摘      要：[Objective] The research aimed to study the distribution characteristics of high temperature damage and its influence on the rice yield in the area along Huaihe River.[Method] The meteorological data of 10 stations in the area along Huaihe River during 1965-2009 and the yield data of Anhui single-season middle rice during 1967-2006 were *** occurrence characteristic of summer high temperature weather and the intensity of high temperature damage in the area along Huaihe River were *** on the previous high temperature damage index of rice,Changfeng County where was the typical rice planting zone in the area along Huaihe River was as the representation,and the yield damage loss rate risk of high temperature damage in Changfeng was analyzed by combining with the historical yield data.[Result] The high temperature weather in the area along Huaihe River frequently *** high temperature damage presented N shape trend from west to *** occurrence frequency of high temperature weather in Huainan and Bengbu where were in the middle area along Huaihe River was more and was less in Huoqiu and Shouxian where were near the south mountain area of *** occurrence time mainly focused from the middle and last dekads of July to the first dekad of August after the plum *** this time,it was the booting,heading and flowering periods of single-season middle rice,and the influence on the rice yield was *** damage loss rate of single-season middle rice yield in Changfeng County along Huaihe River continued to increase as the increasing of high temperature damage *** the occurrence probability *** intensity grade of high temperature damage disaster loss rate which happened frequently concentrated mainly in levels I and *** longer the high temperature damage duration in the reproductive growth stage of rice was,the bigger the damage loss rate *** the corresponding occurrence probability was small,and vice versa.[Conc
