Abstract:According to the comparison research of 3 watershed of tropical mountain rain forest in Jianfenling,nature recovery raniforest ecosystem with 40 years could store 51.8% of rainfall from May to September, and could recruit runoff of 143.5 mm from October to February. At the same time,the response of runoff ranged from 32.7% to 62.5% on heavy rainstorm.Concentration of COD,NH + 4 N,phenol,Zn,Cu,Pb,Cd,Ni in precipitation and runoff were lower than the first standard of area water environment in virgin and n...
