摘要
试验结果表明：刺槐、柠条、沙棘林土壤入渗性能均高于荒地。从初渗率到稳渗率，刺槐林最高，初渗率柠条林最高，沙棘林稳渗率高于柠条林。３种林地的土壤抗冲性均大于荒地。土壤表层抗冲性以柠条林最大，刺槐、沙棘林次之，荒地最小。刺槐、柠条、沙棘林土壤冲刷模数与土层深度、冲刷坡度、须根含量关系密切，并呈多因子乘积函数关系。为研究乔灌林保持水土机理和土壤抗冲性测定提供依据。
The results showed that capacities of soil infiltration in Robinia pseudoacacia,Caraganamicrophylla and Hippophae rhamnoides woodlands were higher than that in wasteland.The infil-tration rate from initial to final in Robinia pseudoacacia wooland was the highest and the initial in-filtration rate in Caragana microphylla woo and was the highest.The final infiltration rate in Hip-pophae rhamnoides woodland was higher than in Caragana micropylh woodland.Soils of threewoodlands had higher infiltration than that of wasteland. Surface soil anti-scourability of Caraganamicrophylla was the highest among four kinds of land use, and the lowest one was wasteland.Thesoil wash modulus of three kinds of woodlands had closely relation with soil layer deepth, washslope, root conten.The relation between soil wash modulus and soil layer deepth,wash slope,root content was a function of multiple factors product.The study would present foundation ofmechanism for soil and water conservation of shurb and hight forest,meanwhile it would presentbasis of measurment for soil anti-scourability.
