【摘要】 根据自治区九·五计划要求,在棉、粮协调和保持棉区持续发展的原则上,用线性规划方法对新疆2000 年种植业结构进行了规划,结果表明:即在其他作物稳定在1995 年的播种情况下,到2000 年需在棉产区累计开荒净增耕地35-33 ×104hm2 ,使总耕地达到348-16 ×104hm 2 ,作物播种面积达到342-94 ×104hm2 ;其中粮食作物160 ×104hm2 ;棉花面积105-2 ×104hm 2 ;甜菜13-32 ×104hm 2 。开荒主要集中在南疆,占72-8 % 。

【Abstract】 A rational planting plan for the new task was put forward accordng to the principle of coordinated development of cotton and grain production and meeting the requirements of the 9th-Five -Year Plan of Xinjiang.Planting scheme in 2000 obtained by linear program shows that it is necessary to increase 35.33×10 4 hm 2 of net cultivated land by reclaiming wasteland in the end of 2000.Then the total cultivated land will reach 348.16×10 4hm 2 and the planting area will reach 342.94×10 4hm 2,with which 160×10 4hm 2 for grain,105.2×10 4hm 2 for cotton,and 13.32×10 4hm 2 for beet.
