基于GIS的泥石流发生域危险性评价——以大寨沟流域为例
- Title:
- Risk Assessment of Debris Flow Range Based on GIS——Take Dazhaigou Valley as an Example
- Keywords:
- debris flow range; risk assessment; the assessment indexes system; GIS

- 摘要:
- 以大寨沟流域为例，在GIS技术支持下，通过计算机对空间数据获取、处理和分析，建立了该流域的泥石流发生域危险性评价基本数据库。再通过合理选取评价指标、建立指标权重体系、计算综合评价值等一系列程序，建立了泥石流发生域危险性评价的数字环境模型，绘制了大寨沟流域泥石流发生域危险性等级评价图。在GIS技术支持下，实现了大寨沟流域泥石流发生域的危险程度评价，为白鹤滩水电站的顺利建设打下了基础。
- Abstract:
- Take Dazhaigou valley for example, special data are collected, disposed and analyzed by cpmputer.The basic database of the risk assessment of debris flow range are established based on GIS.After adopting proper appraisable indexes and confirming indexes weight, synthetical appraising value was computed, the digital environmental model of the risk assessment of debris flow and the risk grade diagram of criticality assessment of debris flow range in Dazhaigou valley are established.Under the GIS technique support, the risk assessment of debris flow range in Dazhaigou valley is accomplished.
