Analysis of Water Resource Carrying Capacity in the Ecological Economic Zone of Dongting Lake

Abstract

In this study, the supportable maximum GDP/ population and the water poverty status were analyzed using the dual indices calculation model and the water poverty index in the Ecological Economic Zone of Dongting Lake in the different planning level years. The results showed that the supportable maximum GDP and population keep on increasing in the Ecological Economic Zone of Dongting Lake in the planning level years, and that in the Yueyang, Changde and Yiyang was the three maximum. On the other hands, the water poverty status in the Ecological Economic Zone of Dongting Lake was improved in the planning level years since the water conservancy project construction, the incremental water supply and the pollutants abatement. Key words: Water Resource Carrying Capacity; Dual Indices Calculation Model; Water Poverty Index; Ecological Economic Zone of Dongting Lake
