二氧化硫排放总量控制指标新分配方案探讨

Generally the TSP and SO2 are pollutants of major concern in environmental policy making in china. The issues about the share sum of SO2 emission in different provinces and cities are studied in this paper, and the results show that the share qualities do not comply with the air quality capacity of their provinces and cities, and the distribution to regions sum of SO2 emission does not meet the requirement of state’s development strategy either. A new distribution scheme has been put forward in this paper in which the land area of provinces and cities is used as the index of air quality capacity and population as the index of true need of economic development and the society. The share of SO2 emission sum in cities is corrected by weight coefficient in mathematic model in order to express the greater need of economic development level and the high population density in city areas. The results from modeling computation indicate notable differences from the current distribution arrangement in the country. The areas polluted by serious acid rain are just where the current figures exceed greatly the model’s results, while the areas where air quality can meet the requirement of the state’s second class standard level comply with the model’s result. The new share scheme of SO2 emission in the paper is more reasonable and equitable for society and different regions.
