  生态位相似比例
     In this paper the niche of 11 main species of plants in Balong region of the Chaidamu Basin was analyzed by a quantitative method. The niche breath,niche proportional similarity and niche overlap of 11 main plant species were measured,and their biologic significance was discussed,aiming to provide a theoretical reference for the restoration of vegetation in this region.
