Spatio-temporal Characteristics of Sustainable Development in Xinjiang Based on Improved Relative Carrying Capacity of Resources

Endowment of natural resources and economic resources is not only important guarantee of regional population development,but also basis of sustainable development.Based on the improved model of relative carrying capacity of resources,we calculate the relative population carrying capacity of resources as well as relative economics carrying capacity of resources in Xinjiang from2000to 2010.We also discuss the temporal evolution and differences characteristics of 15 prefectures and cities in Xinjiang.The implications from the study are as follows:(1)Western China regions as the reference areas,Xinjiang was in surplus population and economy overload stage between 2000 and 2005;from 2006 to 2010 in double surplus stage.(2)Compared with twelve western provinces,energy resources were advantageous to sustainable development of Xinjiang,while water resources were restricting the population and economic development.(3)Setting Xinjiang as the reference zone,Karamay City and Kizilsu Kirgiz Autonomous Prefecture had the largest surplus degree of relative population and economic carrying capacity of resources,and the most overload areas were Kashgar and Turpan.(4)According to the bearing state of relative population and economic carrying capacity of resources,we classified 15 prefectures and cities in Xinjiang into four matching models.
