摘要
江苏省境内的白马湖作为区域性洪涝调蓄水库,不仅承担防洪治涝作用,还具有生态修复与改善的功能。针对白马湖近年出现的高锰酸盐指数偏高问题,结合往年资料、水质检测结果和现场调研情况,从内外源污染、季节影响、藻类、生态系统退化(沉水植被减少)等方面分析了白马湖高锰酸盐指数超标的成因,并提出了构建滨河湿地、入湖河流水生态环境保护与修复策略,为提升该区域生态服务功能提供技术保障。
Baima Lake serves as a regional flood control reservoir in Jiangsu Province,which not only bears the role of flood control,but also acts as an ecological system to improve and restore the ecological environment.In view of the problems of high values of permanganate index in Baima Lake recent years,the data of previous years combining the field study are investigated.The reasons resulted in the excessive permanganate index are analyzed from the perspectives of exogenous pollution,endogenous pollution,seasonal influence,microalgae growth,ecosystem degradation(reduced submerged vegetation)and other factors.Meanwhile,restoration strategies for riverfront wetland construction,water environment protection and ecology restoration are proposed to provide technical support for enhancing the ecological serves.
