摘要
地质灾害危险性评估是工程建设中对建设用地进行灾害活动程度及破坏损失情况进行评定估算的重要工作,是保障人民生命和财产安全的重要手段。探讨基于GIS技术对云南省师宗县人民医院建设项目评估区基础数据进行预处理、确定地质灾害影响因子及对其赋予相应的权重、建立空间叠加模型并对评估区地质灾害危险性进行分区处理,实现了基于GIS技术的云南省师宗县人民医院建设项目用地地质灾害危险性评估。研究成果为云南省师宗县人民医院建设项目地质灾害危险性评估提供了强劲的技术支撑,对其它建设项目地质灾害危险性评估具有推广应用意义。
Geohazard danger evaluation is not only very important in construction projects,but also an essential measures to protect people＇s lives and property,which evaluates land loss and damage degree of Geohazard danger activity.This paper realizes the research about land Geohazard danger evaluation of the construction project of people＇s hospital in Shizong County,Yunnan Province,by preprocessing basic data about evaluation area,determining the impact facts and giving them the corresponding weights,and building space superposition model to evaluate geohazard danger of study area on divisional processing.All of these processes are based on GIS technology.The research result provides powerful technical support for land geohazard danger evaluation of the construction project of people＇s hospital in Shizong county,and has practical application meanings for geohazard danger evaluation of other construction projects.
