By comparing the differences of plant diversity between artificial measures ( enclosed land for reforestation, thinning and renewal) and contrast area ( natural way) , the effects of different measures for soil and water conservation ecological rehabilitation in vegetation rehabilitation are analyzed.It is showed that the diversity by artificial measures is higher than natural diversity.Variance analysis and multiple comparisons show that for shrubs, the effect between artificial measures and natural ways has significant difference.The diversity index for artificial measures is higher than that for natural ways, but the measures of enclosed land for reforestation, thinning and renewal have no significant difference; and for herbs, the effect between artificial measures and the natural way has no significant difference.The change in evenness is almost consistent with that in the diversity index and ecological dominance is almost opposite.In short, soil and water conservation ecological rehabilitation may increase plant diversity.
