中文摘要	以兰州市榆中县夏官营古城的苔藓坡面为研究对象,通过野外调查,研究苔藓的生长环境特征.选择有代表性的自然坡面进行风蚀、雨蚀实验,研究苔藓坡面的抗风蚀、雨蚀能力.取当地的原状土样进行室内土工实验研究其强度特征.结果表明:苔藓能显著提高黄土坡面的抗风蚀、雨蚀能力和抗剪强度.苔藓覆盖度越大,抗风蚀、雨蚀能力越强.相比较无苔藓的坡面,苔藓覆盖度达到40%时,抗风蚀能力可提高2~3倍,抗雨蚀能力可提高3~4倍,苔藓覆盖度超过40%后,抗风蚀、雨蚀能力提高幅度会下降.随着苔藓覆盖度增大,原状土样的内聚力显著增大,抗剪强度整体增大.
英文摘要	The moss slope of Xiaguanying ancient castle in Yuzhong County,Lanzhou, was chosen as the research object. Some field investigations into the growth environment characteristics of the moss slope were conducted. In order to study the capability whereby mossy slope resists wind erosion and rain erosion, a representative natural slope was selected to conduct wind and rain erosion tests. Original state soil samples for local indoor soil test were taken to study the strength characteristics. The results showed that moss could significantly improve the anti-wind and anti-rain erosion capacity and also the shear strength of the moss slope. The higher coverage area of moss on the slope, the stronger the ability to resist wind and rain erosion. Compared with slopes without moss,the anti-wind erosion capacity of the slope with a coverage of 40% increased 2-3 times, and its resistance to rain erosion also increased 34 times. But if the coverage area were beyond 40%,these raised indexes would decrease. With increasing of the mosscovering area, the cohesion of undisturbed soil increased significantly,and the shear strength increased on the whole.
