摘　　要：该文是对福建省古田水库地区12年(1975—1986年)人工降雨随机试验效果进行综合评价。统计分析表明244次随机试验得出20%(α<0.05)左右增雨效果。各种观测分析(冰核、雨水中 Ag^+ 含量,雷达回波、雨滴谱)及数值模拟结果为人工增雨统计结论提供了初步的物理学解释。Artificial experiments were performed in the Gutian reservior region during April toJune of 1975-1986.The statistical analyses from 244 experiments indicate that the effectof precipitation enhancement can reach about 20% by seeding.Meanwhile,the variouscloud physics observations,including the concentration of ice nuclei,the Ag^+ content inrain water,the features of radar echoes and the raindrop size distribution,and numeri-cal simulations have been conducted.The results provide a preliminary physical expla-nation for the statistical conclusions.
