摘要
针对城区景观林存在的群落学问题,研究选择上海城区内分别以广玉兰、香樟、银杏和水杉为优势种的林木群落,建立各类型优势种的盖度梯度,从群落各垂直层次的盖度、高度、优势种胸径和植株密度4方面解析了各群落的结构,筛选和推荐了合理的群落结构,为上海城区景观林的结构优化调整提供借鉴。
A Community structures in each of Magnolia grandiflora, Cinnamomum camphora, Ginkgo biloba, and Metascquoia glyptostroboides dominated forests were analyzed against the shortages cxisting among these four typical landscape forests in Shanghai. Community coverage, vertical height, diameter at breast height and individual density in each of tree, shrub and herb layers were compared along a gradient of dominated tree coverage for the four typical forests respectively. Then opthnal community structure was recommended as a reference to improvc community structure in the Shanghai.
