基于GIS地震灾害的模型研究和空间分析

摘要

The spatial analysis model building damage prediction,seismic risk analysis model,earthquake prediction model of economic losses,and casualties and homeless forecast models such as seismic lines is described.Based on building damage prediction,a new GIS system for earthquake damage prediction method for building a fuzzy damage index is presented to build damage prediction. A case of Wenchuan earthquake in Sichuan province is also to introduced to study the earthquake model and spatial analysis,supplying advance sciencetific evidence for decision-making sectors to the earth damage and post-disaster reconstruction.%系统地介绍了建筑物震害预测空间分析模型、地震危险性分析模型、地震经济损失预测模型、人员伤亡与无家可归人员预测、等震线模型等,对建筑物震害预测提出了一种新的、适用于GIS系统的建筑物震害预测方法——模糊震害指数法。并以汶川地震为例进行了地震模型研究和空间分析,为决策部门对震后受损状况与灾后重建工作提供科学依据。
