摘    要:为大连以及气候类型相近城市的绿地规划和植物多样性建设提供科学依据.本研究对105个不同类型和不同规模的大连城市绿地样方内植物群落的树种组成、群落特征和物种多样性进行分析,结果表明:调查样方共有植物种类262种,其中乔木类115种,灌木类50种,草本类97种.乔木与灌木树种的比例约为1.0∶0.43;常绿植物与落叶植物的种类比例约为1.0∶4.3.在五种绿地类型中,总体物种多样性表现为公共设施绿地、居住绿地和公园绿地较高,道路绿地次之,其他绿地最差.

关 键 词:大连市  城市绿地  植物群落结构  物种多样性  重要值

Abstract:This article is aimed at providing scientific evidence and reference for the urban green space planning and the plant diversity construction in Dalian and other cities with similar climatic types. The species composition, community characteristics and species diversity of 105 types and species of plant quadrates around the Dalian city are analyzed. The results show that there are 262 plant species altogether in the investigated quadrates, including 115 arbor species, 50 shrub species and 97 herb species; the proportion of arbor species to shrub species is 1.0 to 0.43; the proportion of evergreen arbor species to deciduous ones is 1.0 to 4.3; and difference exists in diversity level and can be seen in five types of green spaces, in which the general diversity of species can be seen mainly in campuses, residential areas and park green spaces, the species diversity of street and square green spaces takes the second place, and that of the artificial forests is at the bottom.
Keywords:Dalian city  urban green space  structure of plant community  diversity of species  importance value
