| Abstract: |
| Ecological footprint is a useful indicator for measuring the pressure on natural capital imposed by human being and assessing sustainable development status.In this paper,we calculate and analyze the ecological footprint of Yulin during the period from 1995 to 2004 by using the model.The results are as follows: the ecological footprint has grown from 0.5274 hm2/capital to 0.8066 hm2/capital with the increase rate of 52.95%,the structure of ecological footprint has changed a lot: the proportion of cropland footprint has decreased largely which is from 71.0674% to 38.442%,compared with the increasing of energy footprint which is from 17.0899% to 47.1852%.The biological capacity has varied from 0.6307 hm2/capital to 0.4443 hm2/capital.The ecological surplus become smaller from 1995 to 2001 with an ecological deficit in 2002 which has went larger year by year. All these show that: Yulin is in a weak unsustainable status.The reasons for the ecological deficits are: the seriously destructed ecology,the overloaded population,and the inefficient utilization of resources and the influence of the changing structure of landuse Then considering the ecological function and the relationship between supplying and demand of natural capital in Yulin,we explore the strategies and measures to accomplish the ecological reconstruction and regional sustainable development in Yulin. |
