银川灌区水资源利用优化模式初探

Preliminary Investigation on Optimization Models of Water Resources Utiliza tion in Yinchuan Irrigation Region

本文分析了银川灌区水资源利用的现状和存在问题。建立了2000年该灌区灌溉用水的线性规划模型,运用计算机运算求出了灌区2000年农业用水结构,并确定了地下水的开发利用量和引黄规模。

This paper analyzes the existing state and some problems of water resources utilizations in yinchran Irrigation Region, A linear programming models is set up for irrigation water of this Region in 2000. At last, the structure of water for agriculture is deduced by operation of EC and the quantity of utilizing ground—water and water diverted from yellow river is defined.
