高寒干旱地区环境遥感信息提取方法研究

根据高寒干旱地区环境研究的特点，研究了适合于遥感信息提取的区域环境综合分类系统，提出了利用现有成熟的图像分类和专题信息提取的技术方法，在ＧＩＳ的支持下实现了多种遥感信息与非遥感信息的复合。利用多重判据在ＧＩＳ环境下，通过基于知识的识别和修改，对初分类结果中相混淆异类进行了有效分离，达到类型纯化

Extraction of Remote Sensing Information of Environment in High Tundra and Arid Area

According to the features of environmental research in high tundra and arid area,a regional comprehensive environmental classification system is built,which is adapted to the extraction of remote sensing information.The main objective of this paper is to introduce a new method for extracting remote sensing information of environment.Firstly,using the common methods for remote sensing classification and information extraction,the environmental information is extracted.Then the merging of remote sensing with comprehensive various information is realized in GIS.Through knowledge|based reclassification and modify in GIS,the primary accurate of classification results is improved efficiently.The method is an efficient way to extract environment information in high tundra and arid area.
