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 ％ 。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.
