三峡大学文思湖生态需水量估算

Study on Ecological Water Demand of Wensi Lake in China Three Gorges University

河流系统的生态需水量是指维持河流正常的生态结构和功能所需要的一定水质量最小水量,具有明显的时空变化特征。文思湖属于学校景观河道,目前河流主要水源为校园生活污水,河道内杂草丛生,富营养化严重。针对文思湖生态需水量作出初步估算,为控制水污染、改善水质提供合理的方案,以构建和保持健康和谐的水体环境。

The ecological water demand by the river system is the least amount of water needed to maintain the natural ecological structure and the function of the river,having the obvious characteristics of spatial and the time evolution.Wensi Lake is the view river of the school,the river main source of water is the sanitary sewage in the campus at present,weedy in the river,eutrophication is serious.The ecological water demand of Wensi Lake was preliminarily estimated,so as to offer the rational scheme for controlling the water pollution and improving water quality,and construct and maintain the health and harmonious water body environment.
