[Ecological footprint and available ecological capacity in Chongqing region].

Based on the statistical data of Chongqing, the ecological footprint of Chongqing was calculated in this paper. The results showed that the per capita ecological footprint was 1.653566 hm2, per capita ecological capacity was 0.280393 hm2, and ecological surplus of deficit was 1.373173 hm2. The per capita ecological footprint was 0.5335 hm2 (47.64%) higher but the per capita ecological capacity was 0.5196 hm2 (64.95%) lower, and the ecological surplus of deficit was about 3.43 times of the average national level. These results showed that the ecological footprint of Chongqing was beyond the available ecological capacity, and its social and economic development was not sustainable. The strategies on reducing ecological deficit in this region, such as reducing ecosystem population, increasing public finance income, and controlling environmental pollution, were also put forward.
