| 摘 要： | 目的]为了寻求不同应用条件下适宜的PAM分子量。方法]通过模拟降雨试验,研究在不同雨强、坡度情况下,施用高分子量PAM(PAM(H))和中分子量PAM(PAM(M))对土壤侵蚀的影响。结果]施用PAM(M)使得侵蚀产沙量增大,PAM(H)和PAM(H)+PAM(M)能够有效地防止土壤侵蚀。结论]在特定的自然条件下,可以选择适宜的PAM分子量类型。

| Abstract: | Objective]The research aimed to explorer the appropriate molecular weight of PAM under the different application condition.Method] The effect of treating loess soil with dry PAM,and either moderate PAM or high PAM was studied using rainfall simulation applied at different intensities to soil inclined at different slope angles.Result] Erosion increased when the loess was treated with PAM(M),but decreased significantly when treated with PAM(H) or with PAM(H) and PAM(M).Conclusion] The appropriate molecular weight of PAM could be selected under the specific natural condition. |
