摘要
以云南大理市洱海及其流域为例,通过建立湖泊水质指标演变与流域人均GDP增长的计量模型,对环境库兹涅茨曲线(EKC)进行新的检验发现:基于时间序列数据的洱海水质指标与流域人均GDP的拟合曲线,与环境库兹涅茨曲线相比较呈现了不同特征和形状:既有经典的倒U型的曲线,也有U型、N型和同步型的曲线。倒U型的曲线表明洱海治理措施的有效性;U型、N型和同步型的曲线表明湖泊面源污染和富营养化控制的复杂性,湖泊面源污染和富营养化控制需要寻求的新解决思路和多种措施的配合。在借鉴国外经验和国内有价值的研究成果的基础上,本研究将有利于通过结构调整对面源污染从源头实施总量控制,推进"工程治污"与"结构控源"措施的优化与配合,辅助湖泊水环境的规划与管理及决策。
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.
