📚 Year 10 Eduqas Geography: Core Knowledge Review | Year 10 Eduqas 地理：核心知识点梳理

Year 10 is a critical year for building a solid foundation in GCSE Geography under the Eduqas specification. This article distils the essential knowledge you will encounter across physical and human geography themes, from river processes to urban change, weather hazards to resource management. Use this as a revision checklist and a quick-reference guide to ensure you understand the key concepts, terminology and case study connections required by your exam board.

Year 10 是为 Eduqas GCSE 地理打下坚实基础的关键一年。本文提炼了你在自然地理和人文地理主题中将会学到的核心知识，从河流过程到城市变迁，从天气灾害到资源管理。将本文作为复习清单和快速参考指南，确保你掌握考试局要求的关键概念、术语和案例联系。

1. River Landscapes and Processes | 河流地貌与过程

Rivers shape the landscape through erosion, transport and deposition. The long profile of a river changes from source to mouth, with upper-course features such as V-shaped valleys, interlocking spurs, waterfalls and gorges. The middle course sees meanders and a wider floodplain, while the lower course develops levees, oxbow lakes and deltas.

河流通过侵蚀、搬运和沉积作用塑造地貌。河流的纵剖面从源头到河口不断变化，上游具有V形谷、交错山嘴、瀑布和峡谷等地貌。中游出现曲流和更宽阔的泛滥平原，下游则形成天然堤、牛轭湖和三角洲。

Key fluvial processes include hydraulic action, abrasion (corrasion), attrition and solution for erosion; and traction, saltation, suspension and solution for transport. The Hjulström curve explains the relationship between particle size and the velocity needed for erosion, transport and deposition.

关键的河流作用包括水力作用、磨蚀（磨蚀）、磨耗和溶蚀作为侵蚀方式；以及推移、跃移、悬移和溶移作为搬运方式。Hjulström 曲线解释了颗粒大小与发生侵蚀、搬运和沉积所需流速之间的关系。

When rivers flood, they deposit fertile alluvium, but flooding becomes a hazard when it affects settlements. Both hard-engineering strategies (dams, levees, channelisation) and soft-engineering approaches (floodplain zoning, wetland restoration) can manage flood risk.

河流洪水会沉积肥沃的冲积物，但当洪水影响居住地时便成为灾害。硬工程策略（水坝、防洪堤、河道渠化）和软工程方法（洪泛平原分区、湿地恢复）都可以管理洪水风险。

2. Coastal Landscapes and Management | 海岸地貌与管理

Coasts are shaped by marine and sub-aerial processes. Key erosional processes include hydraulic action, abrasion, attrition and solution, similar to rivers, but wave type (constructive vs destructive) and fetch determine energy levels. Headlands and bays, wave-cut platforms, caves, arches, stacks and stumps are classic erosional landforms.

海岸由海洋和陆上作用塑造。主要的侵蚀过程包括水力作用、磨蚀、磨耗和溶蚀，与河流类似，但波浪类型（建设波和破坏波）与吹程决定了能量水平。岬角与海湾、波切平台、海蚀洞、海蚀拱、海蚀柱和海蚀残丘是典型的侵蚀地貌。

Longshore drift transports sediment along the beach, leading to depositional features such as spits, bars, tombolos and beaches. Salt marshes and dune systems are important dynamic environments that provide natural flood defence and biodiversity.

沿岸漂移将沉积物沿海滩搬运，形成沙嘴、沙坝、连岛沙洲和海滩等沉积地貌。盐沼和沙丘系统是重要的动态环境，提供自然的防洪保护和生物多样性。

Coastal management strategies must balance hard engineering (groyne, sea wall, rock armour) with soft engineering (beach nourishment, managed retreat, dune regeneration). A cost-benefit analysis is essential to decide the most sustainable approach.

海岸管理策略必须在硬工程（丁坝、海堤、石笼）
