Abstract: CALPUFF model and photochemical grid model were adopted to predict the air environment around Yanshan industrial garden by setting up two scenarios of recent and long-term planning. The results showed that the air quality in the area could meet the national second standard under the scenarios of improving the present farms and strictly controlling the pollution discharge within the permitted total amount of the new farms. Furthermore, the air quality of the TinghuLake area could meet the national first standard.
