Abstract：Based on the investigation of 13 plots of the Loess area in Shanxi Province,The changes of the surface random roughness with stand density and growth season were studied by the needle roughness instrument.The results show that the surface random roughness is significantly and positively correlated to stand density,y=0.001 5x+0.314 9,R2=0.935 3.Every plot is different from surface random roughness.On the same area,surface random roughness of barren grass slope>shrubbery's.And The surface random roughness varied with growth season,August>April>October,and appear inverted "V" form.The change extent of surface random roughness under natural forest is smaller than the artificial forest.
