河道生态修复监测指标评价研究

Research on the monitoring index evaluation of river ecological restoration

河流生态修复是维持健康河流的重要举措,而生态修复系统评价是生态修复治理效果的重要考核依据。以北京市沙河水库上游生态流域修复治理工程为例,基于现状生态修复效果评价相关研究,选取多元评价指标,增加工程修复前后指标监测,运用数理统计等方法,对监测数据进行评价分析,综合评估沙河水库上游小流域的生态修复效果,分析结果表明,经生态治理修复后的流域,水质有了明显改善,生境种类增多,入沙河水库生态基流量得到保障。该研究方法可为今后生态修复相关研究工作提供参考。

River ecological restoration is an important measure to maintain healthy rivers, and the evaluation of ecological restoration system is an important basis for the assessment of ecological restoration and governance effect.This study in Shahe Reservoir upstream ecological basin restoration project as an example, based on the relevant research on current ecological restoration effect evaluation, select multiple evaluation indicators, increase the monitoring of indicators before and after the project restoration, using mathematical statistics, the monitoring data, comprehensively evaluate the ecological restoration effect of the upstream small watershed. The results show that in the watershed after the ecological restoration, water quality has significantly improved, habitat species increased, and the ecological base flow into Shahe Reservoir is guaranteed. The research method provides a reference for the future research work related to ecological restoration.This research method can provide a reference for future research on ecological restoration.
