摘　　要：The total 15 severe droughts are discovered with the aid of the 'RetrievalSystem of Chinese Historical Climate Records' for the last 1000 years. The droughts are extensive toenvelope more than 4 provinces and persistent to cover 3 yr or more, and their severity isequivalent to or in excess of that in the 1930s in China. According to the documentary records andrestorations it can be inferred that most droughts are more severe than those in the last 50 years.The 15 droughts may either occur warm or in a cold climate background, with 11 of the 15 cases inthe cold phase. This indicates the difference in climate correspondence between China and northernAmerica, showing the severity of the events in China to be in a cold instead of a warm climatesituation. That is likely to relate to the monsoon climate in eastern Asia.The total 15 severe droughts are discovered with the aid of the 'RetrievalSystem of Chinese Historical Climate Records' for the last 1000 years.
