MAO Xian-cheng et al(College of Geo-science and Environment Engineering,Central South University,Changsha,Hunan 410083)  
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.
