1. Coastal Landscapes and Processes | 海岸景观与过程
Fetch: The uninterrupted distance of open water over which the wind blows without significant change in direction. A longer fetch allows waves to build up more energy, producing higher and more destructive breakers.
吹程 (Fetch): 风在无显著方向变化下吹过开阔水域的连续距离。吹程越长，波浪积聚的能量越多，形成的拍岸浪也越高、破坏力越强。
Swash: The forward movement of a wave up the beach after it breaks, carrying sand and pebbles landwards. Swash velocity and the angle at which it occurs significantly influence beach profile and sediment transport.
冲流 (Swash): 波浪破碎后沿滩面向上方冲刷的水流，将沙粒和卵石向陆地带去。冲流的速度及其前进角度对海滩剖面和沉积物搬运起着关键作用。
Backwash: The return flow of water down the beach, pulling material back towards the sea. Where backwash dominates over swash, beaches tend to be steeper and narrower, often leading to net erosion.
回流 (Backwash): 海水沿滩面向回退的水流，将物质带回海中。当回流作用强于冲流时，海滩往往更陡更窄，并常导致净侵蚀。
Longshore drift: The zigzag movement of sediment along a coastline, driven by angled swash and straight gravity-controlled backwash. It is the main process responsible for building spits, bars and tombolos.
沿岸漂移 (Longshore drift): 沉积物在斜向冲流和受重力控制的垂直回流作用下，沿岸线呈 Z 字形移动的过程。它是形成沙嘴、沙坝和连岛沙洲的主要机制。
Hydraulic action: The physical force of waves compressing air into cracks in coastal cliffs; the sudden pressure release can shatter rock. Combined with abrasion, it drives rapid cliff retreat in high-energy environments.
水力作用 (Hydraulic action): 波浪将空气压入崖壁裂缝的物理力量；压力的骤然释放可致岩石碎裂。与磨蚀共同作用，在高能海岸环境中促使崖壁快速后退。
2. Glacial Systems and Landscapes | 冰川系统与景观
Plucking (quarrying): The process by which meltwater freezes onto bedrock, then as the glacier moves, fragments of rock are torn away and incorporated into the ice. This is most effective where joints or bedding planes are present.
拔蚀 / 掘蚀 (Plucking): 融水在基岩上冻结，冰川移动时将岩石碎块剥离并融入冰体的过程。在节理或层理发育的岩石中，拔蚀尤为有效。
Glacial abrasion: The wearing away of bedrock by rock fragments embedded in the glacier’s base as it slides over the surface, leaving striations and polishing the landscape. It contributes to the deepening of corries and U-shaped valleys.
冰川磨蚀 (Glacial abrasion): 冰川底部夹带的岩屑沿基岩表面滑动时刮磨岩石的过程，留下擦痕并使地貌变得光滑。它是加深冰斗和 U 形谷的重要力量。
Corrie (cirque): An armchair-shaped hollow formed by glacial erosion at the head of a valley, often containing a tarn. Overdeepening occurs as rotational flow of ice concentrates erosion at the base.
冰斗 (Corrie / cirque): 冰川侵蚀在谷地源头塑造的扶手椅状凹地，常包含冰斗湖。冰体回转流动使侵蚀集中于底部，从而形成深度显著增大的洼地。
Arête: A narrow, knife-edged ridge separating two adjacent corries or valleys. It forms when back-to-back corrie walls are eroded backwards until only a sharp crest remains.
刃脊 (Arête): 分隔相邻两个冰斗或谷地的狭窄刀形山脊。背靠背的冰斗壁不断向后退蚀，直至仅剩一道锋利的山脊。
Drumlin: An elongated, streamlined hill of glacial till, with a blunt stoss end facing up-ice and a tapered lee end pointing down-ice. Drumlin swarms indicate the direction of past ice movement.
鼓丘 (Drumlin): 由冰碛物组成的流线型长丘，迎冰面陡钝，背冰面缓尖。鼓丘群标示了远古冰流的方向。
3. Water and Carbon Cycles | 水循环与碳循环
Evapotranspiration: The combined loss of water to the atmosphere through evaporation from surfaces and transpiration from plants. It is a major pathway for returning moisture to the atmosphere, driving precipitation and cloud formation.
蒸散发 (Evapotranspiration): 水分通过地表蒸发与植物蒸腾共同进入大气的过程。它是将水汽送回大气的主要途径，推动降水和云的形成。
Infiltration: The downward movement of water into the soil surface. Infiltration capacity depends on soil texture, structure, antecedent moisture and vegetation cover; reduced infiltration can increase overland flow and flood risk.
入渗 (Infiltration): 水向下进入土壤表层的运动。入渗能力取决于土壤质地、结构、前期含水量和植被覆盖；入渗减弱会增加地表径流与洪水风险。
Carbon sink: Any reservoir that absorbs more carbon dioxide from the atmosphere than it releases, such as mature forests, oceans and peatlands. The oceanic carbon sink absorbs around a quarter of all anthropogenic CO₂ emissions.
碳汇 (Carbon sink): 从大气中吸收的二氧化碳多于其释放量的储存库，如成熟森林、海洋和泥炭地。海洋碳汇吸收了约四分之一的人为排放二氧化碳。
Carbon sequestration: The long-term storage of carbon in solid or dissolved form, whether naturally (e.g. in peat bogs) or artificially (e.g. carbon capture and storage technology). It is a key mitigation strategy for climate change.
碳封存 (Carbon sequestration): 将碳以固态或溶解态长期储存的过程，既包括自然方式（如泥炭沼泽），也包括人工方式（如碳捕集与封存技术）。它是应对气候变化的重要减缓策略。
Percolation: The vertical movement of water deeper through permeable rocks within the groundwater system. Percolation feeds the water table and sustains base flow in rivers during dry periods.
渗透 (Percolation): 水在可透水岩石中向深处垂直移动进入地下水系统的过程。渗透过程补给地下水位，并在旱季维持河流的基流。

地方 (Place): 地球上因独特的人与自然特征及人们赋予其的主观意义和依恋而得以区分的特定地点。与抽象的空间不同，地方充满了身份、情感和记忆。
Placelessness: The loss of distinctive local character in a landscape, often due to globalisation and the spread of homogeneous chain stores and architecture. It is associated with standardised environments that could be anywhere.
无地方性 (Placelessness): 因全球化以及同质化连锁商店、建筑的蔓延，导致景观失去独特地方特色的现象。与之相伴的是千篇一律、毫无地方辨识度的环境。
Endogenous factors: Internal characteristics that shape a place’s identity, such as its relief, geology, drainage, land use patterns, built environment and cultural traditions. These factors provide the roots of local distinctiveness.
内生因素 (Endogenous factors): 塑造地方特征的内部要素，如地形、地质、水系、土地利用方式、建成环境和文化传统。这些因素构成了地方独特性的根源。
Exogenous factors: External influences on a place, including flows of people, capital, ideas and resources. Migration, foreign investment and media representation can rapidly transform a place’s demographic profile and economic function.
外生因素 (Exogenous factors): 影响一个地方的外部力量，包括人流、资金流、观念流和资源流。移民、外商投资和媒体再现能迅速改变一个地方的人口结构与经济功能。
Gentrification: The process whereby wealthier newcomers move into a formerly working-class inner-city area, renovating property and displacing previous residents due to rising rents. While it may boost local services, it often erodes established communities.
绅士化 (Gentrification): 高收入群体迁入曾经的劳工阶层内城区，翻新房产并因租金上涨而取代原有居民的过程。虽然它可能提升本地服务档次，却常常侵蚀原有的社区纽带。
5. Contemporary Urban Environments | 当代城市环境
Urbanisation: The increasing proportion of a country’s population living in urban areas, driven by rural-to-urban migration and natural population growth. Globally, the urban population now exceeds the rural population and is concentrated in megacities.
城市化 (Urbanisation): 一国城市人口比例不断上升的过程，由乡村向城市迁移以及城市自然增长所推动。目前全球城市人口已超过农村人口，并高度集中在超大城市中。
Suburbanisation: The outward expansion of a city into surrounding rural land, often facilitated by improved transport links and rising car ownership. It can lead to urban sprawl and increased commuting distances, as well as the growth of edge cities.
郊区化 (Suburbanisation): 城市向周边乡村土地的外向扩张，常常得益于交通改善和汽车普及。它能引起城市蔓延和通勤距离增加，并催生边缘城市。
Counter-urbanisation: Population movement from urban areas out to smaller settlements and rural fringes, motivated by perceived better quality of life, remote working opportunities and lower house prices. It can reverse inner-city decline but puts pressure on rural housing markets.
逆城市化 (Counter-urbanisation): 人口从城市地区向小型定居点和乡村边缘迁移的现象，其动因包括对更高质量生活的向往、远程工作机会和较低的房价。它可以扭转内城衰退，但也给乡村住房市场带来压力。

韧性 / 复原力 (Resilience): 一个系统、社区或社会及时且有效地抵御、吸收、适应灾害影响并从中恢复的能力。建设韧性涵盖预警系统、抗灾基础设施和社会安全保障。
Subduction zone: A convergent plate boundary where an oceanic plate sinks beneath a continental or another oceanic plate into the mantle. Subduction generates deep ocean trenches, powerful earthquakes and explosive volcanic arcs.
俯冲带 (Subduction zone): 大洋板块向大陆板块或另一大洋板块下方俯冲深入地幔的汇聚型板块边界。俯冲作用造就了深海沟、强震和爆发式火山弧。
Magnitude (Richter scale): A logarithmic measure of the energy released by an earthquake. Each whole-number increase represents a tenfold increase in ground motion and about 31.6 times more energy, though the scale is now largely superseded by moment magnitude (Mw).
震级（里氏震级）(Magnitude): 衡量地震释放能量的对数标度。每增加一整级，地表震动幅度约大十倍，释放能量约增加 31.6 倍，不过目前多已改用矩震级 (Mw)。
9. Development and Inequality | 发展与不平等
