摘　　要：研究旨在定量化评估江苏省空中云水资源可开发量及基本特征。根据云水收支方程,将参与大气云水循环且未降落到地面的资源定义为空中云水资源。利用1981—2010年EAR-Interim高分辨率再分析资料的风场及云含水量,计算江苏上空云水资源年均总量、时空特征及变化趋势。结果表明,资源年均总量353.1亿t,春夏季偏多,秋冬季偏少,开发潜力巨大。旱期(缺水期)沿淮淮北最多,达70.8亿t,沿海垦区、苏南环太湖次之;非旱期总量约占全年58.3%。近30年,云水资源呈下降趋势,平均每10年减少18亿t。建议加大开发力度,实现常态化开发利用,率先建立淮北、沿海、环太湖开发利用重点作业区,加强开发利用技术研究,提高开发效率。The paper aims to quantitatively evaluate the amount and characteristics of cloud water resources of Jiangsu Province. According to the function of inflow and outflow of cloud water, the cloud water resources were defined as the resources which participated in the recycle of atmospheric cloud water, but did not fall in ground. The fields of wind and cloud water content from the high resolution reanalysis data（ERA-Interim）during 1981- 2010 were applied to calculating the total annual amount of cloud water resources of JiangsuProvince in average, whose spatial-temporal characteristics and variation trend were analyzed. Results showedthat： the annual average amount reached 35.31 billion tons. It was more in spring and summer, but less inautumn and winter. In drought（water shortage） period, the amount reached the maximum of 7.08 billion tonswithin the areas in Huaibei along the Huai River, followed by that in the coastal reclamation region and areasaround Taihu Lake, respectively. The amount during non- drought period accounted for 58.3% of the totalannual amount. The cloud water resources of Jiangsu had a decline of 1.8 billion tons per decade within thepast 30 years. It is suggested to increase the exploitation intensity and realize the normalization of exploitationof the resources. The major operation areas should be established in Huaibei, the coastal region and around Taihu Lake. In order to improve the efficiency of exploitation, the technology should be advanced.
