摘  要:
介绍了作物水分生产函数的国内外研究现状及目前常用的数学模型,并对其特点和适用性进行了探讨,运用系统工程中动态规划的方法对灌溉规划进行优化求解,使其在我国干旱、半干旱地区,尤其是西北干旱区节水灌溉模型中起到指导作用。根据其参数的地域性特点,提出了在西北地区、尤其新疆绿洲农业区建立主要作物水分生产函数的紧迫性。

摘  要:
This paper introduces the studies of crop-water production function and the present mathematical model and discusses their suitability.Besides,the paper uses the method of dynamic planning to optimize the water-saving irrigation model and makes it play a guiding role on irrigation in aridity,semi-arid region,especially the Northwestern arid district of our country.According to the regional characteristic of its parameter,we have put forward the urgency of setting up the main crop-water production function in the Northwest,especially the oasas of Xinjiang.
