| 摘 要： | 影响黑杨派南方型无性系生长的综合土壤-立地因子有:有效水分、物理性状、通气条件和土壤养分.综合土壤-立地因子由反映立地质量的土壤-立地子因子构成.通径分析表明:影响土壤有效水分的土壤-立地子因子主要是局域位置、地形条件和地下水位;影响物理性状的是质地与结构;影响通气条件的是经营水平;而影响土壤养分的土壤-立地子因子是速效钾和pH值.

| Abstract: | Soil available moisture, physical condition, areation and nutrient availability are four synthetic soil-site factors which effect the growth of Southern Type Clones of Aigeiros Section. Every synthetic soil-site factors is composited by several minor factors which effect the site quality directly. By path analysis, the position ( outside or inside dams ) , groundwater level and drainage are the important factors for available moisture; soil structure and texture for physical condition, the level of management is for areation; and the exchangeable K and pH for nutrient availability. |
