应用多阶抽样解译法从遥感图像上提取土地类型信息——以内蒙古准格尔旗皇甫川流域为例

Extracting of Land Type Information from RemotelySensed Imagery Using the Multi—level Sampling Interpretation Approach---A Case Study of the Huangpuchuan River catchment in Zhuogeer County of Inner—Mongolia

以内蒙古准格尔旗皇甫川流域为例,探讨如何应用多阶抽样解译法(multi—level sampling interpretation)从遥感图像上提取土地类型信息。使用这种方法划分出了研究区的三级土地类型,即土地系统、土地单元和土地点。

This paper deals with the application of the multi—level sampling interpretation approach of land type information from remotely sensed imagery taking the Huangpuchuan River catchment in Zhuogeer County of Inner—Mongolia as an example. Based on this approach three levels of land type,i, e. land system, land unit and land site, were delineated in the study area.
