摘 要:黄藏寺水库是黑河干流控制性骨干调蓄工程,水库为多目标开发,供水对象涉及下游额济纳绿洲天然生态、国防科研、中游灌区灌溉及工业、生活、发电用水等,加之黑河中游具有地表水地下水多次转换、重复利用的特点,边界条件复杂,限制因素多,给水库调节库容论证带来了较大困难。按照“合理调配中下游生态和经济社会用水,提高黑河水资源综合管理能力,兼顾发电等综合利用”的水库开发任务,基于水库供水范围内黑河中下游地区不同需水特点和要求,根据水库运用方式,利用黑河二元结构水资源配置模型,进行了多方案、长系列径流调节计算。综合分析推荐黄藏寺水库调节库容采用2.95亿m3,能够满足实现黑河分水方案和供水、灌溉、发电的需要,助力黑河水资源综合管理提档升级。

Abstract: Huangzangsi reservoir is a key control regulation and storage project in the main stream of Heihe River. The reservoir is developed with multi-objectives and the water supply objects refer to the natural ecology, national defense scientific research of Ejina Oasis in the lower reaches, irrigation, industrial, domestic and power generation use in the middle reaches of Ejina Oasis. In addition, the middle reaches of Heihe River has the characteristics of repeated conversion and reuse of surface water and groundwater, complex boundary conditions and many limiting factors, which brings great difficulties to the demonstration of reservoir regulation capacity. According to the reservoir development task of “rational allocation of ecological, economic and social water use in the middle and lower reaches of the Heihe River, improving the comprehensive management capacity of water resources of the river, taking into account the comprehensive utilization of power generation and other comprehensive utilization”, based on the different water demand characteristics and requirements of the middle and lower reaches of the Heihe River within the reservoir water supply range, according to the reservoir operation mode, using the Heihe dual structure water resources allocation model, a multi-scheme and long series runoff regulation calculation was carried. According to the comprehensive analysis, it is recommended that the regulating capacity of Huangzangsi Reservoir should be 295 million m3, which can meet the needs of water diversion scheme, water supply, irrigation and power generation of Heihe River and help to upgrade the integrated management of water resources of Heihe River.
