摘　　要：黄土高原地区地质灾害多发频发,危害严重,应用亚米级的高分二号(GF-2)卫星影像数据,提取地质灾害信息,并对室内解译结果进行了野外查证。本文提出了以GF-2卫星数据为主要信息源,进行地质灾害解译的技术方案;并以宁夏南部黄土高原区为例,验证了该方法的适用性,为规模化地开展基于国产高分系列卫星的黄土高原地区地质灾害遥感解译提供了可行的技术方案;通过GF-2卫星影像与常用的国内外卫星数据用于地质灾害信息判释的对比研究,认为GF-2卫星影像对于地质灾害信息的识别能够满足地质灾害遥感解译的要求,GF-2卫星影像的应用具有较高的性价比和显著的经济社会效益。The geological hazards in the loess plateau are frequent and serious .Using the submitter GF-2 satellite images , We derive geological hazard information and conducted field verification .The author proposed a technical method of the geological disaster inter-pretation, taking the GF-2 satellite data as the main information source .In the loess region of Southern Ningxia as an example , Veri-fy the applicability of the method , To provide feasible technical scheme for large -scale development of the remote sensing interpreta-tion of geological hazards based on the domestic high score satellite on loess plateau .It has certain popularization and application val-ue.A comparative study on the application of GF -2 satellite images and the commonly used domestic and foreign satellite data in the interpretation of geological hazard information , In the aspect of the identification of geological hazard information , the GF-2 satellite images can meet the requirements of remote sensing interpretation of geological disasters .It is significant economic and social benefits .
