两次半偏减法集对势方法评价水资源承载力

Subtraction set pair potential method for evaluating water resources carrying capacity based on double semi-partial connection number

为更好体现水资源承载力变化趋势及其所处等级,应用偏联系数和减法集对势原理,从事物的普遍联系角度出发,对五元联系数中的差异项进行两次半偏处理。构建了两次半偏减法集对势方法,该方法减小了五元减法集对势中差异项的剩余量并避免了在计算中存在人为设定系数0.5的情况。该方法在淮北平原的应用表明:2015—2019年,淮北平原6个地市的水资源承载力大多为3~4级,仅2018年宿州、蚌埠和淮南市水资源承载力为2~3级,且2015—2019年淮北平原6个地市的水资源承载未出现偏同势、同势,这说明淮北平原整体水资源承载能力较弱。两次半偏减法集对势法拓宽了水资源承载力的分析评价思路。

In order to better reflect the trend of water resources carrying capacity and its grade,this paper applies the principle of partial relation number and subtraction set to deal with the difference items in the five-element relation number twice from the general relation point of view.The method of double partial subtraction set pair potential is constructed,which reduces the remaining amount of difference term in five-element subtraction set pair potential and avoids the artificially set coefficient 0.5 in calculation.The application of this method in Huaibei Plain shows that:from 2015 to 2019,most of the water resources carrying capacities of the six cities in the Huaibei Plain were between levels 3 and 4,and only those of Suzhou,Bengbu and Huainan cities in 2018 were between level 2 and level 3,and the water resources carrying capacity of the six cities in the Huaibei Plain did not show partial homogeneity or homogeneity during 2015-2019,indicating that the overall water resources carrying capacity of the Huaibei Plain was weak.The method of double semi-partial subtraction set pair potential broadens the thinking of analyzing and evaluating the carrying capacity of water resources.
