以覆盖度为20%左右的乔木固沙林为研究对象,通过野外观测两种水平配置格局林内地表粗糙度和摩阻速度。结果表明:行带式配置林内地表摩擦阻力较随机配置的高,其对土壤风蚀的抑制作用也较显著。
With the coverage of about 20% of the arbor sand fixation forest as the research object, through the field observation of two levels to configure the layout of the forest surface roughness and friction velocity. The results show that the surface frictional resistance of the belt-in-track configuration is higher than that of the random configuration, and the inhibition effect on soil wind erosion is also significant.
