Abstract: |
Abstract: The ecological footprint composition and space difference of eco-efficiency in districts and counties around Nansihu Lake was analyzed with related statistical data of 2007, and then the sustainability was assessed in the method of quadrant analysis by footprint per capita and eco-efficiency. The results show that the total ecological footprint presents a pyramid structure，and the top county is 5.7 times more than the bottom one. In general, the proportion of carbon footprint land is as high as 44.3%, while that of built-up land is only 6.66%. The spatial eco-efficiency distribution assumes a pattern of descending from south to north obviously. Yutai, Liangshan, Jinxiang and Sishui locate in quadrant three, which implicates the best sustainability, while Tengzhou, Xuecheng and Tongshan locate in quadrant one, which means the worst.
