文中对人工油松林地土壤理化性质、林冠截留,枯落物持水、土壤入渗、地表径流、土壤侵蚀等几方面比较系统地进行了研究。结果表明,油松林具有显著的水土保持功能;水土保持功能受林龄和林分结构的影响,林龄越大,水土保持功能越显著;混交林的水土保持功能高于纯林。同时对与水土保持功能密切相关的生物量进行了计算,建立了总生物量和各器官生物量的回归方程。
In this paper, the physical and chemical properties of artificial Pinus tabulaeformis woodland, canopy interception, litter water holding, soil infiltration, surface runoff and soil erosion were systematically studied. The results showed that the Pinus tabulaeformis forest had significant water and soil conservation functions. The function of soil and water conservation was affected by forest age and stand structure. The greater the forest age, the more significant the soil and water conservation functions were. The function of soil and water conservation of the mixed forest was higher than that of the pure forest. At the same time, the biomass that is closely related to soil and water conservation function was calculated and the regression equation of total biomass and biomass of each organ was established.
