【 摘 要 】

Xiangxi Region is on the edge of Yunnan-Guizhou Plateau which has complicated topography. It is a multi-nationality region which is the important protected area for resources and environment in China. Based on the data of Landsat TM/ETM image in 1990, 1995, 2000, 2005, 2010 and 2015, the change of landscape pattern in Xiangxi Region was analyzed by the use of ARCGIS and FRAGSTATS. The results showed that: (1)The area of farmland and forestland decreased. (2)The landscape patches in Xiangxi Region tended to be more fragmented and diversified but the shape of patches were more simple. (3)The fragmentation of farmland, building land and unused land was more serious. The patch shape of building land, water and wetland is more complicated. (4)These changes may be caused by the policy of grain for green and urban expansion. This study provides a strong theoretical basis for policy-making of environmental protection and management in Xiangxi Region of Hunan Province in China.
