【Abstract】 This paper studied the spatial pattern of 1 hm 2 sample fenced from 1989 on the Songnen plain in north east China,where is a region with extremely heterogenous vegetation because of alkalization.Patch dynamics of different species was different and the role of the species varied with restoration succession stages.The results gave strong support to patchiness persistence hypothesis.更多还原
