摘 要:为了有效开发空中云水资源,增加地面降水量,笔者利用1981—2010年辽宁省阜新市国家基本气象观测站历史天气资料和降水实况数据,依据人工增雨技术原理,统计、分析了阜新地区云水资源分布特征和人工增雨潜力,并对人工增雨对策进行研究。结果表明:(1)阜新地区年均拥有云水资源总量238.4×108m3,而实际年均降水量只有471.8 mm,相当于水资源量47.2×108m3,仅为所拥有云水资源总量的16.5%,可见阜新地区具有较大的人工增雨潜力;(2)利用本研究建立的适合阜新地区人工增雨的天气模型和技术指标,开展具有针对性的12次人工增雨作业试验,增雨效率平均为18.3%,比原来提高了5.2%,年均可增加水资源量约2.5×108m3,对阜新地区科学、有效实施人工增雨作业,最大限度地开发云水资源,增加全市水资源总量,缓解干旱,具有较大的指导意义。For exploring cloud water resources and increasing the total precipitation effectively, according to the principles of artificial precipitation enhancement, and based on the historical weather and live precipitation data from Fuxin National Basic Meteorological Stations between 1981 and 2010, the research was conducted to analyze the cloud water resource distribution characteristics and the countermeasures and potentiality of artificial precipitation enhancement in Fuxin City of Liaoning Province. The experiment results showed that: (1) Fuxin Region had an average annual total cloud water resources of 238.4× 10^8 m^3, while the actual average annual rainfall was only 471.8 mm, that was equivalent to 47.2×10^8 m^3 water resources, only 16.5% of total cloud water resources, therefore, Fuxin Region had great artificial precipitation potentiality; (2) the author carried out 12 times of artificial precipitation enhancement operation experiment by using the weather model and technical indexes above that were suitable for Fuxin Region, the artificial precipitation efficiency was 17.8% on average, 5.2% higher than before, and the average annual precipitation could be increased 2.5x l0s m^3 approximately. All of these had a great significance for guiding Fuxin Region to carry out artificial precipitation operation, maximize the development of air cloud water resources, increase the total precipitation and mitigate drought both scientifically and effectively.
