Study on Ecological Security of Resource-Based City Based on Ecological Footprint Theory
Based on theory and method of ecological footprint, this paper adopted ecological pressure index, ecological occupation index and ecological economy coordination index as evaluation indexes of regional ecological security. Then the paper constructed grade classification standard of ecological security and developed a case study on Yima city from 2001 to 2010. The results show that per capita ecological footprint of Yima increases from 1.1691 hectares to 3.9249 hectares, per capita ecological capacity decreases from 0.8112 hectares to 0.4886 hectares, while per capita ecological deficit increases from 0.3579 hectares to 3.4363 hectares. At the same time, ecological security indexes of Yima are in a bad level. The results reveal that the structure and functions of the eco-economic system of Yima city should be adjusted. The study can provide references for urban ecological management and environmental planning of concerned management departments.
