Abstract: The paper studied the niche features of dominant species in the communities of Paeonia suffruticosa var.spontanea using methads of Levins,Shaanon-Wiener coefficient of niche breadth and Petraitis coefficient of niche overlap,in the area of Majiagou,Jishan,Shanxi province;Shuiyukou,Yongji,Shanxi province;Wanhuashan,Yanan,Shaanxi province,Erxianqiao,Huayin,Shaanxi province.It is concluded that the niche breadth of Paeonia suffruticosa var.spontanea and other dominant species vary with the change of ecological factors,such as water conditions in soil,temperature,elevation and light.Water condition is the main ecological factor which affects the niche breadth.Paeonia suffruticosa var.spontanea and other 13 dominant species appear a certain niche overlap in the six communities.

Key words: urban green space, shrub, biomass model.
