晋中市土地利用变化特征研究

Study on the Characteristics of Land Use Change in Jinzhong City

根据晋中市1996-2004年土地利用数据资料,分析了该市土地利用的变化特征。结果表明:(1)耕地、牧草地、其它农用地和水利设施用地数量减少,林地、园地、居民点及工矿用地、交通运输用地和未利用地数量增加,其它土地数量没有变化,牧草地数量变化最大。(2)各类用地单一动态度由大到小的顺序是牧草地、交通运输用地、未利用土地、其它农用地、林地、居民点工矿用地、耕地、园地、水利设施用地、其它土地。(3)各类用地相对动态度区域差异性程度存在显著差别,牧草地的相对动态度区域差异性最大,耕地的相对动态度区域差异性最小。

Based on the data of land use from 1996 to 2004 in Jinzhong city,the characteristics of land use change in the district were analyzed.

Grassland was the land use type of most spatial variety of relative land use change degree. Cultivated land had the least spatial variety of relative land use change degree.
