Land use/cover change analysis in Wuhan city based on RS and GIS

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.
