西北黄土高原区生态环境可持续发展的生态足迹动态分析—以宁夏为例

Based on the overview of the background and recent research advances of ecological footprint(EF), the definition and computation method of the EF model are clarified. Then, take Ningxia for example , the thesis calculated and analysed the EF from 2003 to 2007,and made the comparation with the West ,China and the world. Results indicate that the EF of Ningxia has exceeded its eco-capacity, the present developing model is not sustainable,and the absolute value of the ecological deficit is improving year by year. Based on the anlysis, some ideas are given to solve this problem.
