随着第二次全国土地调查成果的完成，区域土地利用结构研究对新一轮土地利用总体规划的编制意义重大。以四川梓潼县为例，采用景观结构指数与GIS空间分析技术相结合的方法，探讨县级尺度土地利用结构的空间分异特征。研究结果表明：（1）研究区土地利用数量结构空间分异十分明显，土地利用多样化和土地利用组合类型数整体水平较高，且平坝丘陵区与丘陵山地区差异明显；土地利用的集中程度则刚好相反，与多样化呈显著负相关；土地利用类型区位熵空间分异明显，耕地区位熵优势在西部乡镇，园地区位熵优势位于中部乡镇，林地区位熵优势位于东部乡镇。（2）空间格局分异总体水平较高，且从西部平坝丘陵到东部丘陵山地差异明显，土地利用景观格局破碎度由强变弱，土地利用类型多样性由复杂到简单；土地利用优势度由低变高；土地利用均匀度由高变低。

With the results of the second national land survey completion, the new round of regulations for the preparation of the overall land use plan landscape ecology, landscape structure indices and GIS technology taking regional land use structure of is of great significance. Using Zitong County, Sichuan Province, for example, this paper studied the spatial variation of land use structure in Northwest Sichuan hilly area. The results show that：（ 1 ） The number of land use structure of spatial variation＇is clear, land-use type of diversification and the overall land use mix high level and hilly areas and hilly Pingba is significantly different from mountain areas; land-use concentration is just the opposite, and the diversity is sig- nificantly negatively correlated; land use spatial variation of location quotient has obvious advantages of lo- cation quotient arable land in the western townships, park areas of our strengths in the central town entro- py, entropy advantage of forest areas of our towns in the east. （2） The spatial pattern of the higher overall level of differentiation, and the hills to the east from the western hills and mountains Pingba are significantly different, landscape fragmentation, land use change from strong to weak, diversity of land use types from the complex to simple; land dominance from low to high; land use from high to low uniformity.
