利用黄河水资源模拟模型，进行了一系列算例计算．以基本算倒为基础，对影响黄河水资便分配的有关政策作了个别调整，包括供水优先序的改变、新的引水工程投入、农业灌溉面积的发展、水库供水范围的调整和某灌区用水效率提高等．通过计算结果对比．将各项用水政策的改变对区域或部门水资源利用及效益的影响作了敏感性分析评价。 Using a simulation model of the Yellow River water resources, a series of example calculations were made. Based on the basic calculation, we made some adjustments to the relevant policies that affect the allocation of water resources in the Yellow River, including the priority changes in water supply, the investment in new water diversion projects, the development of agricultural irrigation areas, the adjustment of reservoir water supply scope and the use of water Improve efficiency and so on. By comparing the calculation results. The impact of changes in water policies on the utilization and efficiency of water resources in regional or sectoral regions was analyzed and evaluated.
