基于生态足迹模型的西北干旱绿洲农业区可持续发展评价——以张掖市为例

Study on Sustainable Development of oasis Agriculture Cities in Arid Areas of Northwest China Based on Analyzing Ecological Footprints ——A Case Study in Zhangye City

利用生态足迹和生态承载力的理论和方法,以西北干旱绿洲农业区城市张掖为例,对其可持续发展状况及程度进行了评价和度量。结果表明:张掖市2009年人均生态足迹为3.798hm2,人均承载力为1.453hm2,人均生态赤字为2.345hm2。在此基础上,对张掖市的生态可持续发展进行了评价,并提出解决对策。

Based on the theories and methods of ecological footprint（EF） and ecological carrying capacity（ECC）,a case study on sustainable development in Zhangye City,a city in an arid area of northwest China,is carried out using the EF and ECC models,and the EF and ecological carrying capacity of Zhangye City in 2009 was calculated and analyzed in this paper.The results showed that the ecological footprint demand and the ecological capacity are respectively 3.798hm2 per capita and 1.453hm2 per capita in Zhangye City,and the ecological deficit is 2.345hm2 per capita.Based on that,the sustainable development of Zhangye City was evaluated and relevant measures were proposed.
