Study on the Urbanization Process of Kunming City and Its Impacts on the Water Environment of Dianchi Lake
摘要
Abstract
[ Objective ] We aimed to analyze the urbanization process of Kunming City and its impacts on the water environment of Dianchi Lake. [Method] Using the Analytic Hierarchy Process (AHP) ,we assessed the urbanization leve of Kunming in 1998 -2008 based on composite indicator evaluation system. Afterwards, we calculated water pollution composite index of Dianchi Lake and introduced the EKC to set up a coupling relationship model between the urbanization level and water environment quality. [Result] During 1998 -2008,the urbanization level of Kunming increased gradually,that is,it was lower than 0. 30 before 2002,with slow growth; at the later stage,it grew fast,and reached 0.75 in 2008. Water pollution composite index of Dianchi Lake showed that Dianchi Lake was polluted seriously,especially Caohai. From the EKC,we can see that the relationship curves between the urbanization level of Kunming and water pollution composite index of Dianchi Lake were akin to inversed U shapes, and still at an antagonistic stage at present. [ Conclusion ] The research could provide scientific references for discussing the relationship between urbanization process and water environment.关键词
