With the use of MSS and TM data of Shenzhen in 1980,1988 and 1994,land use/cover map was compiled.The paper analyzes the temporal spatial regulation of land use/cover change during the last 20 years followed by the analysis of the correspondence relationship between the land use change and the urban environmental security. The results show that the land use/cover change is the key factor accountable for the rapid urbanization process;urbanization aggravated the urban flooding and the soil erosion;the spatial difference of the environmental pollution of the research area presents the obvious positive correlation with the proportion of the corresponding urban land,whose significant coefficient can reach 0 001.Hence,rehabilitation of the vegetation has the unsubstituted function on reducing the citys eco environmental problem in the urbanization process.
