摘  要:
利用GIS技术和数理统计分析方法,借助土地利用变化指数模型,定量分析了山西省怀仁县1989年第一次土地调查至2009年第二次土地调查的土地利用变化时空特征。研究表明,怀仁县土地利用类型以耕地、林地、草地为主;林地、交通运输用地、城镇村及工矿用地大幅度增加,耕地、其他土地大幅度减少;同时,土地利用数量变化存在明显的区域差异。综合分析表明,人口、经济、政策在土地利用变化中起着主导作用。

摘  要:
Supported by Geographic Information System(GIS) and mathematical statistics methods,the temporal-spatial characteristics of land use changes from the first land survey in 1989 to the second in 2009 in Huairen County of Shanxi Province were analyzed quantitatively by using a land use change index model.It was showed that cultivated land,forest land,and grass land took a large proportion of total land area in Huairen County.It was also showed that the area of forest land,traffic land and residential area in this region increased greatly,while cultivated land and other types decreased greatly.Moreover,there were obvious spatial differences in land use changes.From the analysis we could see that the population,economy and policy factors played a crucial role in land use change in Huairen County.
