摘要
为了定量分析能源政策和城市用地布局对大气环境质量的影响,给城市总体规划提供决策支持,以南宁市为例,应用ISC 3模型和情景分析相结合的方法对SO2控制策略进行模拟研究。结果表明,若不采取任何控制措施,到2010年,研究区域的SO2年日平均浓度将达58μg/m3,超标率(浓度年均值超过国家二级标准的区域面积占总面积的比例)为38.94%;单一的控制措施可以减轻污染水平,但不能完全满足国家二级标准要求;若采取综合控制策略,平均浓度达到34μg/m3,所有网格均满足国家二级标准要求。上述探讨,为制定南宁市大气污染控制对策及调整空间用地布局提供了有效的支持。
The influence of energy policy and spatial layout on the air quality was evaluated using Nanning, Guangxi as an example to develop policy making strategies for integrated urban planning. The ISC3 model and the scenario analysis approach were used to simulate sulfur dioxide control strategies in Nanning. The results show that the average SO2 concentration in the region will be 58μ/m^3 in 2010 without any control strategies and that a single control strategy will reduce the pollution but not meet the National Secondary Standard. However, the average SO2 concentration can be controlled to 34μg/m^3 with an integrated control strategy, which will meet the National Standards.
