摘　　要：铁路的发展将促进站点周边城区人口密度、城市交通量等因素的变化,人口密度和城市交通量的增加将造成大气污染等环境质量的改变,形成对站点周边城区的次生环境影响.以大气质量为例,通过对北京市大中小不同规模的车站周边区域的大气质量的测试,分析了北京市铁路站点周边区域的总悬浮颗粒物TSP、SO2、NOx等大气污染物,同时,调查了铁路站点周边区域的城市交通量和人口密度,通过最小二乘法的统计分析,研究了人口密度、城市交通量等与主要大气污染物含量的相关性,探讨铁路次生环境影响的控制因素.Railway development will cause the change around railway station. Increase of population density of population density and traffic flux in the area and traffic flux will exacerbate atmosphere poilution. This kind change will produce deduced atmosphere environment impact. In this paper, through detecting atmosphere quality in the area around railway station, some principal atmosphere polluting substance of T SP（total suspended particles） 、 SO2 、 NOx in the area around railway station are analyzed. At the same time, population density and traffic flux in the same area are investigated by the actual statistic method. Through applying least square method, relativity of the population density and traffic flux with atmosphere polluting in the area around railway station is studied. Deduced atmosphere environment impact in the area around Beijing railway station caused by railway development is also explored.
