摘  要：
对东北黑土区不同植被配置下的土壤抗冲性及其影响因素进行研究,为水土保持植物选择和配置提供一定理论依据。采用野外采样与原状土冲刷试验相结合的方法。结果表明:坡位对土壤抗冲性具有一定影响,胡枝子与紫穗槐在不同坡位上的土壤抗冲性不同,且在土层上层(0～10 cm)存在差异,下层(10～20 cm)的变化规律相近;不同植被配置的土壤抗冲性随冲刷时间延长而不断增强;影响因素与土壤抗冲性的相关性排序为:砂粒含量>土壤含水量>WSA_(0.25 mm)>根表面积密度>土壤容重>土壤有机质。胡枝子+杨树的模式最优,说明胡枝子更适合在杨树林下生长,可作为水土保持的优良树种用于杨树林的植被配置。

摘  要：
The research on soil anti-scourability and its influencing factors under different vegetation configuration in the black soil region of northeast China will provide a certain theoretical basis for the selection and allocation of plants for soil and water conservation. Field sampling and runoff scouring experiment were carried out. The results showed that the slope position had a certain influence on the soil anti-scourability. The soil anti-scourability of different slope positions for Lespedeza and Amorpha was different, and the change rule was different in the upper layer(0-10 cm) of the soil, and was similar in the lower layer(10-20 cm). The soil anti-scourability of different vegetation configurations gradually increased with the scouring time. The relationship between the influencing factors and the soil anti-scourability was ranked according to the correlation: sand content > soil water content > WSA_(0.25 mm)> root surface area density > soil bulk density >organic matter. The model of Lespedeza + poplar was the best, indicating that Lespedeza was more suitable for growing under poplar trees, and could be used as an excellent tree species for soil and water conservation in the vegetation configuration of poplar forests.
