摘  要：
研究3～4年生柠条、沙柳、沙地柏和白沙蒿的单根(根径为0.3～3mm)在两个生长时期内瞬时大风作用下的抗拉力和平均抗拉强度。结果表明,在生长季初期(5月初)和旺盛生长期(8月中旬),4种植物根系的单根抗拉力与直径均呈幂函数正相关关系;抗拉力和平均抗拉强度均表现为柠条>沙柳>沙地柏>白沙蒿;沙柳、沙地柏、白沙蒿在生长季初期的抗拉力和平均抗拉强度大于旺盛生长期,柠条反之。

摘  要：
Anti-tension and tensile strength of single root(the diameter range of roots is between 0.3 and 3 mm)under momentary gale were determined.Plants studied were Caragana microphylla Lam,Salix psammophila C.Wang et Ch.Y.Yang,Sabina vulgaris Ant.,and Artemisia sphaerocephala Krasch.,which were 3～4 years old.The function of momentary gale was simulated by instantaneous tension.Results show that in the early growth period(early May)and the vigorous growth period(mid-August),anti-tension of four kinds of single root shows a positive exponential relation to diameter.The plants,in terms of anti-tension and average tensile strength,are ranged in the order of Caragana microphylla Lam>Salix psammophila C.Wang et Ch.Y.Yang>Sabina vulgaris Ant.>Artemisia sphaerocephala Krasch.Anti-tension and average tensile strength of single root in the early growth period is greater than that in the vigorous growth period except Caragana microphylay Lam.
