Abstract

The land use/cover change is a frontier subject in the research area of the current global environmental change. Typical regional LUCC case study is an important way to recognize of global change. Land use/cover change temporal and spatial detection process is that accumulates space-time continuum of land use / cover data, then establishes the multi-source space-time data platform of LUCC. The space-time distribution rules of LUCC are researched on that data platform based on RS and GIS. This study area is located in Wuhan city, using interpretation results of the TM image of Landsat 5 in 1996 and 2006. It takes a quantitative research on Land Use / Cover Change in Wuhan city based spatial analysis of GIS and methods of mathematical statistics in 1996–2006. The results show that:(1) General characteristics of land use/ cover show that cropland, grassland and unused land have decreased, forest, water and construction land area have increased in Wuhan city from 1996 to 2006; (2) These three kinds of changes of cultivated land into forest land, construction land and water which distribution are the most widely, and conversion rate is the largest in the 10 years.

基于RS和GIS的武汉市土地利用/覆被变化分析

土地利用/覆被变化是当前全球环境变化研究领域的一个前沿课题。区域土地利用变化典型案例研究是认识全球变化的重要途径。土地利用/覆被变化时空检测过程是累积土地利用/覆被数据的时空连续体，进而建立土地利用/覆被变化多源时空数据平台。在基于RS和GIS的数据平台上，研究了土地利用变化的时空分布规律。研究区位于武汉市，利用1996年和2006年Landsat 5卫星TM影像解译结果。基于GIS空间分析和数理统计方法，对1996—2006年武汉市土地利用/覆被变化进行了定量研究。结果表明:①1996—2006年，武汉市土地利用/覆被总体特征显示，耕地、草地和未利用地面积减少，森林、水域和建设用地面积增加;(2) 10年间耕地向林地、建设用地和水域的转变分布最广，转化率最大。
