Investigation,evaluation and analysis of sediment in Dawangtan Reservoir
In order to solve the sediment problem of Dawangtan Reservoir,it is necessary to investigate the sediment situation of various reservoir zones including the sediment depth,quantity,extent of pollution and range of distribu-tion.Through the analysis of heavy metal elements and nutrient salt,water eutrophication,aquatic organisms in the sediment of Dawangtan Reservoir,the spatial distribution characteristics were revealed;the pollution extent and dis-tribution of sediment in the reservoir were evaluated by analysis of potential ecological risk index,hydrobios rich-ness index and all water quality indicators.
