中文摘要	以贵州省2010年石漠化程度分布与土壤类型分布图为基础,运用地图代数原理,通过计算二者的转移矩阵,从而得出不同石漠化程度下土壤类型的空间分布情况,并探讨研究区石漠化背景下,土壤类型与石漠化的空间分布规律,分析石漠化的发生、分布与土壤类型的相关关系。其结果表明:喀斯特地区石质土的石漠化发生率最高达到46.41%,其次为黄棕壤的43.32%,综合排序为石质土>黄棕壤>山地草甸土>棕壤>红壤>粗骨土>石灰土>黄壤>紫色土>水稻土>潮土;分等级讨论时以中度石漠化为主导,且石质土的中度石漠化发生率最高,达到了21.68%。石漠化程度的空间分布在不同土壤类型中存在着明显差异,并且二者之间有一定联系,土壤本身的性质差异是重要的因素之一。
英文摘要	This paper takes Guizhou Province,a typical representative of karst landforms in southwest China, as the research object.Guizhou Province is located in the southeastern part of southwest China,and the eastern part of Yunnan-Guizhou Plateau.The landform is dominated by plateau mountains,and its topography is high in the west and low in the east.It is inclined from the central to the north,east and south,and the structure is distributed in three steps distribution.The average elevation is about 1,100 m,the climate is warm and humid.It belongs to the subtropical humid monsoon climate with an average annual temperature of 14-18℃and an annual average precipitation of 1,100-1,300 mm. In this paper,by referring to the study of rocky desertification by relevant scholars,the degree of rocky desertification was divided into 5 grades,namely,non-rocky desertification,mild rocky desertification,moderate rocky desertification,severe rocky desertification and extremely severe rocky desertification.Then,the spatial distribution map of rocky desertification in Guizhou in 2010 was obtained.The soil type map of Guizhou soil chronicle was vectorized in ArcGIS,and finally a digital map of soil type distribution was obtained by thematic mapping.The spatial correlation between karst rocky desertification and soil types in Guizhou Province was quantitatively analyzed by using spatial analysis function,combined with the principle of map algebra,and the transformation matrix,combined with slope,elevation and other information,so as to provide scientific basis for the prevention and control of rocky desertification in different soil types.
