摘　　要：介绍了基于虚拟GIS和空间分析技术在小流域泥石流地质灾害遥感解译中的方法及其应用,提出了基于数字高程模型(DEM)、遥感影像和各类地质环境要素创建遥感解译环境,并以嵊州市小流域泥石流地质灾害调查与评价项目为例,阐述了小流域泥石流调查分级、泥石流沟谷与地质环境要素提取等工作的技术方案。该方案有效地改善了遥感解译环境,提高了解译精度与工作效率,获得了丰富的地质环境信息,成为区域性泥石流调查的有效手段。The remote sensing and the GIS technology have been widely applied to the geological disaster investigation and assessment. This paper presents the remote sensing interpretation method with debris flow disaster based on virtual GIS and spatial analysis within small-water-basin. It proposes some technical plans such as the creation of remote sensing interpretation environment based on DEM, remote sensing im- age and all kinds of geological environment elements, and the abstraction of debris flow valley＇s shape and geological environment elements. Finally, it expounds the application achievements with Shengzhou County as the example.
