应用系统分析的原理和方法 ,从经济的角度探讨了南方圩区麦田塑料暗管排水埋深和间距的优化 ,建立了以单位面积工程费用最小为目标函数的塑料暗管间距和埋深的数学模型 ,不同生态类型圩区的计算结果表明符合田间实际情况。
The principles and methods of system analysis were used to optimize the depth and spacing of plastic tube drainage in southern polder areas from the economic point of view. The mathematics of plastic tube spacing and depth was established with the objective of minimizing the construction cost per unit area The results of the models and polder areas of different ecotypes show that they are in line with the actual situation in the field.
