韩江流域内典型水源保护区的生物多样性分析研究

Biodiversity analysis of typical source water protection areas in Hanjiang river basin

为了消减三江水系连通后续优化工程建设对施工区生态环境造成的不利影响,文章以施工区的水生态监测数据为研究对象,通过在韩江干流区和交接水库区等5个断面各设置了1个监测点,对区域内的浮游植物、浮游动物和底栖生物等优势种和生物多样性进行分析研究,得出了优势种及多样性指数在不同区域内的分布情况,并针对监测的技术数据进行质量控制,旨为更好地保护区域内的生态水环境。

In order to reduce the adverse impact on the ecological environment of the construction area caused by the construction of the follow-up optimization project of the connection of the three river systems,this paper takes the water ecological monitoring of the construction area as the research object,and analyzes and studies the dominant species and biodiversity in the area,such as Phytoplankton,Zooplankton and Benthos,by setting one monitoring point in each of the five sections,such as the main stream area of the Hanjiang River and the junction reservoir area,the distribution of dominant species and Diversity index in different regions is obtained,and quality control is carried out for the monitored technical data,hoping to better protect the ecological water environment intheregion.
