| 摘 要： | 针对集对分析中差异不确定系数i的取值不确定问题，分别将差异度与同一度和对立度的关联度作为i的取值，运用灰色理论巾的绝对关联度计算方法对i进行求解，并应用到富锦市土壤质量评价中，结果符合实际情况。研究结果表明，采用灰色绝对关联度计算差异系数是可行的，为集对分析中差异系数i的求解提供了新的思路和方法。

| Abstract: | Due to the uncertain value problem of variation coefficient i in set pair analysis, this paper used the correlation degree of variation degree and identical degree and opposite degree as the i value, respec- tively, to calculate i by using absolute correlation degree calculation method of grey theory, and obtained the satisfactory results of soil quality evaluation in Fujin. The results showed that it was feasible to calculatebased on absolute correlation degree of the grey theory, and provided a new idea and method for solving variation coefficient i in set pair analysis. |
