摘要
采用线性规划方法，利用计算机，以水和投资限额为限制因素，从２３个方案中选出了效益较高的方案，总投资４０万元，年供水量４５．３６ｍ３，栽苹果树９６．０９ｈｍ２，梨２０ｈｍ２，山楂２７ｈｍ２，杏１７ｈｍ２，石榴７ｈｍ２，枣２．７２，柿１６．７ｈｍ２，小麦１１４．３ｈｍ２，花生５．７ｈｍ２，棉花６ｈｍ２，年总产值可达３００万元以上。
Using linear programming and taking water and investment limit as the limitingfactors, the best scheme was selected from the 23 ones with the help of computors. For thebest scheme, total itvestment was 400,000 yuan, annal irrigation 45.36 m3, and the cultivationareas for apple 96.90 hm2, pear 20 hm2, hawthorn 27 hm2,apricot 17 hm2,pomegranate 7 hm2 , date 2.7 hm2 , persimmon 16.7 hm2 , wheat 114.3 hm2, peanut 5.7hm2,and cotton 6 hm2. Annual output value could be more than 3,000,000 yuan.
