基于环境基尼系数的控制单元水污染负荷分配优化研究
Application of total water pollutant load distribution in control-unit based on the environmental Gini coefficient
摘要
Abstract
Gini coefficient,the concept of welfare economics,was introduced into the process of water pollutants load distribution in the Songhua River Basin.Synthetically considering the socio-economic-resource-environmental factors of water cycle,and from the perspective of difference in social and economic development,scientific and technological progress level,water pollution control level and resource endowment,this paper took COD and NH3-N load as control factor,and then selected index system consisting of per capita GDP,industrial output value of key industries,the per capita water pollutants strength,industrial wastewater pollutant removal efficiency,urban wastewater removal rate,the water resource quantity in unit area and the percentage of monitoring section which was worse than V grade and used contribution coefficient as a parameter that characterized external unfairness in building up a water waste load distribution model based on Gini coefficient and further made a water waste load distribution scheme in the 33 control-units of Songhua River basin based on the equity principle.The optimized model aiming at minimal sum value of each Gini coefficient was built by setting reasonable constraint conditions and computing optimized value of Gini coefficient and the amount of pollutant reduction in the 33 control-units was calculated finally.According to the research,the Gini coefficients based on the 7-index in the year of 2012 exceeded 0.4,which was the level of international red warning line.This result showed that the distributions of COD and NH3-N emissions were extremely uneven especially in the Songhua River mainstream and the Second Songhua River basin.In the optimized allocation of COD reduction program by the Lingo model in every river basin unit in 2020,the control-unit 21 had the largest reducing quantity of COD with the number of 18.2 thousand tons per year.And the largest decrease rate was control-unit 10 with the number of 8％,while the corresponding two values in the reduction plan of NH3-N were 800 tons per year and 8％ in the contr 21.关键词
