摘要
为了提高金沟河流域枯水期水资源的利用效率,以流域灌溉效益最大为目标,建立需水量~灌溉效益数学模型,根据动态规划的原理和特点,利用软件Visial Basic编制计算程序对模型进行求解,使得灌溉效益模型计算较为简单,计算结果准确。通过计算与现状相比,金沟河流域3个灌区枯水期水资源得到了合理配置和利用,流域缺水量减少,灌溉总效益比以前显著增加。
In order to improve the water resources using efficiency in low flow period of Jingou River Basin,the water demand-irrigation benefit model with target of the maximum basin irrigation benefit is set up in this paper.According to the principles and characteristics of dynamic programming,the VB software is used to draw up programs and solve the model.The irrigation benefit model is simple and the result is exact.Through comparing the calculation result with the situation,the water resources in low flow period of three irrigation district of Jingou River Basin is allocated and utilized reasonably by using this model.The shortage of water decreases while the irrigation efficiency increases significantly.
