Abstract:: In order to better optimize and allocate land resources reasonably, this paper took land use data of Fugu County in Shaanxi Province in 2010 to analyze the quantitative characteristic of land use in Fugu County by combining the software like ArcGIS, Fragstats, etc. with the method of mathematical model analysis, and on the basis, introduce terrain niche index and landscape pattern index to analyze the land use spatial distribution characteristics of various land use types. The results show that the land resource type in Fugu County is relatively complete, grassland, cultivated land and woodland are the main landscape types, the proportion of area of the three types of land in the county is 57.74%, 24.50% and 12.12%, respectively, the combinational number of land use types is relatively small, regional differences of land use are significant; view from the spatial distribution pattern, the connection degree of woodland, grassland, cultivated land and water is relatively higher, patchy distribution; the spatial distribution of urban and rural construction land is scattered, patch shape is complex, the aggregation degree is relatively lower, fragmentation degree is higher. The results show that the method combining land use spatial quantitative structure with spatial pattern analysis can be used in the regions of complex terrain.
