摘要
从土壤物理性质、土壤蓄水量、土壤入渗、地表径流和土壤侵蚀方面研究了北京山区密云水库上游油松等林分调节水分的效应。研究表明,油松等林分具有明显的改善土壤物理性质、增加林地蓄水量和入渗量、减少地表产流的作用,根据坡面和流域对比试验的观测资料可知,所研究的林分具有明显的调洪作用和减少土壤侵蚀等效益.
The water regulat ion effect of Pinus tabulaefimis Carr. and other forest stands isstudlto on soil physical properties,water storage capacity of soil,soil permeability,overland flowand soil erosion. It is confirmed that those forest sta nds have dist inct effect of improving soilphysical properties,increasing soil permeability and water storage capacity of soil ,and decreasingoverland flow. According to data observed from constrast experiments of plots and watersheds,the forest stands have distinct function of regulating flood and effect of decreasing soil erosion.
