影响地震救灾效率的因素分析——以汶川8.0级地震和玉树7.1级地震为例
Analysis of the Factors Affecting the Efficiency of Earthquake Disaster Relief——A case study on Wenchuan M8.0 earthquake and Yushu M7.1 earthquake
摘要
Abstract
The relief efficiency is defined as an increasing death toll relative to missing persons during a certain period after an earthquake. A series of death toll of 34 significant earthquakes all over the world in recent 20 years are collected, and the correlations between relief efficiency and death toll, magnitude, intensity, per capita GDP, population density and time at maximum relief efficiency, are analyzed. We found that death toll in earthquake is the main factor controlling the relief efficiency, and the significantly negative correlations between relief efficiency and earthquake magnitude, and occurring time of maximum efficiency are shown, implying that the rapid emergence response of a government after a catastrophe will increase disaster relief efficiency. A simulation equation (r2 =0. 82) to calculate the relief efficiency is figured out by filtering and reducing noise. Finally, the relief efficiency of two catastrophes, Wenchuan M8. 0 earthquake in 2008 and Yushu M7. 1 Earthquake in 2010, is compared. It shows that the per capita relief efficiency of Yushu Earthquake is greatly improved relative to that of the Wenchuan earthquake.关键词
