Abstract: Characteristics of the ecological footprint and ecological sustainable development in Wencheng from 2000 to 2009 was analyzed and evaluated using ecological footprint model and data aggregation and other analytical methods. The results showed that: the ecological footprint per capita of Wencheng increased from 0.5918 hm2 per person in 2000 to 0.6352 hm2 per person in 2009. Additionally, the ecological capacity per capita of Wencheng reduced from 0.6189 hm2 per person in 2000 to 0.5281 hm2 per person in 2009. The ecological deficit per capita showed a gradually increasing trend in Wencheng in recent 10 years. From 2000 to 2009, the sustainable development index of arable land resources per capita decreased from 0.5112 to 0.4540 and showed a state from lowly sustainable to lowly unsustainable. The model predicts that ecological footprint per capita of Wencheng will reach 0.6519 hm2 per person, while the ecological capacity of arable land per capit. will drop to 0.4917 hm2 per person by 2019. Then ecological deficit will increase to 0.1602 hm2 per person and sustainable development index will decrease to 0.4300. The ecological stress of Wencheng will more and more serious. To inhibit the upward trend of ecological footprint, increase the ecological capacity and then maintain the ecologically sustainable development of Wencheng, we should control population, change the traditional concept of consumption, curb the ecological environment, improve the utilization rate per unit land and take other measures etc.

Key words: ecological footprint, ecological capacity, sustainable development, Wencheng
