锡林郭勒草原景观多样性的空间变化

本研究将遥感应用，地理信息系统（ＧＩＳ）和景观空间分析模型相结合，以植被类型做为景观划分基础，计算并比较了锡林郭勒草原多样性的空间分布特征，结果表明，在草甸草原－典型草原－荒漠草原这一区域尺度上，景观多样性以典型草原区最高，草甸草原区次之，荒漠草原区最小，进一步分析景观多样性与生境多样性的关系，得出景观多样性与气候多样性，地貌多样性的线性中具有相应的适应性，反映出景观多样的形成的是多个生态因子综合

The Spatial Changes of Landscape Diversity in Xilinguole Steppe

By the combination of remote sensing application,GIS and spatial analysis model of landscape,this research determined and analysised the spatial distribution characteristics of landscape diversity in Xilinguole steppe,which showed that the landscape diversity in typical steppe rigion was the highest,the value in meadow steppe was the second and that in desert steppe was the lowest.This kind of distribution was corresponding with the linary piling up of climat diversity and geomorphology diversity,which reflected that the landscape diversity was the result of synthetic action of different ecological factors.
