摘　　要：通过对兰州市自然环境条件的介绍,分析了兰州市大气污染主要是由于燃煤造成的。天然气作为一种清洁能源,能够减少燃煤造成的大气污染。通过燃气替代燃煤,可以减少污染物的排放,改善兰州市空气质量状况。运用环境经济政策的理论,分析了"煤改气"的可行性。Having introduced the natural conditions of Lanzhou City, we can analyse the main cause of the air pollution what is brought about by the burning coal. As a source of cleaner energy, the natural gas is able to reduce the air pollution by burning coal. The transformation of coal - fired boiler reduce the pollutant emissions, and cut down the atmospheric pollution, improve the condition of the air quality in Lanzhou City. In this paper, with the use of environmental and economical policies, I analyse the feasibility to the proposal of the “coal to gas”.
