摘 要：
为了揭示喀斯特高原山区的潜在石漠化景观格局变化现状和探寻地形因子对潜在石漠化景观格局变化的影响程度,选取了位于贵州省普定县的后寨河流域中下游作为研究区,利用地理信息系统软件,解译出研究区1973年和2004年的潜在石漠化分布图,分析潜在石漠化的进程;利用相关分析法对海拔、坡度、坡向和坡位等地形因子对潜在石漠化景观格局变化的影响程度进行了定量分析。结果显示:从1973～2004年,潜在石漠化景观格局发生变化,且其在空间上呈不均匀状态;地形因子对潜在石漠化景观格局变化存在明显的影响,不同的地形因子对不同类型的潜在石漠化景观斑块的影响程度不同。

摘 要：
In order to reveal the change of Karst rocky desertification landscape pattern and find out the relationship between those topographical factors and rocky desertification landscape pattern change,Houzhai stream in Puding county was chosen as study area.With the support of GIS softwares,distribution maps of Karst rocky desertification in 1973 and 2004 were made for rocky desertification landscape pattern change analysis.Correlation between topographical factors and rocky desertification landscape pattern change was analysed quantitively by using correlational analysis method in Excel.The results indicated that rocky desertification landscape pattern changed unevenly in the study area from 1973 to 2004,topographical factors influenced rocky desertification landscape pattern change obviously,and different topographical factors influenced different rocky desertification landscape patches in different degrees.
