| 摘 要： | 通过比较应用多种植被指数方法增强石漠化信息的不同效果试验,采用增强植被指数（EVI）提取石漠化信息,并利用mapgis6.x平台上开发的国产遥感解译软件进行人-机交互分类解译,野外验证表明,准确率达到89%。石漠化提取结果表明,石漠化易发生在相对高差大的峰林洼地、峰丛洼地和岩溶断陷盆地中,其发生率分别达42%、35%和44%。

| Abstract: | Different effects of enhancing the rocky desertification by many vegetation index methods were compared.The information of rocky desertification was extracted by using enhanced vegetation index(EVI) method.Using the national remote sensing interpretation software developed on mapgis6.x platform,the human-machine interactive classified interpretation was made.The field survey showed that a preciseness ratio reached 89%.It showed that rocky desertification occurred easily in karst landform such as karst tecto... |
