| Abstract: | Ecological security is an important constraint for regional sustainable development.Base on the theory of ecological footprint,taking Yanchi County as a case,we assessed the ecological security situation in this area.The results indicated that the county's present ecological footprint is 3.68hm2 per capita and the biological capacity is 1.74hm2 per capita.In the past 10 years,due to the rapid economic growth and the acceleration of urbanization process,there is an obvious increase on ecological footprint.Ho... |
