合肥市城市道路绿化行道树配植模式的研究

调查分析了合肥市二环内38条道路的城市道路绿化配置模式，结果表明：合肥市道路绿化配植模式有：一板二带式，二板三带式，三板四带式和四板五带式，其中以一板二带式和三板四带式为主，分别占调查道路总数的42％和46％，二板三带式和四板五带式仅占5％和7％；行道树现有树种22种，隶属16科20属，以香樟、广玉兰、悬铃木、国槐、女贞为主。根据现状，并借鉴其它城市道路绿化配植成功的模式，依据不同的道路性质、走向、人行道宽度和断面结构，提出新的道路绿化配植模式和行道树，为今后合肥市及其周边城市道路绿化设计提供参考。

Study on planting arrangement model of roadside trees in Hefei

Planting arrangement of road afforestation in 38 paths of Hefei city areas investigate and analysised. The result showed that there are 4 patterns of match plants, including single carriageway with two green belts, dual carriageways with three belts, three carriageways with four belts, four carriageways with five belts, the dominant patterns are single carriageway with two green belts and three carriageways with four belts, which are occupied 42% and 46% respectively. The dual carriageways with three belts and the three carriageways with four belts are occupied 5% and 7%. There are 16 families, 20 generas and 22 species roadside trees, the dominant species are Cinnamomum camphora , Magonolia grandiflora , Platanus acerifolia , Sophora japonica , Ligustrum lusidum. The new planting arrangement model and roadside trees are put forward basis for the different culture ,trend ,the width of the footway and the section structure, which according to the existing conditions and using the successful planting arrangement model of the other cities for reference. We hope it can give reference for planting arrange the road afforestation planting arrangement model of hefei and the surrounding cities .
