基于洪水资源化利用的温带季风气候区河流生态修复模式研究OA

Rivers in temperate monsoon climate zones in China face a spatiotemporal mismatch between concentrated flood discharges during the flood season and severe ecological baseflow deficiencies during the non-flood season.While traditional flood control projects ensure water security,they concurrently exacerbate river habitat fragmentation.Therefore,developing a systematic governance model that integrates flood resource utilization with ecological restoration has become a key pathway for addressing bottlenecks in regional high-quality development.Based on literature review,theoretical and problem analysis,and case studies,this paper systematically examined the theoretical and practical dimensions of flood resources,including their resource-oriented nature,functional attributes,and utilization feasibility.Taking the Yihe River as a typical case,it provided an in-depth analysis of governance measures such as cascade storage,inter-basin water transfer,and ecological flow regulation.A river ecological restoration model for temperate monsoon climate zones was proposed,grounded in flood pulse and fundamental ecological theories,implemented through cascade storage and connectivity regulation,driven by hydrological and ecological process coupling,and constrained by threshold control.This model aims to achieve multi-objective synergy between flood resource utilization and regional high-quality development,offering a reference for transitioning rivers in temperate monsoon zones from engineering-based flood control to collaborative ecological governance.
