| Abstract: | The line intercept method been applied to sampling for field data.V/m ratio t-test,negative binomial parameter,index of clumping and index of patchiness have been used to analysis the distribution pattern and female-male proportion of Sabina vulgaris community Population on the Mu us sandland.The result indicated that female-male proportion is 0.6:1,spatial distribution pattern for contagious distribution. |
| Keywords: | Mu Us Sandland Sabina vulgaris Female-male Proportion Spatial Distribution |
