摘　　要：根据 1 951～ 2 0 0 0年江西省降雨量、降雨日数、降雨变率等资料 ,统计和分析江西省夏季干旱期间降雨量、降雨日数、降雨变率等变化与地理分布客观特征。文章还对江西干旱标准、干旱指数与伏、秋干旱时空分布客观特征等进行分析。分析结果为江西人工增雨抗旱作业提供依据。According to the all province precipitation data of 1951 to 2000, the objective characteristics of variation and geographical distribution of the rainfall amount, the number of rainy days, and precipitation variability during summer drought in Jiangxi Province are calculated and analyzed. Meanwhile, the drought criterions, drought indexes as well as spatial and temporal distribution characteristics within dry periods are analyzed. The results can be used as the bases of artificial precipitation enhancement operation in Jiangxi Province.
