Fine flushing and rough supplementing type riverbed substrate habitat restoration method and system for small hydropower station exiting river reach
The invention discloses a'fine flushing and coarse supplementing 'type riverbed substrate habitat restoration method and system for a small hydropower station quit river reach, and relates to the field of ecological restoration, and the method comprises the steps: obtaining the hydrologic and geomorphic information of the implemented small hydropower station quit river; key habitat area distribution in the river reach influenced by small hydropower station quitting is determined according to hydrological and landform information, and the matrix particle size condition of the key habitat area and the part and thickness of water flow scouring and silting are determined; determining a riverbed substrate habitat restoration scheme (including pebble supplement, boulder group arrangement, ecological spur dike arrangement and ecological water guide barrage arrangement) by combining the key habitat restoration layout map; simulating the restoration effect based on the riverbed substrate habitat restoration scheme and the hydrodynamic sediment transport model, and adjusting the riverbed substrate habitat restoration scheme according to the simulation result to obtain the optimal riverbed substrate habitat restoration scheme. According to the method, the damaged river reach of river degradation caused by small hydropower station quitting can be recovered, and the natural landform state of the river is recovered.
本申请公开了一种小水电退出河段“冲细补粗”式河床底质生境修复方法及系统，涉及生态修复领域，该方法包括：获取已实施小水电退出河道的水文地貌信息；根据水文地貌信息确定小水电退出影响河段内的关键生境区域分布，并确定关键生境区域的基质粒径情况以及利用水流冲淤的部位和厚度，结合关键生境恢复布局图确定河床底质生境修复方案(包括卵石补充、漂石群布设、生态丁坝设置及生态导水堰坝设置)；基于河床底质生境修复方案及水动力泥沙输移模型对修复效果进行模拟，并根据模拟结果调整河床底质生境修复方案，以得到最优的河床底质生境修复方案。本申请能够恢复由于小水电退出导致河流退化的受损河段，恢复河流自然地貌状态。
