Causes of Pollution of the DianchiLake and New Control Measures

PENG Yongan,ZHU Tong(Yunnan Institute of Geography,Yunnan University,Kunming 650223)  
The outlet of water body of Dianchi Lake is located in the southern area, but the main pollution load is in the northern area. The flow of Dianchi Lake is always rush from North to South. Because of the slow lake flow, over 90% of the pollutants in the waste water deposit on the bottom of Dianchi Lake.Hence there are mainly two factors causing the pollution in Dianchi Lake. One is the slow lake flow, the other is the intruding of the polluted water. There are two ways to deal with the pollution situation. One is to speed up the lake flow,the other is to stop the polluted water from intruding to the southern lake.In light with the situation that the northern lake polluted the southern lake of the Dianchi,the new solution identified is to change the original outlet of Dianchi Lake by digging up a new canal and putting Dianchi Lake flow backwards to the north. By so doing, the main pollution load can be closed to the new outlet and kept away from the original one, part of the polluted water in Kunming city will not directly discharge into the Dianchi Lake. Even if the polluted water discharged into the Dianchi Lake, it is possible to let it rapidly flow out of the northern Dianchi Lake.In a word, the elevated potential of high water pressure can effectively prevent the southward intrusion of pollution load from northern part, offering a basic solution to the pollution problems of the Dianchi Lake.

5 The relationship between the characteristics of the ecological environment of the region of Dianchi Lake and the urban development of Kunming was analysed in this paper. The restricting factors which affected the regional Dianchi Lake's ecological and economical capacity were emphasized. It was suggested that in order to hamonise the development of the regional environment of Dianchi Lake and the urbanization of Kunmin, the reconstruction of the urban function should be considered on the basis of the present situation of eco-economy in Kunming.;RELATIONSHIP BETWEEN THE CHARACTERISTICS OF ECO-ECONOMICAL CAPACITY FOR THE REGION OF DIANCHI LAKE AND THE URBAN FUNCTIONS IN KUNMINGDuan Changqun Wang Huanxiao ( Depcrtment of Biology, Yunnan University, Kunming )[J];Urban Environment & Urban Ecology;1992-03
