摘 要 ：对杉木林生态系统净化水质功能研究结果表明,随着大气降水而进入杉木林生态系统的物质中,有二氯丁烷、苯等有机污染物,还有Ph、Ca等重金属元素。经过林冠层、地被物和土壤层的截留作用,这些污染物质不仅种类减少,而且浓度大为降低。进一步阐述了森林净化水质的机理和效益。为森林净化水质的功能,提供了依据。

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 Ph, 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.
