinkage, and evaluate the possibilities for restoration.

问题：分析咸海萎缩的原因和后果，并评价恢复的可能性。

Model response guide: Causes: large-scale irrigation schemes, inefficient water use (open canals), and lack of transboundary agreement. Consequences: detail environmental (increased salinity, altered microclimate), economic (loss of fishing sector), health (respiratory diseases, infant mortality) and social (forced migration). Restoration: the Kok-Aral Dam in Kazakhstan has partially restored the Small Aral Sea, improving local fisheries. Full restoration of the Large Aral Sea is unlikely due to entrenched agricultural economies and water deficits. A realistic path is managed retreat and adaptation, alongside improved water efficiency and diversification of livelihoods.

示范回答指南：原因：大规模灌溉工程、水资源利用效率低（开放式渠道）以及缺少跨界协议。后果：详述环境（盐度上升、微气候改变）、经济（渔业损失）、健康（呼吸道疾病、婴儿死亡率）和社会（被迫迁移）等方面。恢复：哈萨克斯坦的科克-咸海大坝已使小咸海部分恢复，改善了当地渔业。由于根深蒂固的农业经济和水资源赤字，大咸海的全面恢复希望渺茫。现实路径是有管理的退却与适应，同时提高用水效率和实现生计多样化。

12. Global Development Gap: Rwanda | 全球发展差距：卢旺达

Rwanda’s post-genocide development trajectory is often cited as a development success story. With a strong focus on governance, gender equality, and ICT, the country has achieved rapid GDP growth and significant poverty reduction. However, it remains a LIDC with a high population density, limited natural resources, and a reliance on subsistence agriculture and foreign aid. The contrast between Kigali’s modern skyline and rural poverty illustrates the unevenness of development.

卢旺达种族灭绝后的发展轨迹常被引述为发展成功的范例。凭借对治理、性别平等和信息通信技术的高度重视，该国实现了快速的GDP增长和显著的减贫。然而，它仍是一个低收入发展中国家，拥有高人口密度、有限的自然资源，依赖自给农业和外援。基加利的现代天际线与农村贫困之间的对比，反映了发展的不均衡。

Question: Assess the extent to which Rwanda’s development strategy can be considered a model for other LIDCs.

问题：评估卢旺达的发展战略在多大程度上可被视为其他低收入发展中国家的典范。

Model response guide: Strengths: visionary leadership, strong anti-corruption drive, high parliamentary representation of women (over 60%), investment in education and Vision 2020/2050 planning, successful health insurance scheme (Mutuelles de Santé). Limitations: aid dependency (budget support still substantial), constrained political freedoms, land scarcity, and vulnerability to commodity price shocks. Model? It is inspirational in human development indicators and political stability, but the centralised, top-down approach may not transfer easily to societies with different political cultures. Conclude that elements such as community-based health finance and gender quotas are transferable, while the overall model requires adaptation to local contexts.

示范回答指南：优势：富有远见的领导层、强有力的反腐行动、女性高达60%以上的议会代表率、对教育的投资和《2020愿景》/《2050愿景》规划、成功的健康保险计划（Mutuelles de Santé）。局限：对外援依赖（预算支持仍很大）、政治自由受限、土地稀缺、易受商品价格冲击影响。是否典范？它在人类发展指标和政治稳定方面鼓舞人心，但集中式的自上而下方法可能不易移植到不同政治文化的社会。结论：社区为基础的卫生融资和性别配额等元素是可转移的，而整体模式需要根据当地情况调整。
