摘　　要：农牧交错带牧区土地利用方式变化关系到农牧交错带草原生态环境的稳定和区域土地资源的可持续利用,对其研究具有重要的现实意义.根据1997-2006年内蒙古自治区四子王旗土地利用变更调查数据,运用土地动态度和土地利用结构信息熵模型,对其近10年的土地利用变化过程进行研究.结果表明,近10年四子王旗大部分土地类型面积发生了变化;旱地的减少量最大,减少了56 445.4 hm2,未成林造林地的增加量最大,增加了77 287.1 hm2,菜地的年平均变化率最大,年增加率达39.59%,人工草地、独立工矿用地、荒草地均有所增加;土地利用结构信息熵逐年上升,说明四子王旗土地利用系统日趋无序.The change of the way of land use is related with the plain environment and the region sustainable use of land resources in the farming-pastoral transitional zone. Based on a detailed investigation on the data of the change of land use during 1997--2006,the land change process in nearly a decade was studied in Siziwangqi by applying land dynamic degree model and the information entropy model of land use structure. The results showed that the land use types in most areas of the Siziwangqi have changed. Dry land decreases quickly and has reduced 56 445.4 hmz ; immature woodland increases quickly and has added up by 77 287.1 hm^2. The annual average change rate of vegetable land is the biggest,arriving at 39.59%. The human-made grassland,mine land and barren are increasing annually. The information entropy of the land use structure increased gradually in the past decade in Siziwangqi,implying that the land use system tends to be in disorder.
