CITY ECONOMIC DEVELOPMENT AND EMPIRICAL ANALYSIS OF THE LAKE WATER ENVIRONMENTAL PROTECTION——ERHAILAKE AND ITS WATERSHED AS AN EXAMPLE
以洱海流域为例，通过建立水质目标与人均GDP增长模型，检验环境库兹涅茨曲线，发现曲线形态多样，表明非点源污染和富营养化治理需要新思路和多种措施协调。
Erhai lake,Yunnan Dali and its watershed as an example,through the establishment of lake and river basin water quality objectives for the evolution of GDP per capita growth model,the environmental Kuznets curve(EKC) found a new test:Based on the time-series data water quality objectives for the Lake Erhai basin per capita GDP and the fitting curve,shown with the environmental Kuznets curve and shape of different features,both the classic inverted U-shaped curve,there are U-,N-type and synchronization of the curve type.Inverted U-shaped curve shows that the effectiveness of management measures Erhai;U-type,N-type and synchronization of the curves show that the lake-based non-point source pollution and eutrophication control of the complex nature of non-point source pollution and lake eutrophication control need to seek new ideas and a variety of measures to solve the co-ordination.
