| 摘 要： | 以陕南秦巴山区典型小流域坡面为例，研究了分布在不同坡住的5种不同土地利用方式下的土壤剖面特征、物理性质和养分分异特征，结果表明，土层厚度及其受坡度的影响与地表植被高度呈负相关；土壤全氮含量与地表植被高度也呈负相关，与坡度成正相关；土壤有机质含量与地表植被高度呈正相关。

| Abstract: | This paper selects typical small watershed slope as research material in Qinba mountain areas of southern Shaanxi Province,studies the soil profile characteristics,physical properties,and nutrient distribution.The results show that,the soil layer thickness and the effect from slope degree increases as the height of ground vegetation;the total N and P represented as an increasing trend as the ground vegetation height increases,but a decreasing trend as the slope degree increases.As for the soil organic matte... |
