摘要
随着水环境质量的持续改善,我国河流水生态、水健康问题逐渐得到重视,为掌握上海中心城区河流水生态状况及变化趋势,诊断河流健康和识别主要问题,以上海市典型中心城区徐汇区为例,筛选8条典型河流,分季度开展河流水生态环境质量持续跟踪监测与河流健康评价。结果表明:徐汇区典型河流存在水体富营养化、生物多样性低及外来入侵物种福寿螺扩散等问题;河流总体处于亚健康至健康状态,37.5%为健康状态,62.5%的河流处于亚健康状态,处于亚健康状态多为河流规模相对较大的河流,小型河流多为健康状态。因此,中大型河流健康度的提升是后续重点关注方向。
China′s river aquatic ecology and health issues are gradually gaining attention with the continuous improvement of water environment quality.In order to grasp the water ecological status and changing trends of rivers in Shanghai central urban area,diagnose river health and identify major problems,eight typical rivers of Xuhui District were selected and the continuous tracking monitoring of river water ecological environment quality and river health assessment were carried out in different quarters.The results showed that the river had the problems of eutrophication of water bodies,low biodiversity and the proliferation of invasive alien species of Fucus snails in Xuhui District.River health status was between sub-healthy to healthy,37.5%of the rivers were healthy and 62.5%the rivers were sub-healthy.In the sub-healthy status mainly for the relatively large river scale,small rivers were mainly healthy.Therefore,medium and large river health enhancement were the focus of future attention.
