摘　　要：为进一步挖掘联系数所隐含的各类信息价值以更准确地分析区域水资源承载力发展趋势,利用同一度a与差异度b、对立度c与差异度b之间增量的变化信息,同时将(a-b)当作(b-c)的正向驱动系数、将(c-b)当作(b-a)的负向驱动系数,在此基础上将所得减法邻正联系数加上减法邻负联系数构建减法全邻联系数。将该方法与现有的两种邻联系数方法用于不同地区公共场所卫生监督质量、某医院多年间医疗质量的发展趋势分析比较,同时在区域水资源承载力评价中进行实证应用。结果表明:减法全邻联系数在差异度接近于零的情况也适用,所得结果较其他两种邻联系数方法更接近实际,有助于邻联系数方法的推广应用,对联系数伴随函数的深入研究具有重要意义。用减法全邻联系数计算安徽省水资源承载力3个代表性指标的减法全邻联系数增量曲线与级别特征值增量曲线基本呈对称状态,减法全邻联系数增量的正负可直接用于判断水资源承载力评价指标的发展趋势,为集对事件的发展趋势分析提供了新途径。In order to further excavate the various information values implied in the connection number,the development trend of regional water resources carrying capacity can be more accurately analyzed.This article regard(a-b)as the forward driving coefficient of(b-c),(c-b)as the negative driving coefficient of(b-a),based on the information between the identical degree a and the discrepancy degree b the contrary degree c and the discrepancy degree b.By defining the concept of subtractive positive connection number and subtractive neighbor negative connection number,the expression of subtractive full neighbor connection number is obtained.The subtractive full neighbor connection number and the existing two neighbor connection number methods are compared and analyzed in the trend analysis of health supervision quality in public places and medical quality in a hospital in different years.The results show that the subtraction improves the special case in which the discrepancy degree is close to 0,which is helpful to the perfection of neighbor connection number method and its popularization and application.At the same time,the subtractive full neighbor connection number is applied to the evaluation of water resources carrying capacity in Anhui Province.The results show that the increment curve of three representative indexes and the increment curve of the rank eigenvalue are basically in the state of axial symmetry of the transverse coordinate.The values and increments between the subtractive full neighbor connection number and the level eigenvalue of all indicators are closely negative correlated.Therefore,it can be seen that the positive or negative increment of the subtractive full neighbor connection number can directly judge the development trend of the evaluation index of regional water resources carrying capacity.It provides a new approach for the analysis of the trend of development of set pair events.
