Abstract


Coal mining subsidence pool construction is a product of coal production , coal mining is a major cause geological disasters. In recent years, along with efforts to increase coal mining , coal mining subsidence area continues to expand, resulting in deteriorating ecological environment in mining areas , thus forming a large number of coal mining subsidence pond , has become Huainan City of surface water bodies - kind of special part . Therefore, the study of coal mining subsidence pond water ecological environment , to understand collapse pond phytoplankton species composition and the response of the mine environment , seeking pond phytoplankton succession the main driving factors and nutritional status indicated by the waters to determine the water body pollution levels , types and development trend is very necessary. In this study, in March 2004 - February 2005 on the formation of relatively stable Xie two mine subsidence pool nutrient content and related indicators of water chemistry and chlorophyll a detailed annual survey carried out , while in April 2004 ~ December phytoplankton conducted qualitative and quantitative identification. Thank two mines in mining subsidence on the ecological environment monitoring ponds basis , the focus of pond water body 's nutritional status and the main limiting factors, and habitat characteristics of phytoplankton and its succession law , while the pond fishery resources the situation is also carried out using a simple analysis . All of which collapse pond this - special rational development , utilization and control are of great significance.
