| 中文摘要: |
| 在河流生态系统嵌套层级结构中，地貌单元作为水流和泥沙输移过程的物理表现，是表征河流形态的重要斑块。多样的河流地貌单元特征决定了栖息地的多样性特征，为生态过程提供了物理基础。为更好地理解地貌单元的结构与功能，通过辨析河流地貌单元内涵，对其分类体系与识别方法、地貌单元的生态响应进行了归纳梳理，并总结了河流地貌单元在栖息地调查评估、河流地貌单元制图及河流分类等方面的应用，从而为认识自然河流、修复受损河流提供技术支持。 |
| 英文摘要: |
| In the nested hierarchy of river ecosystems, geomorphological units, as physical manifestations of water and sediment transport processes, are important patches that characterize river morphology. The diversity of river geomorphological units determines the diversity of habitat features and provides the physical basis for ecological processes. In order to better understand the structure and function of geomorphic units, in this paper we defined the typical river geomorphological units, reviewed their classification systems, identification methods and the ecological responses, and summarized the application of river geomorphological units in habitat survey and assessment, river geomorphological unit mapping and river classification. Our study will provide technical support to understand natural rivers and restore damaged rivers. |
