Abstract:

As pollution reduction efforts promoting and deepening in China, how to allocate the pollutant reduction amount fairly and reasonably among different regions is an important issue worthy of highly concern.A reasonable and equitable allocation criterion system was put forward based on the comparison with the current pollutant (reduction)allocation methods and the allocation thoughts,and on the full consideration to the influence factors about pollutant from production,reduction to emission process.Taking COD reduction allocation as a case study,a specific index system was established.Focusing on the differences in economic structure,pollution control engineering and environment quality,using entropy weighting method,an improved proportional distribution method was raised,based on the reduction allocation of COD between provinces.The results show that the improved proportional distribution method,taking into account the differences between provinces and cities,can be taken as an appropriate method for various types of pollution reduction allocation among different districts in China
