针对PM2．5的武汉市大气监测点位的布局研究

武汉城市规模的扩大以及市内和周边的产业布局调整使得原有的大气监测网络不能准确反映城市大气污染现状，亟需进行布局优化。研究基于宏观视角，通过对武汉市自然条件、污染源分布和城市的发展规划进行综合分析，认为武汉市的大气污染以本地区的污染源影响为主；由于城市发展的“主城为核，多轴多心”空间结构，每个新城建成区应增设2-4个空气质量评价点，并按照人口比例作为权重纳入空气数据均值的计算；位于主城区的原有监测点基于PM2.5与原有监测项目有比较显著的相关性，可以继续使用。

Layout Optimization for PM2.5 Monitoring Sites in Wuhan

Due to the expansion of Wuhan and the adjustment of the city and the surrounding industrial layout, the original air monitoring network can not accurately reflect the current state of the urban air pollution. Based on the macro view, a comprehen sive analysis was made on the natural conditions, pollution source distribution and Wuhan city planning. It is concluded that the pollution sources in the region are the main influence factors for air pollution of Wuhan. Because of the muhieore spatial structure of urban areas,2 to 4 air quality evaluation sites should be added in each new urban district, and the proportion of the population in every district should be as a weight for monitoring data in the calculation of average air data. Because PM2.5 has significant cor relation with the original monitoring project, the original monitoring sites located in main urban area should remain in force.
