THE RS-AND GIS-BASED SPATIOTEMPORAL ANALYSIS ON LAND USE CHANGES IN FUSHUN, LIAONING PROVINCE

The RS and GIS technology and landscape index method are adopted to study the landscape characters and their dynamic changes of Fushun, Liaoning Province in 1998 and 2005. The results indicate that, from 1998 to 2005, the acreage of shrubbery and dry land decreased, while the continuity of woodland and shrubbery increased. In regard to the landscape level, the SHDI (Shannon-Wiener Diversity Index), SHEI (Shannon-Wiener Evenness Index) and FRAC (Fractal Dimension) of land increased, but the Dominance, Contagion and AI (Aggregation Index) of land decreased. About patch level, the FRAC of all patch types, but shrubbery and woodland, increased, and the AI of all patch types except woodland decreased. The whole landscape therefore shows a trend of fragmentation.
