摘要
本文应用灰色系统理论对江苏沿海旱粮棉区的几种新型种植制度的经济、生态效益作了综合评估。结果表明:依据各种植制度的灰色关联度排序所进行的综合评估与其实际表现是一致的,而且能更好地反映各种植系统内部的关联性和提高评估的科学性。
Mathematical method of the relational grade analysis of the grey system theory and its application in assessing economic and ecologic effect of cropping system was described with a set of data from some rational cropping system in coastal cotton area of Jiangsu. The results demonstrate that this new method is simpler and more convenient than any other oncs and that they were similar to actual expression of cropping system.
