基于城市森林廊道构建技术研究需要,本文研究了成都市沙河森林廊道的群落结构特征,群落组成简单,树种单一,但观赏性强,可能与游憩功能有关;树木多以中小径级为主,大径级比例较小,高度偏低,主要受培育时间的影响。乔木的丰富度指数为6.02,灌木为9.78,草本为9.63,总体数量明显受到灌草层影响较为明显。群落多样性在3～4之间,与种类少,分布不均有关。较大的三维绿量有较大的叶面积指数,树种选择需要考虑高叶面积指数树种。在技术上,建议河流森林廊道建设优化与管护时,多采用珍稀濒危种类,且配置复层结构,增大林带规模与近自然化程度。

In this paper,based on the requirement for studying the structure techniques of urban forest corridor,researches were conducted on the community structure characteristics of forest corridor in the Shahe river of Chengdu city.The result showed that it was a simple community structure with a single tree species composition,but had a good ornamentation,which could be related to the recreation function.The trees were mainly media and small diameter classes,with the proportion of the big diameter class being less,and their height was relatively low,which could be mainly affected by the cultivated time.Abundance indice of arbor,shrub and grass respectively were 6.02,9.78 and 9.63,and total amounts were obviously controlled by shrub and grass layers.Diversity of community was between 3 and 4,relatively lower compared to evergreen broad-leaved forest,which was related to small species kinds and uneven distribution.Bigger three dimensional green quantity had a bigger leaf index and bigger leaf area index should be considered in tree species selection.From techniques,it was suggested to adopt the rare and endangered tree species,allocate the multiplied structure,add the forest zone size and increase the degree of near nature forest when the optimized establishment and management of river forest corridor were conducted.
