摘　　要： 利用清代档案和其他文献资料，重建了1711～1911年间昆明雨季降水的分级序列。在重建中采取了纠偏措施，有效地解决了资料存在的系统偏差问题。对重建序列的分析表明，昆明降水存在较大的波动，可以分为4个大的时段。总的来说，18世纪的雨季降水略少于19世纪。和喜马拉雅山区达索普冰芯恢复的印度季风降水序列的比较表明，19世纪70年代是两个序列中降水量最多的10年，且19世纪后半期同是两个序列波动较大的时期。但也有不一致的地方，说明两地降水机制有所差别。同时太阳活动的世纪周期对昆明的雨季降水有影响。对中间分辨率资料的开拓利用，有助于拓展高分辨率历史气候序列重建的范围。 There were almost 4000 items about precipitation, disasters and harvest of Kunruing in the archives of the Qing period. Using these materials and other historical documents, based on analysis of periodical characteristics of modern precipitation, the series of precipitation grades in Kunming during 1711-1911 is reconstructed. System deviations are modified successfully by means of the rectification measures. Comparison of the dryness/ wetness grade with precipitation grade indicates that the series of precipitation grades can express precipitation of the rainy season more actually. The analysis indicates that the 201 years from 1711 to 1911 can be divided into four phases according to the precipitation of the rainy season in Kunming, and the amount of precipitation during the 18th century is slightly lower than that during the 19th century . This indicates that the amount of the 1870s is the maximum through comparison with the series of Indian monsoon precipitation based on the Himalayas Dasuopu ice core, and the amount of the second half of the 19th century fluctuates more obviously in both series. However, the amount of precipitation during the last 30 years of the 18th century is higher in Kunming, but is lower during the 18th century, all indicated by the precipitation series of Dasuopu ice core. The Characteristic of monsoon precipitation in the Yunnan Plateau is unique. Two peaks of 90a macula cycle correspond with the two peaks of the series of precipitation grades in Kunming, the 90a solar activity cycle affects the precipitation of rainy season in Kunming possibly. It is help ful to extend the area of reconstructing the highresolution series of historical climate by exploiting and utilizing medium resolution materials.
