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。
為瞭對植物群落的景觀質量進行綜閤評價，選取21項評價指標併運用因子分析權數法確定瞭其權重繫數，變幅為0.0184～0.0846，其中色綵豐富度（0.0846）的權重最高，草本高度（0.0184）的權重最低。以北京市5箇郊野公園中的16箇植物群落為研究對象，利用灰色關聯分析法確定其與“理想植物群落”的關聯度，併對植物群落的景觀質量進行綜閤評價。結果錶明，基于加權法的關聯度變幅為0.4404～0.6633，其中毛白楊＋白蠟群落（γ＝0.6633）、銀杏群落（γ＝0.6296）、毛白楊群落（γ＝0.6246）和刺槐群落（γ＝0.5645）的綜閤錶現最好；杜仲、垂柳及油鬆3箇群落錶現最差。

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.
