兖济滕矿区地表塌陷遥感信息解译研究

Extracting of Remote Sensing Information of Mining Subsiding in Yanjiteng Area

采矿塌陷地的动态监测是矿区资源管理的重要方面,从遥感图像中提取采矿塌陷地是遥感应用于矿山资源环境监测的重要研究课题。根据兖济滕地区的各种塌陷地的特点,充分利用光谱特征、地学特征等信息,采用了波段阈值法、地理信息系统、模型法以及监督分类法等技术方法,建立了研究区塌陷动提取的技术体系。并对研究区进行遥感图像处理与专题信息提取,有效完成对兖济滕矿区塌陷地信息的提取和评价。

It is one important aspect of RS （remote sensing） applications in mining areas to extract mining subsiding land from RS images. Taking the Yanjiteng area as the study case and using TM image data, pose the technique of extracting subsiding information on the basis of spectrum characteristic of all subsiding types. Firstly, compartmentalize the research area into multi-layer according to the distributing of every type in the area. By using the techniques of band threshold, GIS, modeling and supervision classification, information of mining subsiding in Yanjiteng area is extracted more precise and effective then traditional method.
