巢湖富营养化的历程、空间分布与治理策略（19842013年）
The process, spatial and temporal distributions and mitigation strategies of the eutrophi-cation of Lake Chaohu(1984 2013)
摘要
Abstract
In the present study, we analyzed the eutrophication process in Lake Chaohu and its correlation with socioeconomic and population development in Hefei city. We also investigated the spatial and temporal distribution characteristics of total nitrogen, total phosphorus, ammonia nitrogen, permanganate index and cyanobacterial blooms in 2012 and 2013 in Lake Chaohu. The results showed that the water quality of Lake Chaohu started to deteriorate in 1984, and down to the worst in 1994 due to the increasing pollution and lacking of capital investment. During the period of 1995 2007, the water quality was getting better because of the limitation of direct waste water and sewage draining into the lake. After year 2008, the water quality did not show significant improvement and maintained a high level of eutrophication. In terms of spatial distributions, eutrophication in Lake Chaohu presented obviously different patterns: eutrophication level gradually degrades from the west to the east, which attributes to the source of pollution from the primary three rivers(Nanfei River, Shiwuli River and Pai River) in the west. The results from investigation also showed that the pollution from these rivers was less in 2013 than that in 2012, and the reduction in Shiwuli River was more apparent than that in Nanfei River. However, the reduction of pollution in the whole lake was not significant. Our findings suggest that in order to further reduce pollution, it is necessary to change economic development pattern and industrial structures and execute targeted pollution source control.关键词
