Characteristics of Trees Collocation and Community Structure on Urban Forest in the Parks Around Hefei City

本文应用植被研究方法,采用样方调查资料来分析环城公园的树种构成、树木的高度及径阶分布、健康状况,并通过计算主要组成树种的生长指数,种间关联度来揭示群落构成的特点。结果表明环城公园群落结构比较复杂,有22对组成种表现正相关,其中侧柏-红叶李-桂花,刺槐-女贞,刺槐-银杏-石楠,加杨-女贞-桂花,中槐-女贞-黄杨,青冈-蚊母的组合中树木的生长良好,群落结构也比较稳定,

The parks around Hefei city have the typical characteristics of urban forest. The study methods of vegetation ecology were used to analyze the community structure and species composition, distribution pattern of tree height and dbh were described in this paper. Through calculation of tree growth index and correlation of component species in parks around the city, the community structures of urban forest were analyzed. The resultsshowed that community structures of parks around city are complex, there are 22 species partnership with positive association, and tree individuals in the following communities grows well and the community structures are more stable. They are mainly Platycladus orientalis & Prunus cerasifera f.
