valuation of ecological pressure for the resource-based and heavy industrial city-a case study of Fushun, China

摘要

The ecological pressure indicator system of the resource-based and heavy industrial city was established, and the weight of each index was calculated by factor analysis. A case study of Fushun city was introduced. The developing status of ecological pressure during 2000-2009 was analyzed and assessed. Based on these, the relationship between per capita GDP and ecological pressure was validated by software SPSS. Results indicated that the ecological pressure index increased from 0.82 to 0.88, and it demonstrated an increasing trend on the whole. The index was steady during 2000-2004, but revealed obvious fluctuations during 2004-2009. Degree of fitting between per capita GDP and ecological pressure was higher, and R square was 0.917. Environmental pollution resulting from socio-economic development is still the main cause of ecological pressure.
