本文采用大系统递阶结构,用频率组合和固定用水两种方法进行了现状年(1985年)及近期(2000年)关中西部四大灌区用水联网调度的可行性分析。四大灌区规模大,结构复杂,是蓄、引相结合的灌溉系统。分析结果认为:实行联网调度可以解决羊毛湾、宝鸡峡两大灌区的缺水问题;石头河水库水源充沛,是解决宝鸡峡灌区缺水的重要水源;羊毛湾灌区可从冯家山水库获得一定的水量,同时,改善了宝鸡市用水紧张的状况。据估算,全系统年调节水量2000～20000万m~3。可增产粮食0.55亿kg,获益3850万元,同时,可向宝鸡市第二热电厂年供水量4000万m~3,效益可观。
In this paper, a large-scale hierarchical structure was used to analyze the feasibility of water network deployment in the four major irrigation districts in the western part of Guanzhong with the current year (1985) and the recent (2000) by means of frequency combination and fixed water. The four major irrigated areas are large-scale and complex in structure, and they are integrated and integrated irrigation systems. The analysis shows that the implementation of networked dispatching can solve the problem of water shortage in two major irrigated areas of Bay of wool and Baojixia. The abundant water source in Shitouhe reservoir is an important source of water to solve the irrigation in Baojixia Irrigation District. Water, at the same time, improve the water shortage in Baoji City. It is estimated that the annual system-wide regulation of water 2000 ~ 20000 m ~ 3. It can increase grain output by 0.55 billion kg and benefit 38.5 million yuan. At the same time, the annual supply of water to the second thermal power plant in Baoji City can reach 40 million m ~ 3, with considerable benefits.
