| 摘 要： | 径流小区对比试验表明：栎林采伐后，林冠层截留功能丧失，灌草层、枯落物层截留有所增大；地表径流系数增大７９％，产流起始时间提早；壤中流分层流量不同，径流系数增大；大暴雨时雨水入渗速率减小。由地表径流水流失的养分总量占雨水输入林地的养分总量，栎林地为４３．１４％，栎林采伐迹地为４１．９５％。

| Abstract: | Compared with those in oak stand,the interception of the brushand litter layer in cutting blank increased to varying degrees as well as thecoefficients of surface runoff and subsurface runoff.There appeared anearlier occurance of surface runoff and a lower infiltration rate in period ofstorms. The surface runoff carried away 43.14%of nutrients inputted byrainfall in oak stand and 41.95%in cutting blank. |
