上海海湾国家森林公园1 hm2样地群落结构特征及其动态监测意义
Characteristics of Plant Community Structure in a 1 hm2 Lot of the Haiwan National Forest Park of Shanghai and the Significance of Its Dynamics Monitoring
摘要
Abstract
A long-term monitoring of community structure and its dynamics of urban forests using the permanent plotbased approach may help reveal development direction and intrinsic mechanism of the forest community.A 1 hm2 lot was set up in the Haiwan National Forest Park,Shanghai,in 2011.Survey was made of the plot and record kept of all the species of plants in the plot,particularly arbors taller than 1.3 m,for analysis of species composition,floristic elements,and vertical and horizontal structures of the community.Results show that a total of 73 species of vascular plants were recorded,belonging to 68 genera and 31 families.Of the 68 genera,51.8％ were of the temperate flora and 46.4％ of the tropical one.Arbor individuals taller than 1.3 m reached 3 094,of which 1 670 individuals were evergreen trees of 6 species,accounting for 48.0％ in community importance,while the remaining 1 424 individuals,deciduous trees of 7 species,accounting for 52.0％ in importance.The six species,i.e.Ligustrum lucidum,Camptotheca acuminata,Photinia davidsoniae,Sapium sebiferum,Koelreuteria integrifoliola,Cinnamomum camphora,were in the top of the list in importance,forming a hierarchic structure,vertically.At a 0-50 m scale,L.lucidum trees were distributed in groups,C.acuminata trees in an even-random-group pattern,P.davidsoniae and S.sebiferum trees in a group-random-even pattern,and K.integrifoliola and C.camphora trees in a random-group-random pattern.In terms of characteristics of population structure,the plot was a patch of evergreen and deciduous broad-leaved mixed forest dominated with north temperate and pantropic floristic elements,which characterized structure of the natural vegetation of the plot.The establishment of such long-term monitoring sample plots may provide data for following origin,development and succession of urban forests on urbanized plain area of the Yangtze River Delta.关键词
