    摘要:

    针对乌伦古河流域水资源短缺、灌溉挤占生态用水等问题,以生活、工业、灌溉、河道生态基流、河谷林草及补湖生态用水为调度目标,设置开源、节流方案集,建立了以生态缺水量和社会经济缺水量最小为目标的水库群生态调度模型,采用人机对话模拟优化算法求解模型。结果表明:各节流方案的河谷林草和补湖供水保证率能够满足设计要求,缓解了灌溉用水与生态用水间的矛盾,但2017现状水平年和2025远景水平年需水方案的灌溉保证率未满足设计要求;当开源+节流方案调水量超过1.0亿m3时,满足农业灌溉、河谷林草和补湖的供水保证率要求,消除了灌溉用水与生态用水间的矛盾;随着调水量超过1.0亿m3且持续增加,对河谷林草、补湖缺水量、破坏深度等影响不大,推荐1.0亿m3为最佳调水量。

    Abstract:

    To solve the problems of water resources shortage and ecological water occupation by irrigation in the Ulungur River Basin, using the domestic water, industrial water, irrigation water, river ecological base flow, and ecological water of river valley grassland and lake replenishment as the operation objectives, an operation scheme set to increase water sources and reduce water consumption was set up. An ecological optimal operation model of the reservoir group was established to minimize the ecological and socio-economic water shortage, and the man-machine dialogue simulation optimization algorithm was used to solve the model. The results show that the guarantee rates of water supply for river valley grassland and lake replenishment and in each water consumption reduction scheme can meet the design requirements and alleviate the contradiction between irrigation water and ecological water. The irrigation guarantee rates of the water demand schemes in 2017 and 2025 do not meet the design requirements. When the transferred water volume in the combined scheme of increasing water sources and reducing water consumption is more than 100 million m3, the water supply guarantee rate requirements of agricultural irrigation, river valley grassland and lake replenishment are met, and the contradiction between irrigation water and ecological water is eliminated. With the increase of the water diversion volume of more than 100 million m3, it has little effect on the water shortage and damage depth of river valley grassland and lake replenishment. It is recommended that 100 million m3 is the best water diversion volume.
