摘要
提出石漠化土地景观+成因的两级分类模型,根据景观现状进行第一级分类,按石漠化土地的成因类型进行第二级分类,采用“景观+成因”对石漠化土地进行命名。景观分类是利用遥感影像特征解译石漠化强度和分布面积所必不可少的;石漠化土地成因类型与恢复治理模式密切相关,有必要在石漠化土地现状调查时考虑石漠化土地的成因类型。
It is highlighted that the karst rocky deserted land should be classified by landscape and formation genesis in this paper.The authors suggest the landscape as the index of the first category,and the formation genesis as the index of the second category.The first category is necessary to use remote images to interpret the degree and distribution of karst rocky desertification area.The second category is highly correlated with rehabilitation measures.So,in the present investigation of the karst rocky desertification it is necessary to take the formation genesis types into consideration.
