| 摘 要： | 根据不设调压管的微灌田间管网的特点，引入０－１变量，建立了微灌田间管网优化设计的混合整数规划模型。采用这一模型，可在满足允许水头差要求条件下，合理地选择毛管和支管的规格，使其造价之和最低。这一方法便于计算机求解，适合解决各种地形条件下的微灌田间管网优化设计问题。

| Abstract: | According to the characteristics of the field network for drip irrigation,mixed integer pro gramming model is established to optimize field network of drip irrigation by introducing 0-1 variable. The optimal solution of mixed integer programming is found through combining enumeration method with simplex method.The dimensions of laterals are determined by enumeration method and the dimensions of submain pipes are determined by simplex method to minimize the investment of field network.In all kinds of topography,the procedure can be used to slove optimization problems of the field network,in which the length of lateral is shorter.The procedure is easy to calculate in computer with less internal storage and higher operational speed. |
