1. Tectonic Processes and Hazards | 板块构造与地质灾害

Plate tectonics explains the global distribution of earthquakes, volcanoes and tsunamis. The Earth’s lithosphere is divided into major and minor plates that move by convection currents, slab pull and ridge push.

板块构造学说解释了地震、火山与海啸的全球分布。地球岩石圈被划分为大、小板块，其运动由地幔对流、板片拖曳力和洋脊推力驱动。

Constructive boundaries (e.g. Mid-Atlantic Ridge) generate basaltic lava and shallow earthquakes; destructive boundaries (e.g. Nazca–South America) produce explosive volcanism and deep-focus earthquakes; conservative boundaries (e.g. San Andreas Fault) cause shallow, powerful earthquakes with no volcanism.

建设型边界（如大西洋中脊）产生玄武岩浆与浅源地震；破坏型边界（如纳斯卡板块与南美板块）引发爆发式火山活动和深源地震；守恒型边界（如圣安德烈亚斯断层）造成强烈的浅源地震，无火山活动。

The disaster risk equation Risk = Hazard × Vulnerability / Capacity to cope underpins the Pressure and Release (PAR) model. Governance, economic development and education influence vulnerability and resilience.

灾害风险方程 风险 = 灾害 × 脆弱性 / 应对能力 是压力与释放模型的基础。治理水平、经济发展与教育影响着脆弱性和恢复力。

Hazard management follows the Park Model (pre-disaster relief, rehabilitation, reconstruction) and the Hazard Management Cycle (mitigation, preparedness, response, recovery). Case studies such as the 2011 Tōhoku earthquake illustrate multiple hazards and cascading impacts.

灾害管理遵循帕克模型（灾前救济、恢复、重建）以及灾害管理循环（减轻、准备、响应、恢复）。2011年日本东北地震等案例展示了多重灾害及其连锁影响。

2. Coastal Landscapes and Change | 海岸地貌与演变

Coastal systems are driven by wave energy, tides, currents and wind. Littoral cells operate as sediment-sharing units with sources, transfer zones and sinks.

海岸系统受波浪能量、潮汐、海流和风驱动。沿岸输沙单元作为沉积物共享系统，包含物源区、输送带和沉积汇。

Erosional landforms include cliffs, wave-cut platforms, caves, arches, stacks and stumps. These develop on discordant and concordant coastlines, forming features such as the Dorset coast (Lulworth Cove, Durdle Door).

侵蚀地貌包括海蚀崖、海蚀平台、海蚀洞、海蚀拱、海蚀柱和海蚀残丘。它们在顺向与逆向海岸上发育，形成多塞特海岸的卢尔沃斯湾、杜德尔门等景观。

Depositional landforms are beaches, spits, bars, tombolos and salt marshes. Longshore drift and constructive waves build these features, especially in low-energy environments.

沉积地貌包括海滩、沙嘴、沙坝、连岛沙洲和盐沼。沿岸漂移与建设性波浪在低能环境中塑造了这些地貌。

Coastal management uses hard engineering (groynes, sea walls) and soft engineering (beach nourishment, managed retreat). Shoreline Management Plans (SMPs) set policies for defend, retreat or adapt over the next 100 years.

海岸管理采用硬工程（丁坝、海堤）与软工程（海滩补沙、管理性后退）措施。海岸线管理计划为未来百年制定了防护、后退或适应策略。

3. Water Cycle and Water Insecurity | 水循环与水资源不安全

The global hydrological cycle circulates water between stores (oceans, ice sheets, groundwater, atmosphere) via fluxes: precipitation, evaporation, transpiration, runoff and percolation. Drainage basin water balance is expressed as:

全球水循环通过降水、蒸发、蒸腾、径流和下渗等通量，在海洋、冰盖、地下水、大气等储库间循环。流域水量平衡可表示为：

P = Q + E + ΔS

where P is precipitation, Q discharge, E evapotranspiration and ΔS change in storage.

式中 P 为降水量，Q 为径流量，E 为蒸散发量，ΔS 为蓄水量变化。

Physical factors (climate, geology, relief) and human factors (abstraction, deforestation, urbanisation) modify the cycle. Rising water demand leads to water stress when annual supply drops below 1,700 m³ per person.

自然因素（气候、地质、地形）与人文因素（抽水、毁林、城市化）改变水循环。当人均年供水量低于1700立方米时，用水需求上升将引发水压力。

Water insecurity leads to conflicts and food shortages. Trans-boundary rivers (Nile, Mekong) and virtual water trade add geopolitical complexity. Sustainable management includes integrated water resource management (IWRM) and desalination.

水资源不安全导致冲突与粮食短缺。跨界河流（尼罗河、湄公河）和虚拟水贸易增加了地缘政治复杂性。可持续管理包括水资源综合管理和海水淡化。

4. Carbon Cycle and Energy Insecurity | 碳循环与能源不安全

The carbon cycle moves carbon between the lithosphere, hydrosphere, biosphere and atmosphere. Stores are measured in petagrams of carbon (PgC); geological stores (sedimentary rocks, fossil fuels) are orders of magnitude larger than pedosphere and atmosphere stores.

碳循环在岩石圈、水圈、生物圈和大气圈之间转运碳。各储库以拍克碳计量；地质储库（沉积岩、化石燃料）的储量远超土壤圈和大气圈。

Photosynthesis captures CO₂:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

Respiration, combustion and decomposition return CO₂ to the atmosphere. Fossil fuel burning has increased atmospheric CO₂ to over 420 ppm, enhancing the greenhouse effect.

光合作用固定二氧化碳。呼吸作用、燃烧与分解释放CO₂回到大气。化石燃料燃烧使大气CO₂浓度超过420 ppm，加剧了温室效应。

Energy insecurity reflects the mismatch between consumption and supply of oil, gas and coal. Energy pathways (pipelines, shipping) can be disrupted. Renewable alternatives and carbon capture and storage (CCS) aim to decarbonise economies.

能源不安全反映了石油、天然气和煤炭消费与供给的错配。能源通道（管道、航运）可能中断。可再生能源与碳捕集封存技术致力于经济去碳化。

5. Globalisation | 全球化

Globalisation is the increasing interconnectedness of the world through flows of capital, goods, information, people and services. The KOF Index measures economic, social and political globalisation.

全球化是世界通过资本、商品、信息、人员与服务的流动而日益互联的过程。KOF指数衡量经济、社会与政治全球化程度。

Key drivers are developments in transport (containerisation, air freight), ICT (fibre optics, satellites) and trade liberalisation (WTO, free-trade agreements). Transnational corporations (TNCs) organise global production networks, often locating headquarters in developed countries and manufacturing in emerging economies.

关键驱动力包括交通发展（集装箱化、航空货运）、信息通信技术（光纤、卫星）以及贸易自由化（世贸组织、自贸协定）。跨国公司组织全球生产网络，总部常在发达国家，制造环节设在新兴经济体。

Globalisation creates winners (emerging economies, skilled workers) and losers (unskilled workers in HICs, traditional cultures). The anti-globalisation movement highlights environmental costs, sweatshops and cultural homogenisation.

全球化既造就赢家（新兴经济体、技能工人），也产生输家（高收入国家的非熟练工人、传统文化）。反全球化运动强调环境代价、血汗工厂和文化同质化问题。

6. Regenerating Places | 区域再生

Place regeneration addresses the decline of former industrial and coastal areas. Deindustrialisation, out-migration and dereliction reduce the economic and social fabric, measured by indices such as the Index of Multiple Deprivation (IMD).

区域再生应对老工业区和沿海地区的衰退。去工业化、人口外迁和废弃化侵蚀了经济与社会肌理，多重剥夺指数等可以衡量衰退程度。

Strategies range from neoliberal approaches (enterprise zones, deregulation) to community-led regeneration (cooperatives, participatory budgeting). Gentrification can revitalise housing but may displace existing communities.

再生策略从新自由主义路径（企业区、放松管制）到社区主导的再生（合作社、参与式预算）不一而足。绅士化能振兴住房，却可能迫使原社区迁离。

Case studies such as the London Docklands and the Eden Project in Cornwall show contrasting regeneration mechanisms: property-led development versus tourism and environmental branding.

伦敦码头区和康沃尔郡伊甸园项目等案例展示了截然不同的再生机制：房产导向的开发与旅游业和环境品牌塑造。

Evaluating success requires assessment of economic, social and environmental outcomes. Sustainable regeneration involves affordable housing, job creation and green infrastructure.

评价成功与否需考察经济、社会与环境成效。可持续再生包含可负担住房、就业创造和绿色基础设施。

7. Superpowers | 超级大国

A superpower exerts influence globally through a combination of economic strength, military capacity, cultural dominance and geopolitical reach. Hard power uses military and economic coercion; soft power relies on diplomacy, aid and cultural attraction.

超级大国通过经济实力、军事能力、文化主导和地缘政治影响力在全球施加影响。硬实力运用军事与经济强制；软实力依赖外交、援助与文化吸引力。

The USA has been the dominant superpower since 1990, but China is emerging through economic growth (Belt and Road Initiative) and technological influence. Russia uses energy resources as a geopolitical lever.

自1990年以来美国一直是主导超级大国，但中国正通过经济增长（一带一路倡议）和技术影响力崛起。俄罗斯将能源资源作为地缘政治杠杆。

Theories of imperial decline and Mearsheimer’s offensive realism explain changing power distributions. Resource demand for rare earths, water and fossil fuels fuels competition in strategic regions such as the South China Sea and the Arctic.

帝国衰亡理论和米尔斯海默的进攻性现实主义解释了权力格局变化。对稀土、水与化石燃料的资源需求加剧了南海和北极等战略区域的竞争。

International institutions (UN, G20, BRICS) and alliances (NATO) both constrain and enable superpowers, structuring global governance and conflict resolution.

国际机构（联合国、二十国集团、金砖国家）与联盟（北约）既约束又助力超级大国，塑造了全球治理和冲突解决机制。

8. Health, Human Rights and Intervention | 健康、人权与干预

Health and development are closely linked; the epidemiological transition describes changes from infectious to non-communicable diseases as countries develop. Indicators include life expectancy, infant mortality and DALYs.

健康与发展密切相关；流行病学转型描述随着国家发展，疾病从传染病转向非传染性疾病的趋势。指标包括预期寿命、婴儿死亡率和伤残调整寿命年。

Human rights are universal but are violated in contexts of conflict, dictatorship and poverty. Genocide, ethnic cleansing and gender discrimination remain global concerns monitored by the UN and NGOs.

人权具有普遍性，但在冲突、独裁和贫困背景下常遭侵犯。种族灭绝、族裔清洗和性别歧视仍然是联合国与非政府组织关注的重点。

Military intervention (responsibility to protect, R2P) and humanitarian intervention are contentious, raising sovereignty and neocolonialism debates. Development aid (bilateral, multilateral, tied aid, NGOs) aims to reduce poverty but can foster dependency.

军事干预（保护责任）和人道主义干预充满争议，引发了主权与新殖民主义的辩论。发展援助（双边、多边、附带条件的援助、非政府组织）旨在减贫，却可能造成依赖。

Successful intervention requires local empowerment, good governance and a long-term approach that aligns top-down and bottom-up strategies, as seen in contrasting case studies such as Rwanda and Afghanistan.

成功干预需要地方赋权、良好治理以及顶层设计与基层策略相协调的长期路径，卢旺达与阿富汗等对比案例就体现了这一点。

---

9. Migration and Identity | 迁移与身份认同

Migration is driven by push factors (unemployment, persecution, conflict) and pull factors (job opportunities, safety, education). Lee’s model and Ravenstein’s laws provide theoretical frameworks.

迁移由推力因素（失业、迫害、冲突）和拉力因素（就业机会、安全、教育）驱动。李的模型和拉文斯坦规则提供了理论框架。

International migration creates diaspora communities and transnational identities. Remittances reaching over US$700 billion annually support source economies but can cause brain drain.

国际迁移生成离散族群和跨国身份认同。每年超7000亿美元的汇款支撑着来源国经济，但也可能造成人才流失。

Host countries experience multiculturalism, which enriches societies yet poses challenges for social cohesion and service provision. Migration policies range from open borders to strict quotas and points-based systems.

接收国经历多元文化主义，丰富了社会但给社会凝聚力和公共服务带来挑战。移民政策从开放边界到严格的配额制和积分制不一而足。

Sovereignty and identity are renegotiated as states balance economic needs with public concerns over cultural change and security, visible in the Brexit debate and EU freedom of movement.

当国家在经济需求与公众对文化变迁和安全问题的担忧之间权衡时，主权与身份被重新协商，这体现在英国脱欧辩论和欧盟人员自由流动中。

---

10. Synoptic Links and Geographical Skills | 综合联系与地理技能

Synoptic questions require you to connect topics, such as how globalisation impacts carbon emissions or how tectonic hazards affect regeneration. Use a systems approach to trace cause-effect chains across themes.

综合性问题要求你联系不同主题，例如全球化如何影响碳排放，或板块灾害如何影响区域再生。运用系统思维追溯跨主题的因果链。

Essential quantitative skills include Spearman’s rank correlation, chi-squared test, measures of central tendency and dispersion, and percentage change. Statistical significance must be interpreted carefully.

核心定量技能包括斯皮尔曼等级相关、卡方检验、集中趋势和离散度测量以及百分比变化。需谨慎解读统计显著性。

Qualitative skills involve coding interviews, mapping emotions or use of place-check frameworks. GIS skills (layered maps, spatial analysis) are needed to analyse patterns and present fieldwork data.

定性技能涉及访谈编码、情绪地图或场所检查框架的使用。需要GIS技能（分层地图、空间分析）来分析格局并展示实地调查数据。

Fieldwork design must address statement, justification, risk assessment and ethical considerations. Your independent investigation (NEA) must refer back to geographical theory and specification links.

田野调查设计须包含陈述说明、理由、风险评估与伦理考量。独立研究（NEA）必须回扣地理学理论与大纲联系。
