环鄱区水污染生态足迹的时空分异、驱动因素及用水匹配研究

Spatio-temporal Differentiation and Driving Factor of Water Pollution Ecological Footprint and Its Water Use Matching in the Poyang Lake Ecological Economic Zone

根据水资源生态足迹的基本原理和计算模型,构建了环鄱区水污染生态足迹模型;利用LMDI模型分析了2010—2013年环鄱区水污染生态足迹分异变化的驱动因素,结合泰尔指数分解方法分析了其区域差异性;基于经济和生态视角构建了环鄱区各城市的用水匹配指数,通过指数矩阵对各城市的水资源消耗公平性进行评价,并从总体上对环鄱区各城市水污染生态足迹情况进行判断。

According to the basic principle and calculation model of water resources ecological footprint in this paper,constructed water pollution ecological footprint model of the Poyang Lake Ecological Economic Zone(PLEEZ)and discussed the law of itsspatio-temporal differentiation.The driving factors of differentiation change for water pollution ecological footprint model in the PLEEZ was analyzed with the LMDI model from 2010 to 2013,and the regional difference was analyzed by combining the Thiel index decomposition method.Finally,the water matching index of each city for PLEEZ was constructed based on the economic and ecological perspective,the fairness of the water resources consumption in each city was evaluated through the index matrix,and judged the water pollution ecological footprint of each city in the PLEEZ in general.
