为解决好贵州长江、珠江两大流域的生态环境问题，利用贵州省遥感影像，在3S 平台上获取研究区喀斯特石漠化图，分析贵州省境内长江流域和珠江流域石漠化动态演变。结果表明：2010年，长江流域石漠化面积21955．11 km2，珠江流域石漠化面积14517．42 km2，长江流域石漠化比例及石漠化强度（中度＋强度）均小于珠江流域；2005-2010年，长江流域石漠化面积以年均0．04百分点速度减少，而珠江流域石漠化面积以年均0．30百分点速度减少，石漠化发展趋势得到遏制，等级程度降低与区域生态环境治理有一定的相关性。

The dynamic evolution of rocky desertification in the Yangtze river basin and Pearl river basin in Guizhou was analyzed according to remote sensing image and karst rocky desertification map obtained through3S platform to solve the ecotype problem in the Yangtze river basin and Pearl river basin in Guizhou.The result shows there was 21 955.11 km2 rocky desertification in the Yangtze river basin and 14517.42km2 rocky desertification in the Pearl river basin.The area ratio of rocky desertification in the Yangtze river basin is lower than in the Pearl river basin.From 2005 to 2010,the area of rocky desertification reduced at the rate of 0.04 percentage points per year in the Yangtze river basin and 0.3 percentage points per year in the Pearl river basin.The growing trend of rocky desertification was restrained.The degree of rocky desertification reduce had certain correlation with the regional ecological environment governance project.
