摘要
该文以系统工程的原理方法,结合山东省陈垓引黄灌区北二干渠系统实际情况,分别以灌溉净效益最大和轮灌时间最短为目标,建立了作物最优种植面积和渠系优化配水模型,应用计算机求解,取得了满意的作物优化布局和优化配水成果。实践证明,本项成果在节水、灌溉增产、提高灌区科学管理水平等方面都有着十分重要的作用。
This paper developed an optimal crop planting pattern and water allocation of canal system based on the sys- tem engineering principle and method. The objectives are the maximum irrigation net benefit and minmum rotation time. A case of study has been eompleted according to the practical situation of the north second main canal. The results of the optimal crop pattern and water allocation are satisfied. The practice has proved that the model has great significance in water saving, crop yield increasing and enhancing scientific management level of irrigation area.
