1950－2013年我国洪涝灾情时空特征分析
The Distribution of Flood Disaster Loss during 1950-2013
摘要
Abstract
It has important practical significance to study the temporal and spatial distribution characteristics of flood disaster for effective flood control and disaster reduction.Through analyzing the historical disaster loss data, we find that the crops affected area and economic loss show a rising trend,the death tolls of population show a trend of decline during 1950-2013 in provincial level.In the space scale,the disaster loss of the East China is more than West China,and of South China is bigger than North China.Meanwhile,the flood disaster severity shows a decrea-sing trend during 1990-2013.And at provincial level,the annual disaster severity of the southern provinces of Chi-na is higher than the north area,but in recent years,showing a trend of South China decreasing and North China increasing.关键词
