摘要
为了解上海城市森林群落和森林植被分布状况,为城市森林经营管理提供参考,采取样地调查法在上海城市森林设置95个群落样方进行调查.结果表明:(1)上海城市森林可划分为针叶林、常绿阔叶林、常绿落叶阔叶混交林、落叶阔叶林和竹林等5种类型共16个森林群落.(2)上海城市森林中有维管植物121种(含种下等级和栽培种),隶属于58科111属.(3)植物地理成分较复杂,科的地理成分以热带性质为主,属、种的地理成分以温带性质为主;温带性质的属共有42个,热带性质的属共有29个,具有较强的热带、亚热带向温带过渡的性质.上海城市林业以人工林为主,且大部分林分处于中幼林阶段,以常绿阔叶林最为典型.
Abstract
The distribution characteristics of urban forest communities and vegetations in Shanghai were studied based on a survey of 95 community plots,providing scientific basis and references for urban forest management.The results demonstrated that:(1)16 forest communities were divided into 5 types,namely as needle-leaved forest,evergreen broad-leaved forest,evergreen and deciduous broad-leaved forest,deciduous broad-leaved forest and bamboo forest;(2)121 species vascular plants(including grades of lower species and the cultivated plants)were recorded in urban forest of Shanghai,belonging to 111 genera in 58 families;(3)The phytogeographic composition of the urban forest in Shanghai was complex,the geographical composition of the family was mainly tropical,while the physical composition of genera and species was mainly temperate with 42 genera of temperate nature and 29 genera of tropical nature,delivering strong transitional properties from tropical and subtropical to temperate.The urban forests in Shanghai are dominantly artificially planted with most of the stands in young-middle ages,and the most typical type is evergreen broad-leaved forest.
