Influence of Railway Construction on the Local Thermal Environment in Beijing City

In order to know the influence of railway construction on the local thermal environment, we select the Beijing Railway Station, the Beijing West Railway Station, the Beijing North Railway Station and the Beijing South Railway Station as experimental subjects. Based on the observation data, the distribution of every station environment temperature field is analyzed in detail. The influence of environmental factors is approached. So it draws the following conclusions:There are the mini heat islands on the railway stations. The greenbelt and the waters in the urban area can weaken the local temperature. The single environmental factor has a great effect on the local thermal environment.
