摘要: 针对现有关联分析只从平面的角度来确定因素之间的关联程度的方法,本文通过空间距离公式把最优和最劣关联度结合起来,得到一个综合关联度,使分析问题的角度从平面拓展到空间,并结合小麦产区成本收益的实际情况进行评价研究,为小麦的收益评价提供了一种新的思路。

Abstract: From grey relational analysis, this paper used a space distance formula that put together the best relational degree with the worst relational degree. From that, a comprehensive degree can be got. And through researching cost-benefit of wheat-producing areas , a new way of thinking has been provided.
