Abstract: Based on the location observation data of Chinese ecosystem research network about four typical zonal vegetations, this paper analyzed the difference of hydrological functions in different climatic zones. The results showed that the soil bulk density increased with soil depth, but soil porosity, soil effective moisture, saturation moisture content and water content per month are opposite. The runoff of Dinghu Mountain was the highest among the four forests and consumed the largest portion of precipitation. The evapotranspiration of Ailao Mountain was the highest and consumed the largest portion of precipitation; the soil water absorption capacity of Ailao Mountain was the largest and followed by Dinghu Mountains,Changbai Mountains and Xishuangbanna, while the soil water storage ability of Dinghu Mountain was the highest, and followed by Changbai Mountains,Ailao Mountains and Xishuangbanna.

Key words: zonal vegetation, soil, hydrological function
