应用 2 0 0 0年TM影像资料及典型地区TM 7个波段数据 ,在ARCVIEW和ENVI平台上进行解译 ,并参考其他相关资料及图件 ,对贵州喀斯特山区石漠化现状进行调查 ,结果表明 ,贵州喀斯特山区中度以上石漠化面积占全省总面积的 7 5 % ,轻度以上石漠化面积占全省总面积的 2 0 4%。从分布上看 ,石漠化土地更多地分布在纯碳酸盐岩为主的贵州西部、西南部
Based on TM image data of 2000 and TM 7 band data of typical areas, interpretations are made on ARCVIEW and ENVI platforms, and other relevant data and maps are used to investigate the status quo of rocky desertification in Guizhou Karst Mountains. The results show that The karst rocky desertification area in Guizhou Karst mountains accounts for 75% of the total area of the province, and the lightly above rocky desertification area accounts for 20% of the total area of the province. From the point of view of distribution, the rocky desertification land is more distributed in western Guizhou and southwestern Guizhou, which are mainly pure carbonates
