为营造物种多样、季相丰富、景观优美的生态经济型花镜,筛选出一批适合于华南地区花镜景观营造的植物种类,并采用层次分析法进行综合评价。结果表明,适合华南地区花镜景观营造的植物305种,隶属于84科221属,主要有爵床科(Acanthaceae)、豆科(Fabaceae)、菊科(Asteraceae)、石蒜科(Amaryllidaceae)等,小乔木、灌木、草本和藤本植物分别有16、127、134和28种;乡土植物100种,占32.79%,外来植物205种,占67.21%。综合评价分析表明,Ⅰ级、Ⅱ级和Ⅲ级花镜植物分别有148、151和6种;层次分析表明,前景植物、中景植物和背景植物分别有106、162和157种;季节分析表明,春、夏、秋和冬季植物分别有216、232、195和128种。这表明可用于华南地区花镜景观营造的灌木和草本植物资源丰富,应用形式多样。

In order to construct the ecological and economical flower mirror with diverse species,rich season-colors,and beautiful landscape,a batch of plant species,which suitable for flower mirror landscape in South China,was selected and evaluated by analytical hierarchy process(AHP).The results showed that 305 species were picked out,belonging to 84 families and 221 genera,mainly in Acanthaceae,Fabaceae,Asteraceae,Amaryllidaceae,etc.According to life-form,there are 16,127,134 and 28 species of small trees,shrubs,herbs and vines,respectively.There were 100 native species and 205 alien species,accounting for 32.79%and 67.21%,respectively.Comprehensive evaluation showed that Grade I to III had 148,151 and 6 species,respectively.The layer analysis indicated that 106,162 and 157 species were foreground,mid-shot and background plants,respectively.As for seasonal selection,216 species are good for spring,232 species for summer,195 species for autumn,and 128 species for winter.Therefore,the rich resources of shrubs and herbaceous plants with various forms provide numerous design ideas for flower mirror in South China.
