| Abstract: | The over grazing is an important reason that causes the succession of vegetations, so it is significant of study the law of grazing succession for making reasonable grazing systems and im- proving the salinization grassland. Six cluster analysis methods have been used to divide the graz- ing successional seres of Aneurolepidium chinense grassland into light grazing, proper grazing, heavy grazing, over grazing and extreme grazing five stages in the Shong-Nen plain. |
