摘　　要：沿海围垦区盐渍化程度高,淡水资源不足,阻碍围垦区经济发展。为保障围垦区水资源供给,进行盐碱环境下多水源联合调配研究。以江苏沿海滩涂开发为背景,在分析当地水源特征的基础上,结合研究区需水要求,提出雨水和微咸水等非常规水资源与传统水资源联合利用模式,将平原区河网概化为虚拟的河网水库,对多水源多用户供水关系进行分解,建立盐碱环境下多水源联合调配模拟模型,得到围垦区不同水平年不同保证率下的供水量及其组成。研究表明,充分利用雨水和微咸水等非常规水资源,可缓解沿海围垦区水资源紧张局势。in coastal reclamation area, high degree of salinity and the shortage of fresh water resources become critical constraints for local economic development of Jiangsu Province. Multi-water resources allocation in saline-alkaline environment is researched for improving local water use efficiency. Based on water resources features and water demands, the conjunctive utilization mode of unconventional water and conventional water is presented, including rainwater and brackish water. The river network of plain areas is generalized as a virtual reservoir and the water supply systems of multi-water and multi-user are decomposed into three simple systems, then the simulation model of multi-water conjunctive allocation is developed to calculate water supply volume and its compositions of coastal reclamation area under different scenarios. The results demonstrate that the water scarcity of coastal reclamation area can be relieved to some degree by fully using unconventional water resources, such as rainwater and brackish water.
