Abstract:: Land system has become one of hot spots for the global environmental change researches, as is the closest to the natural environment and the human system cross. Quantitatively measuring the structure of land utilization is conducive to the understanding of the use and changes of land system. We used the ArcGIS software, the second national survey of land use data of 1:10 000 scale for Jiangkou County, Yinjiang County, and Songtao County in Tongren City, Guizhou Province in 2009 for the research of basic data and the second survey classification to divide classes into construction land, cultivated land, woodland, grassland, waterbody and unused land based on the landscape pattern index, fractal dimension and stability index for measuring index, We analyzed the land use spatial structure of the land around the Fanjing Mountain Tourism Economic Zone composed of Jiangkou County, Yinjiang County and Songtao County. The results show that the type of the land use in this area has a landscape structure model for woodland as matrix, cultivated land, construction land, grassland, unused land as plaque inlaid structure, and with water and road for linear corridor from the landscape ecological sense of scale. In all types of landscape patches, forest landscape types occupy the dominant position and with respect to forest land, the other classes of plaque are relatively broken, and dispersed and distributed spatially and the diversity of land scape is not high. The overall level of stability of spatial structure of land utilization is not high. And the ecological system is fragile.
