摘　　要：根据高空环流形势和地面降水资料,对2002年9月27日秦皇岛市石河水库上游实施的人工增雨作业进行了分析和检验。增雨作业影响区5个雨量点平均雨量108.4 mm,其中最大达160.2 mm(非影响区雨量33 mm)。此次增雨作业使石河水库洪水总量达803×104m3,为水库增加260×104元经济效益。对作业后1 h作业影响区和非影响区雨量进行秩和检验,结果表明作业影响区和非影响降水差异明显,人工增雨效果显著。文中对火箭人工增雨作业方法和时机进行了探讨。The analysis and evaluation are made of a small-scale rocket rain enhancement operation conducted over the Shihe Reservoir of Qinhuangdao on 27 September 2002.The average rainfall of the five rainfall stations within the operating area is 108.4 mm,with the maximum up to 160.2 mm(33 mm over the non-operating area).The rain enhancement operation increased the total water storage of the reservoir up to 803×10~4 m^3.The evaluation is conducted on the rainfall amounts one hour after the operation over the operat...
