This paper summarizes the results on high temperature and heatwave researches in eight aspects, including damage types,standard, climatic characteristics, causes of formation, response to globalwarming, monitoring and warning technology, disastermitigation strategies and techniques. Although heatwave and high temperature is a relatively short time weather disaster, it can result in evere damages to agriculture, and its basic weather characteristic is high temperature and low humidity. It occurred in many parts of hina from June toAugust. Atmospheric circulation anomaly is the directcause for its formation, and climatewarming and drying is the mportant reason for its frequentoccurrence. A deep understanding on characteristics ofhigh temperature and heatwave damage is important, and itwill provide some guidance for  isastersmonitoring and predicting and secure agriculture production.

 Based on the climatic; data of  ten years(1991一2000)China are analyzed.  The result show that the hail distribution is the spatial一temporal distribution(harac;teristi<、of hail in Northwest in belt patterns and the main hail zone is in the middle part of Tibetan plateau Qilian mountain and the west part of Tianshan mountain the more frequent、entre is in the south side along the east一WPSt mountains than that and the east side along the north一、outh mountains } the date o<(urrin} hails in mOthe south part of the plateau and the hail duration is lone but the hail days are the north part of Tibetan Plateau is earlier fewer than that in the south part of the plateau from the (urves of dec;adal and pentad evolution of hail days
