摘　　要：以重庆主城九区314个挡墙样方为研究对象,调研挡墙上植物的组成及分布格局特征.结果表明,挡墙上木本植物以桑科为主,构树和黄葛树是挡墙上优势乔木树种;挡墙上木本植物种群中乡土植物占比77.2%;挡墙固有属性值中高度、分阶、倾斜度及缝隙大小分类等级与挡墙上木本植物的物种多样性指数呈正比关系,且同属性等级划分上公园及森林用地周边挡墙比居住及建设用地周边挡墙木本植物物种多样性高.The composition and distribution pattern characteristics of the plants on the retaining walls were investigated in 314 retaining wall plots in the 9 th District of Chongqing.The results showed that the woody plants on the retaining walls were mainly distributed by the family of Moraceae.Broussonetia papyrifera and Ficus virens were the dominant tree species on the retaining walls.Native woody plants accounted for 77.2%of the trees on the retaining wall.In the intrinsic attribute value of the retaining wall,the hierarchical gradient of height and the classification grade of gap size were positively correlated to the species diversity index of woody plants on the retaining wall,and the species diversity of woody plants on the retaining wall around the park and forest land was higher than that around the residential and construction land in the same attribute classification.
