New Model of Green Environment System of Driving Out Dust Pollution with Collecting Rain Water for Beijing City

For solving the problems of dust pollution and water resource scarcity, the paper suggested the model and method of green environment system of collecting rain water and cleaning out dust for Beijing according to the principle of urban ecology. This is a effective way to construct a urban ecosystem which will be health orderly, steady sustainable , strong self cleaning, and to produce great ecological and economic benefit; For example, the important water resources for developing urban forestry is great much saved.
