中国的酸雨模拟及控制对策研究

STUDY ON THE MODELING OF ACID RAIN AND THE CONTROL COUNTER-MEASURES IN CHINA

本文从大气污染源、大气污染特征、降水化学特征和酸雨污染特征等方面论述了我国大气污染和酸雨污染属于“煤烟型”,并将我国的大气环境状况与世界其它一些国家作了比较分析。进一步利用我们发展的南京大学酸沉降模式系统 ( NJUADMS)模拟了中国地区的 SO2 地面浓度和硫沉降分布 ,并与实际观测资料和亚洲酸雨模式 ( RAINS- ASL A)的计算结果作了比较。最后从能源结构和经济发展状况出发 ,论述了我国控制 SO2 污染和酸雨的目标、政策。

The characteristics of air pollutant sources,air pollution,precipitation chemistry and acid rain pollution in China are discussed,the conclusion of which is that air pollution and acid rain in the country are the pollution of coal fired type.The situations of atmospheric environment in China and in some other countries are compared..Further,the distributions of ground level concentration of SO 2 and S deposition are simulated by Nanjing University Acid Deposition Model System,and results of the simulation and that of RAINS-ASIA are compared.Finally,starting from the structure of energy sources and economic development conditions in China,the aims,policies,regulations and measures to control the pollution of SO 2 and acid rain are discussed.
