An Analysis of County's Sustainable Development Situation Based on Ecological Footprint Model —take Duan county as an example

Ecological footprint is a new means for the quantitative research of sustainable development. The way can quantitatively measure the influence of human beings on nature. This article calculated and analysed Duan county's ecological footprint、ecological capacity、ecological footprint diversity、development capability and ecological footprint of one million GDP between 1997—2002 by the application of ecological footprint model, the result showed that Duan county's ecological footprint is far higher than its ecological capacity,thus ecological deficit appeared. Index of ecological footprint diversity is low,the development capability of ecological economy system is not strong, but index of ecological footprint of one million GDP is too high,which indicates that the development situation of Duan county is not sustainable currently. Finally,some countermeasure has been put forth for the decrease of ecological deficit and sustainable development in Duan county.
