Abstract
According to the basic principle and the calculation model of ecological footprint, the spatial patterns and dynamic laws of resources in Chongqing 2000 - 2009 were analyzed. The result showed that water resources per capita ecological footprint and per capita water resources capacity of Chongqing fluctuated in a downward trend. The ecological footprint of water resources fell from 3. 50 hm /person in 2000 to 2. 64 hm /person in 2009. Water resources carrying capacity fell from 6. 05 hm /person in 2000 to 3. 48 hm /person in 2009, and reached the trough period in 2001 and 2006. In the space, the ecological footprint of Chongqing waters resources and water resources carrying capacity showed obviously different spatial distribution. The water resources carrying capacity and ecological footprint of the developed metropolis and the west Chongqing were low. One of the most outstanding was the Yuzhong district. The water ecological footprint and water resources carrying capacity of Three Gorges reservoir and the southeast ecological was relatively high, especially in Chengkou County and Wuxi County. In addition , the 40 districts and counties of Chongqing general water resources ecological footprint was substantially below the carrying capacity of water resources. There were ecological surplus. But some of the districts of water resources ecological deficit were still serious.关键词
