6、 here is the main method was introduced. Industrial reasonable layout and just facilitating the spread of pollutants and factory using waste gas, each other between reduce exhaust emissions. The area with high efficiency, the central heating boiler instead of the dispersed of low chimney, with high

7、efficiency of the boiler instead of the dispersed of low emissions chimney way. This is the city of the prevention and control of atmospheric pollution powerful measures.,The forest is the main body of the terrestrial ecological system, has the wind the solid earth, water conservation, the absorptio
