| 摘 要： | 在构筑1：50万贵州岩溶地区岩石组合类型分布图的基础上,以GIS为分析手段,对贵州省石漠化分布图和地层岩性图进行了空间分析,探讨了各类岩性与不同级别石漠化之间的相关关系。石漠化与岩性具有明显的相关性,强度石漠化主要分布在纯质碳酸盐岩地区,尤其是纯质灰岩地区;中度石漠化在白云岩组合中的比例较灰岩组合中高;轻度石漠化在碳酸盐岩与碎屑岩夹层和互层中分布较广;石漠化与纯碳酸盐岩相关关系最明显。 |

| Abstract: | Based on 1:500,000 digital map of lithology distribution in Guizhou, spatial analysis of the maps of rock desertification and of lithology is conducted by GIS. Results indicate that there is obvious relativity between rock desertification and lithology. Intense rock desertification scatters maily in pure carbonate rock area, especially in pure limestone area whereas moderate rock desertification is more widely distributed in dolomite association than in limestone association and slight rock desertification is widely distributed in carbonate rock association layered with clastic rock. |
| Keywords: | rock desertification lithology spatial correlation karst region Guizhou |
