Abstract:
Based on the residents′ income and expenses data and statistical urban environmental data of Xi′an city nearly 20 years, through ARCGIS spatial analysis technology and the multistage fuzzy comprehensive evaluation model, with urban internal microscopic areas (streets) as the carrier, the spatio-temporal coupling and evolution rule of urban poverty and environment are analyzed. The results show the urban poverty structure changed from radial distribution of nested to layers distribution, the degree of urban poverty reduced continuously; the comprehensive environmental quality in suburb was better than that in the centre, but the integrated environmental quality became worse gradually in the whole city, especially in the southern region; the coupling of urban poverty and comprehensive environmental quality changed and did not present some unified rules, but it showed a more refined coupling characteristic in the inner.
