摘要：城市森林群落结构研究可为绿色城市、森林城市的建设和发展提供理论依据。通过机械取样和典型抽样相结合的方法对长三角地区城市森林主要群落进行了调查,分析了长三角地区城市森林的植物组成、群落结构以及群落特征的纬度地带性。结果表明:长三角地区城市森林群落样方调查共记录乔木244种,隶属于63科154属;长三角地区城市森林树种分布较集中,城市周边森林和城区森林重要值排名前30位的树种分别占各自重要值总和的70.1%、76.66%;不同纬度带城市森林的物种多样性排序为34°N<32°N<30°N<28°N,常绿落叶比随着纬度的递减从北到南总体呈递增趋势,相同纬度带上针阔叶树种比例从西到东呈逐渐增大的趋势;城市森林的群落结构较为单一,34°N和32°N纬度带城区森林以二球悬铃木(Platanus×acerifolia)和加杨(Populus×canadensis)为基调,而30°N和28°N纬度带主要以香樟(Cinnamomum camphora)为基调;城市周边森林群落遵循自然分布规律,各地树种差异较大,而城区森林群落同质化倾向较明显,地方差异相对较小。
The structural analysis of urban forest communities can provide a theoretical basis for the construction and development of green cities and forest cities. The main communities of urban forests in Yangtze River Delta Region were surveyed by means of mechanical sampling and representative sampling. The latitude zonality of plant composition, community structure and community characteristics of the urban forests was analyzed. In total, 244 tree species were recorded in the surveyed plots, which belonged to 154 genera and 63 families. The distribution of species was relatively concentrated in urban forests of Yangtze River Delta Region. The top 30 species in the urban background forests and urban manmade forests accounted for 70.1% and 76.66% of total importance values, respectively. The order of species diversity of urban forests at different latitudes was 34°N 〈32°N 〈30°N 〈28°N, the ratio of evergreen trees to deciduous trees showed an increasing trend with decreasing latitude, and the ratio of coniferous to broadleaf species was gradually increased from west to east in the same latitude zone. The community structure of urban forests was simple. The main tree species of urban manmade forests were Platanus × acerifolia and Populus × canadensis in zones of 34°N and 32°N, while it was Cinnamomum camphora in 30°N and 28°N. The composition of tree species varied greatly among different urban background forests. However, the tendency of homogeneity was obvious among different urban manmade forests around Yangtze River Delta Region.
