汶川地震陕西重灾区地质灾害风险区划探讨
A Discussion on Regional Risk Zoning of Geological Hazard in the Worst-hit Area of the Wenchuan Earthquake in Shaanxi Province
摘要
Abstract
Taking Mianxian County, Lueyang County and Ningqiang County in Shaanxi where were severely hit by the Wenchuan earthquake, as the research object, a preliminary study is made on geo-hazard zoning of Mianxian-Ningqiang-Luryang area, in terms of the international concept of natural hazard, based on 1: 50 000 detailed geological disaster investigation and hazard zoning of geo-hazard and vulnerability zoning of geo-hazard, by use of MAPGIS platform. The result shows that geological hazard risk zoning of Mianxian-Lueyang-Ningqiang area is micro-zoning of geological hazard risk and the geo-hazard risk zoning of Mianxian-Lueyang-Ningqiang area can be divided into 4 levels of risk as high, mediu, low and very low. The area of high and medium risk covers about 60% of the area of Mianxian-Lueyang-Ningqiang, where would be the key areas of geo-hazard prevention in Mianxian-Lueyang-Ningqiang area.关键词
