Abstract:By investigating autumn continuous raining disaster in past years in three provinces of Central China and using newly-revised discrimination standard and degree evaluation criteria in climate disaster monitor and analysis system of Wuhan Regional Climate Center,the paper analyses the temporal and spatial feature of autumn continuous raining.Meantime,in terms of disaster losses of autumn continuous raining in representative region,the high influence years and high risk areas are investigated from the angle of disaster risk and some corresponding measures such as risk avoidance and risk shifting et al are proposed for high risk areas.The results show that:during the recent fifty years,the autumn continuous raining in three provinces of Central China decreases significantly at 0.21 time per decade averagely,and the more decreasing trend is caused with closing to the southern.The autumn continuous raining in every area shows consistent decreasing trend,and it will decrease more quickly in the west than in the east of the area,especially the decreasing trend of the part area in the west of Hubei and Hunan reaches significant level.The decreasing trend of autumn continuous raining in heavier level becomes more obvious.The risk analysis method is better applied to the evaluation of high influence years and high risk areas of autumn continuous raining disaster in three provinces of Central China,and the high influence years matches well with actual disaster.The high risk area of autumn continuous raining includes the southwest part of Henan(such as Luanchuan,Xixia),the west of Hubei(such as Fangxian,the west of Yichang,the Enshi area),and the west most part and southeast part of Hunan(such as Chenzhou).Some corresponding measures such as risk avoidance and risk shifting et al are proposed for high risk areas.
