The Influence Of Phosphorus In The Rock On Eutrophication In Chaohu Lake In The Phoenix Area

Eutrophication is one of the most serious water quality problems in the world, with increasing human development and utilization of environmental resources, agricultural and industrial production of rapid development, and a large number of nitrogen, phosphorus and nutrients into the lake, the growing phenomenon of water eutrophication. The causes of eutrophication are complex, in accordance with the way of nutrients into the lakes, will result in the pollution of pollution sources are divided into exogenous and endogenous contamination of lake Eutrophication. Phosphorus in the rock is an important representative of the foreign source pollutants.Chaohu Lake in northern Phoenix mountain is widely distributed phosphorus strata. In a special geological structure parts these stratigraphic occurrence of folds and faults cutting broken, coupled with the large-scale exploitation of the human phosphate and its roof and floor of limestone, resulting in a phosphorus layer severe weathering, erosion and leaching, eventually leading to phosphorus nutrients to enter the Chaohu. Chaohu Lake eutrophication problems have become increasingly prominent, serious damage to the water balance of the ecosystem, which restricts the utilization of lake resources to carry out control and governance of the lake eutrophication has become the most urgent issue, in order to safeguard the people’s lives and health economic, social and environmental sustainability and the Chaohu Lake basin, this paper is of great significance.This paper selects Fenghuang Mountain as the researched area, Fenghuang Mountain is located in the special geological structure background. In the research field, we determine the sampling points, using the field generally to find the phosphate point phosphorus experiment found that phosphorus determination of the phosphorus-containing strata and laboratory experimental method for quantitative analysis of the phosphorus content of phosphorus formation in order to determine the distribution of phosphorus stratigraphic range and phosphorusthe level of the amount of phosphorus strata of the study area is divided into low-risk areas,medium risk areas and high risk areas, combined with the northern mountainous area of the mine exploitation status, geological tectonics, weathering and erosion, leaching, delivery of surface water and groundwater, We analyzed the rock phosphorus eutrophication in Chaohu and its prevention recommendations. Through this study, we identified the study area, geological conditions and the distribution of phosphorus-rich layer, to ascertain the phosphorus content of the phosphorus-rich layer and a division of phosphorus pollution risk areas are better able to guide human mining activities, more good protection in Chaohu. Study of eutrophication from the rock source of phosphorus, this paper will open up in the direction of a study of exogenous phosphorus on eutrophication of water bodies, has an important role in guiding the rational development and protection of the Chaohu Lake basin ecosystem.
