摘要
通过对闽西红壤小流域综合治理开发中，不同品种、不同密度立体经营模式的油桐林造林前后的土壤理化性质及根量的研究，结果表明：油桐林土壤疏松多孔，通气透水性好，土壤水分状况得到改善，土壤有机质含量增加，营养元素积累和养分供应能力得到提高，初步证明该造林模式具有一定减少水土流失，改良土壤理化性质的功能。
By means of a preliminary study on soil physical and chemical properties as well as root mass before and after planting of the different variety and different density plantation of Aleurites of space model of management, during the comprehensive harnessing and development of red soil small watersheds in West Fujian The results exhibit that the soil of the plantation of Aleurites is loose and porous,soil water and air character improves,soil organic materials content increases,the ability of soil nutrient accumulation and supplying strength To a certain degree ,this model has the function of improving soil and reducing the soil and water loss
