应用１９８０、１９８８、１９９４年的ＭＳＳ、ＴＭ资料,编制了相应时期深圳市土地利用／覆盖图,分析了近２０年来深圳市土地利用变化的时空分异规律。在此基础上,分析了土地利用变化与城市生态环境安全水平的关系。研究结果表明,深圳快速的城市化过程是引起土地利用变化的主要原因；土地利用中城镇用地的增加导致城市洪水的加剧和水土流失的增加；以乡镇为单元的环境污染的空间差异与对应区域城镇用地比例的大小呈明显的正相关关系,显著性水平达到０－００１,由此认为,在城市化过程中,确保相当数量的绿地对缓解城市生态环境问题有着不可替代的作用。

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.
