卫星遥感技术已成为研究地质灾害最有效的方法之一.针对大量的卫星遥感数据源,如何根据研究区特点和研究的目的,选择满足精度要求且经济合理的遥感数据源是值得研究的问题.本文以延安宝塔区为试验区,收集ETM~+、Spot 5、CBERS-02、QuickBird数据,采用相同的波段组合及融合方法进行滑坡灾害解译效果对比研究,定量分析最小可识别图斑和最佳成图比例尺,依据对比结果提出滑坡灾害区划卫星遥感数据的选择原则,为定性、定量区划研究提供依据.%Satellite remote sensing technology has become one of the most effective methods for geo-hazard study. Aiming at plenty of satellite remote sensing data, it has important research meanings to select accurate and economical RS data. In this paper taking Baota district of Yan' an city for example, we collected data of ETM+, Spot 5, CBERS-02, Quickbird, compared of Interpretation effect base on same band combination and fusion methods, analyzed quantitative minimum recognizable graph spots and the best mapping-scale, the selection principle of remote sensing data for geo-hazard zoning according the comparison, the research provides the basis for quantitative and qualitative geo-hazard zoning.
