The rapid expansion of construction land is one of the main characteristics of modern land use change in China. Based on the land use database acquired by interpreting the multiple-temporal Land sat Thematic Mapper (TM) images (1995, 2000 and 2005), spatial overlay analysis, spatial-clustering analysis and buffer analysis of GIS were applied and ESI (expansion speed index) and EII (expansion intensity...
We analyzed land use changes and the characteristics of spatial structure in the progress of urbanization from 1991 to 2006, specifically, Huidong County of Guangdong Province. Based on the three temporal Landsat TM images during the study period, land use data of the area were obtained using the maximum likelihood classification method; and the structure of urban spatial development, central, transitional...
Taking Hengshan County; which is located in middle of the north China agro-pastoral transition zone as an example, this paper describes the land use/cover change and land degradation based on TM images received in 1991 and 2002. Data choice and linkage of remote sensing information with geoscientific process was also addressed at the end of the paper
