Abstract:

This study focused on the quota allocating of initial discharge permits problem on lake basin industry point source.This paper set "Fairness, Efficient and Feasible" as the allocation princess,through the lexicographic minimax model with weight coefficient of the objects’ initial discharge permits shortage,and proposed the lake initial discharge permits lexicographic quota allocation model and the algorithm.Taken initial NH3N discharge permits allocation of 27 kinds main industry in Taihu Lake Basin of Jiangsu Province,from both the industry’s initial discharge permits shortage rate and industry pollution control benefits,an empirical study is given for comparative analysis of the effects of three kinds quota allocations computed by the equal shortage rate quota model,the equal environment capacity proportion quota model,the lexicographic quota model.The result showed that:relative to the other two kinds of quota model,the quota allocation scheme computed by the lexicographic quota model achieved the lowest average industry shortage rate as 4613%,and the best average industry pollution control benefits.And the analysis indicated that based on the "Fairness,Efficient and Feasible" allocation principles,the lexicographic quota allocation method could be more effective in promoting industry pollution control technology upgrade and regional industrial structure upgrade
