Abstract: To quantitatively evaluate dynamic variation of the sustainable development degree of Jilin Province and its affecting factors,time sequence of ecological footprint（EF） of the province from 1994 to 2003 was calculated with focus on analyzing dynamic variations of the EF,ecological budget and EF intensity of the province and their driving mechanisms.Results show that from 1994 to 2003,the EF（percapita） increased from 1.594 to 2.231 hm²,and biocapacity（percapita） from 1.274 to 1.308 hm²,showing that the former rises faster than the latter.As a result,ecological deficit appeared and continued growing.The existence of ecological deficit reflects unsustainability of the development model of Jilin Province.Based on analysis of the causes of the ecological deficit,measures are advanced to reduce and eliminate the ecological deficit in Jilin Province.
