河流样式框架：基于水文地貌评估支撑河流景观的可持续修复与管理

河流景观是人类需求与自然基底相互作用形成的复杂、多尺度嵌套的社会生态和水文地貌系统。基于水文地貌学原理的“河流样式框架”为理解河流“形式与过程”之间的关系提供了一个成熟的分析工具。系统梳理河流样式框架的基本原则、具体步骤与核心内容,提出多尺度的空间层级划分、河流样式与地貌单元的分类体系是该框架解释河流特征与河流行为的核心方法。进而在流域尺度依据地貌状况与修复潜力评估结果确定各个河段修复管理的优先次序,在河段尺度通过河流演变轨迹分析预测河流的变化趋势。以期为“基于过程”的河流景观修复设计与行动计划提供理论支持。

River Style Framework: A Hydro-morphologyAssessment Framework for Sustainable RiverscapeRestoration and Management

Riverscape is a complex and multi-scale socioecologicaland hydrogeomorphic system, which is the resultfrom the interaction between human and nature. The "River StyleFramework", based on the principles of hydrogeomorphology,provides a mature learning tool to understand the "form andprocess". The paper made a systematic review of the mainprinciples, procedures and contents of river style framework.The multi-scale spatial framework, the classification system ofriver style and geomorphic units provide the basic approach fordescribing and interpreting river character and behavior. At thewatershed scale, the priority of restoration strategy of each reachcan be identified after the geomorphological condition assessmentand the restoration potential assessment; at the reach scale, with theevolution trajectory analysis of the specific reach, the change trendcan be predicted, and providing knowledge evidence for "processbased"riverscape restoration design and actions.
