摘　　要：为了对植物群落的景观质量进行综合评价，选取21项评价指标并运用因子分析权数法确定了其权重系数，变幅为0.0184～0.0846，其中色彩丰富度（0.0846）的权重最高，草本高度（0.0184）的权重最低。以北京市5个郊野公园中的16个植物群落为研究对象，利用灰色关联分析法确定其与“理想植物群落”的关联度，并对植物群落的景观质量进行综合评价。结果表明，基于加权法的关联度变幅为0.4404～0.6633，其中毛白杨＋白蜡群落（γ＝0.6633）、银杏群落（γ＝0.6296）、毛白杨群落（γ＝0.6246）和刺槐群落（γ＝0.5645）的综合表现最好；杜仲、垂柳及油松3个群落表现最差。In order to evaluate landscape quality of vegetation community,twenty-one appraisal indexes were selected and analysed by method of the factoranalysis weight.The weight coefficients varied from 0.018 4 to 0.084 6and the highest weight coefficient was color richness（0.084 6）,while the lowest weight coefficient was herb height（0.018 4 ）.Landscape quality of sixteen vegetation communities in five Suburban Parks of Beijing was evaluated by gray relational analysis method.The result showed that the correlation degrees varied from 0.440 4 to 0.663 3.Populus tomentosa ＋Fraxinus chinensis Comm.（γ=0.663 3）,Ginkgo biloba Comm.（γ=0.629 6）, Populus tomentosa Comm.（γ=0.624 6）and Robinia pseudoacacia Comm.（γ=0.564 5）were the closest to the i-deal vegetation community,while Eucommia ulmoides Comm.,Salix matsudana and Pinus tabuleeformis Comm. were the worst.
