A Simulation Study on Eco-environmental Effects of Urbanization Using Responsive Model

Urbanization is a main trend of social-economic development all over the world. But with the scale of urbanization enlarged and the human development intensified, a large scale of infrastructure construction and industry development has given rise to pressures on regional eco-environment for high material consumption and heavy pollution. This paper has taken Jiangxi province as a case and has the application analysis made. Through calculating the comprehensive level of urbanization by means of principle component analysis (PCA) method and comprehensive quality of eco-environment with analytical hierarchy process (AHP) and fuzzy membership representations (FMR), the paper puts forward response degree model (RDM) and comprehensive response degree model (CRD) by using the economic elasticity function and analyzes the temporal response characteristics and total response intensity of eco-environment to urbanization from 1978-2005 in Jiangxi province. The results reveal that there doesn’t exist corresponding relationship between the urbanization process and eco-environment changing, which concerns with not only urbanized itself advancement pattern, but also the ecological environment construction and protection way.
