摘  要:
该文以藁城县为对象,根据小麦各生育期对水的需要,通过对气象因子变化的数字模拟,得到了较准确的小麦灌溉定额和轮灌周期.把机井布局和井、泵、机配套作为一个整体,使用含有参数的非线性规划方法,以灌溉费用最小为目标,求出了最优的机井布局和井、泵、机配套方案.为保证农业持续稳定生产,根据地下水可开采量,采用线性规划方法,得到了灌溉效益最大时的作物布局方案.

OPTIMIZATION OF THE MOTOR-PUMPED WELL DISTRIBUTION IN THE WELL IRRIGATION FIELDS IN GAO CHENG COUNTY
摘  要:
In this paper according to the water demands of wheat in different growing period, the irrigation quota and the irrigation cycle of wheat in Gao Cheng County are exactly derived from digital simulation Of the variation of the meteorological factors. Taking the minimum irrigation cost as the objective function and taking the distribution of motor-pumped wells and the complete sets of wells, pumps and motors as a whole system, we evaluate the optimum pattern by means of non-linear programme method with variable coefficients. In order to ensure continuous and stable crop yields, based on the amount of usable ground water, we obtain the acreages of crop distribution with maximum irrigation benefit by linear programme method.
