摘要
沿海地区作为人口积聚、国民经济和社会发展的重要区域和战略中心,在台风灾害中遭受的损失往往是惨重和致命的,所以亟待开展沿海地区台风灾害损失评估研究。根据1990-2007年的台风灾情资料,选取代表性指标尝试构建了台风灾情评估模型,并对沿海省市的台风灾害损失及其与致灾因子的关系进行分析评价。结果显示:除个别区域外,沿海地区台风灾害损失都呈下降趋势,但各区域下降的幅度不等,其中浙江省、江苏省和海南省下降幅度较低,均不足10%;浙江省、福建省和广东省18年间平均台风灾害损失较大;上海市以南各区域台风大风和暴雨的频次多、强度大,灾害损失大。
As an important area and strategic tocus of population concentration,national economy and society development, coastal zone could be stricken fiercely and fatally by losses caused by typhoon disasters. Study on losses assessment of typhoon disasters in coastal area is thus proved to be quite urgent. Based on date concerning typhoon disasters during 1990 to 2007, representationa~ indexes are selected to attempt establish a loss assessment model and typhoon disaster losses and their relationships with disaster-causing factors in coastal areas are analyzed and evaluated. Results show that the losses present a descending trend in most of the coastal areas, each with different extents. The descending extent is lower than 10% in Zhejiang, Jiangsu and Hainan provinces. The average losses among 18 years are relatively higher in Zhejiang, Fujiang and Guangdong provinces. The frequency, intensity of wind and rain and the losses of typhoon disaster are heavier in the southern areas of Shanghai.
