利用上海台风研究所及国家气象中心整编的中国台风灾情资料,分析了中国致灾台风造成的人员伤亡、房屋倒损、农田受淹及直接经济损失等灾情特征.引入了定基物价指数,改进了台风灾害指数(ATDI指数)的计算方法,基于1980-2004年间所有致灾台风的灾害指数的聚类分析,将致灾台风的灾害分为:轻灾(或小灾)、中灾、大灾(或中偏重灾)和重灾4个等级,并据此对1980-2004年间中国致灾台风的灾情进行了客观评估.结果表明:平均每年约有7.2个台风对中国造成明显灾情,最多的年份多达11个、最少年份也有4个.中国致灾台风的频数逐年减少,但造成的灾情却逐年趋重,因台风而伤亡的总人数逐年上升(死亡人数下降)、倒损房屋和受淹的农田面积以及造成的直接经济损失均逐年递增,倒损房屋、受淹的农田面积、直接经济损失的年平均增长率分别为1.33×10~4间/年、2.28×10~4 hm~2/年和14.56亿元/年.1980-2004年间,单个致灾台风而言,倒损房屋、受淹的农田面积、直接经济损失的平均增长率分别为581.4间/个、880.0 hm~2/个和0.33亿元/个.从台风灾害指数看,1990年代中期,中国的台风灾害较为严重,其中1996年最重,而1998年则是1980-2004年间台风灾害最轻的年份.
利用上海檯風研究所及國傢氣象中心整編的中國檯風災情資料,分析瞭中國緻災檯風造成的人員傷亡、房屋倒損、農田受淹及直接經濟損失等災情特徵.引入瞭定基物價指數,改進瞭檯風災害指數(ATDI指數)的計算方法,基于1980-2004年間所有緻災檯風的災害指數的聚類分析,將緻災檯風的災害分為:輕災(或小災)、中災、大災(或中偏重災)和重災4箇等級,併據此對1980-2004年間中國緻災檯風的災情進行瞭客觀評估.結果錶明:平均每年約有7.2箇檯風對中國造成明顯災情,最多的年份多達11箇、最少年份也有4箇.中國緻災檯風的頻數逐年減少,但造成的災情卻逐年趨重,因檯風而傷亡的總人數逐年上升(死亡人數下降)、倒損房屋和受淹的農田麵積以及造成的直接經濟損失均逐年遞增,倒損房屋、受淹的農田麵積、直接經濟損失的年平均增長率分彆為1.33×10~4間/年、2.28×10~4 hm~2/年和14.56億元/年.1980-2004年間,單箇緻災檯風而言,倒損房屋、受淹的農田麵積、直接經濟損失的平均增長率分彆為581.4間/箇、880.0 hm~2/箇和0.33億元/箇.從檯風災害指數看,1990年代中期,中國的檯風災害較為嚴重,其中1996年最重,而1998年則是1980-2004年間檯風災害最輕的年份.

The characters of casualty, damaged or collapsed house, inundated farmland area, and direct economic loss caused by tropi-cal cyclones (TC) in China during 1980- 2004 are analyzed based on the typhoon disaster loss data compiled by Shanghai Typhoon Institute and National Meteorological Center. Considering direct economic loss and the influence of society development, an Advanced Typhoon Disaster Index (ATDI) for objective assessment of disaster degrees is developed. Based on the ATDIs of all tropical cy-clones, the disasters are divided into four categories: gentle, moderate, heavy, and severe. It is found that on average 7.2 TCs caused remarkable damages in China each year. The annual damage increases with increasing casualty (the death toll dropped dramati-cally), damaged or collapsed house, inundated farmland, and direct economic loss, although the number of TCs causing disasters has dropped in China during 1980 - 2004. The average yearly growth rates of the damaged or collapsed house, inundated farmland, and direct economic loss are 1.33 × 10~3 rooms, 2.28 × 10~4 hm~2, and 1.46 billion RMB, respectively. As far as single TC is concerned, those average growth rates are 581.4 rooms per TC, 880.0 hm~2 per TC and 33 million RMB per TC, respectively. Based on the AT-DI, the damage caused by TCs more severe in the mid 1990's with the severest (gentlest) damage occurring in 1996 (1998) from 1980 to 2004.
