摘要
运用径流小区法研究了闽北封山育林地的水土保持效应,结果表明:封山育林的保水保土效应显著,封山育林地的年径流量为18.90 mm,是裸露地年径流量的1/30;年土壤流失量为27.61(kg.hm-2)是裸露地土壤流失量的1/1 900.说明封山育林措施能起到良好的水土保持效果,尤其是在降雨多发的夏季及春季,能起到良好的调蓄降水,降低降雨对土壤的侵蚀作用.
The effect of forest conservation on soil and water conservation in northern Fujian Province is studied with the method of runoff plot in the paper. The results indicate that the effect of forest conservation on soil and water conservation is of great significance. The annual runoff of the forest conservation is 18.90 mm,which is 1/30 of that of the bare land. The annual soil loss of the forest conservation is 27.61 （ kg.hm^-2 ） ,which is 1/1 900 of that of the bare land. It suggests that the forest conservation measures have a good effect on soil and water conservaticn, especially during spring and summer. It plays a good role in regulating the rainfall and reducing the soil erosion brought by the rainfall.
