随着四化的进展,水资源对经济建设的制约作用越来越突出。除了合理开发利用地上、地下水以外,开发和利用空中水资源已经成为现实性的研究课题。人类现在还不可能“呼风唤雨”。但是国内外的科研实践证明,在一定范围内人工调节“小气候”(包括人工降雨)已经不再是幻想。由于这一课题带有战略性质,且非短期可以见效,所以需要早作安排。英国早已把水资源的流域管理和改造气候联为一体,在调剂雨量的实验方面,业已取得成果。美国于七十年代中期制订了八十到九十年代的具体科研攻关目标(从提高融雪灌溉能力,到增加高原干旱区降雨量,以至减
With the progress of the four modernizations, the restriction of water resources on economic construction has become increasingly prominent. In addition to rational development and utilization of ground and groundwater, the development and utilization of air water resources has become a real research topic. It is impossible for mankind to “do anything” now. However, scientific research at home and abroad proves that artificial regulation of “microclimate” (including artificial precipitation) within a certain range is no longer an illusion. Since the topic is strategic in nature and can not be effective in the short term, it needs to be arranged early. The United Kingdom has long combined the watershed management and climate change with water resources and has already achieved results in the experiment of adjusting rainfall. In the mid-1970s, the United States set the goal of specific research projects in the 1980s and 1990s (from improving snowmelt irrigation capacity to increasing the rainfall in plateau arid areas,
