Description :
Firstly, the ecological supply and demand balance was calculated and evaluated, and secondly, the ecological carrying capacity index (ECCI) was derived for each county of China in 2007, and finally this paper systematically evaluated the ecological carrying capacity supply-demand balance of China. The results showed that ecological deficit appeared to be the main characteristic of ecological carrying capacity supply-demand balance in 2007 of China at county scale. The spatial distribution of the ecological carrying capacity demand-supply was unbalanced ranging from significant overloading to affluence from southeastern to northwestern part of China. It appeared to be more dominant in regions located at coastal areas which had a generally higher population density. Along with the rapid development and urbanization trends in China, ecological deficits in these regions will become more severe.
