| 摘 要： | 依据生物气候相互补偿原理,用作物彼此间产量相对比来确定沈阳市、辽中和新民县粮豆作物播种面积的合理结构,以此达到在不利的天气条件下,保持多年平均总产水平,并使总产均方差最小的稳产目的.用二次规划法解出最优化方案。

| Abstract: | in accordance with the principle of complementary relations existingbetween living rganisms and climate,by comparing the yields betweencrops,efforts were made to decide the rational structure of sowing areasof grain and legume crops in Shenyang,Liao Zhong and Xin Min,in orderto maintain a desirable combined average yield lovel over years under adverseweather conditions,and achieve a stable yield by keeping a mimmum meansquare deviation.The optimimzed scheme was derived through quadraticprogramming |

| Keywords: | stable crop yield bioclimate sowing area optimized model quadratic function |
