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

Riverscapes are a complex and multi-scale socio-ecological and hydrogeomorphic system, which is the result from the interaction between human and nature. The "River Style Framework", based on the principles of hydrogeomorphology, provides a mature learning tool to understand the "form and process". The paper made a systematic review of the main principles, procedures and contents of river style framework. The multi-scale spatial framework, the classification system of river style and geomorphic units provide the basic approach for describing and interpreting river character and behavior. At the watershed scale, the priority of restoration strategy of each reach can be identified after the geomorphological condition assessment and the restoration potential assessment; at the reach scale, with the evolution trajectory analysis of the specific reach, the change trend can be predicted, and providing knowledge evidence for "process-based" riverscape restoration design and actions.
