【摘要】 为在目前地质灾害调查、评估的生产和实践中推广GIS技术的应用,结合"十一五"规划科技支撑计划课题《地质灾害风险评估技术研究》的工作和汶川地震重灾区灾后重建规划资源与环境承载力评价中利用ArcGIS实现快速应急制图的实践,在阐述滑坡风险制图的基本类型:滑坡编录图、滑坡易发程度分区图、滑坡危险性分区图、滑坡风险区划图的基础上,重点阐述利用ArcGIS软件及其空间数据建模方法,实现滑坡风险制图过程中的基础数据信息获取、处理和利用空间数据模拟工具(SDM)开展滑坡快速制图的流程与技术方法。更多还原

【Abstract】 In order to popularize the application of the GIS technique in the present geohazard investigation and assessments, the ArcGIS is used to achieve rapid, urgent map making in the subject"Technical Research in Geohazard Risk Assessments"of the Science and Technology Support Plan of the eleventh Five-Year Plan and the assessments of the bearing capacity of resource and environment for post-hazard reconstruction program in worst-hit areas of the Wenchuan earthquake.The basic types of landslide risk maps include the landslide documentation map, landslide vulnerability zoning map, landslide danger zoning map and landslide risk zoning map.Based on a description of these map types, the focus is put on the method of modeling by using the ArcGIS software and its space data in order to achieve basic information acquisition and processing in the landslide risk map making and use the spatial data modeling tool to carry out rapid landslide map making.更多还原
