东陵区是沈阳市郊区。过去,由于农作物生产结构不合理,致使农产品的商品率和经济效益都比较低,1983年以来,进行了资源调查和农业区划。1986年又在调查和区划所收集的资料和数据基础上,应用线性规划建立数学模型,调整作物结构,形成了新的作物生产规划。按照新的规划全区种植业净产值可达11309.9万元,比1983～1985年三年平均净产值增加2004.9万元,粮豆总产可达4.3亿斤,蔬菜总产量可达6.3亿斤以上,保证了满足供应城市和自给生产的需要。
Dongling District is the suburbs of Shenyang. In the past, due to the irrational structure of crop production, commodity prices and economic benefits of agricultural products were relatively low. Since 1983, resource surveys and agricultural zoning have been conducted. On the basis of the data and data collected in the survey and zoning in 1986, a mathematical model was established by using linear programming to adjust the crop structure and form a new crop production plan. According to the new plan, the net output value of the planting industry in the whole region will reach 113.09 million yuan, an increase of 20.499 million yuan over the three-year average net output value of 1983-1985. The total output of grain beans will reach 430 million kg and the total vegetable output will reach over 630 million kg, To meet the needs of supplying cities and self-sufficient production.
