Abstract:

In this paper the function of Chinese fir plantation ecosystem in cleaning pollutants was studied. The results show many kinds of organic pollutants such as 2.3-dichloro-butane, benzene, and heavy matal elements Pb, Cd from atomsphere enter the ecosystem through rainfall. As a result of these pollutants intercepted by canopy, grund cover, forest soil while travelling in the hydrologic process, the species and the concentration of these pollutants are greatly reduced in output water. The mechanism and benefits of forest purifying water were discussed in the paper.

Key words: Chinese fir plantation, Water quality, Pollutant, Purification
