摘要
探讨了３０年生油松天然林的水文效应。林冠截留量占大气降雨量２０．０２％，林内降雨量占７７．１５％，树干径流量占１．８０％；凋落物层的饱和持水量４．４７ｍｍ，有效持水量２．６１ｍｍ；年地表径流量６．６４１～１０．９９１ｍｍ，径流率１．２２％～１．４１％。
The hydrologic effects of 30-year old natural Chinese pine forests have been measured. It is concluded that the interception of forest canopy accounted for 20.02% of the rainfall,precipitation inside the stand took 77.15% througfall and stem flow 1.80%;the saturated water retaining capacity of forest litters was 4.47mm,effective water storing capacity 2.61mm,surface run-off 6.641～10.991mm,and run-off co-efficient 1.22%～1.41%
