Abstract

Taking the year 1979, 2008 and 2010 as the representative reference periods, the vulnerabilities and loss risks of hazard-affected bodies from Wenchuan Earthquake-induced geohazard-chain and its temporal-spatial changes in Qingping country have been analyzed mainly through GIS, high-resolution remote sensing-based method and scenario analytical method. The main achievements are concluded as follows: From 1979 to 2010, the building area increased 2.4 times, the road mileage grew more than 2 times but the farmland area reduced by 40.7%. Under the scenario of Wenchuan Earthquake-induced geohazard-chain, in the last thirty years, the damaged building area increased 2.7 times, the mileage of destroyed road grew 1.9 times but the ruined farmland decreased by 62.6%. The economic losses of the three kinds of hazard-affected bodies in 2010 were 4.41 times more than that in 1979. Urbanization, population growth and economic development are the main driving forces of the temporal-spatial changes of the risk from earthquake-induced geohazard-chain in Qingping country.
