| 摘 要： | 对侧柏人工林分的林冠降雨截留及地表径流进行观测，要冠降雨截留量与降雨量相关，截留量随降雨量的增加而增加，截留率则相反，年截留率３３％；地表径流量和土壤侵蚀量与降雨量正相关，年地表径流量和土壤侵蚀量分别为３９．５ｍｍ和１３２７ｋｇ／ｍｈ＾２。

| Abstract: | The crown interception and overland flow in arborvitae plantation had been observed.The results indicted that crown interception in the stand(crown density 0.9) was closely related to the precipitation.Crown interception increased and interception percentage decreased with the increase of precipitation and annual interception percentage was 33%.The amount of overland flow and soil erosion were closely correlated with the precipitation.Annual overland flow and soil erosion are 39.5mm and 1327kg/hm 2. |
