Based on statistical data for Chongqing Municipality,P.R.China,and using ecological footprint theory,a dynamic calculation was carried out to determine the ecological footprint of Chongqing during the initial ten years that the area was under direct central government administration.The result indicates the following: the per capita ecological footprint in Chongqing increased gradually from 1.3767 49 hm2 in 1997 to 2.113 609 hm2 in 2006;the ecological capacity per capita decreased from 0.438 07 hm2 to 0.406 153 hm2;and the ecological deficit increased from 0.938 671 hm2 to 1.707 456 hm2.By 2010,it is forecasted that: the ecological footprint per capita will be 2.956 hm2;the ecological capacity per capita will be 0.385 1 hm2;and the ecological deficit will be 2.570 9 hm2.All these indicate that Chongqing is entirely in an ecological deficit state with the deficit increasing annually.The development mode of the city is an unsustainable one.In this paper,we summarize the calculated result,point out the reasons for ecological deficits in Chongqing,and conclude with some instructive advice for referral to the Chongqing government.
