基于AHP的柳州市居住区植物景观评价体系构建

摘要

By taking the plant landscapes in residential area in Liuzhou city as the research subjects, 30 plant landscape units were selected as the evaluation plots, and evaluated by using analytic hierarchy process (AHP), and a landscape plant assessment model was established. The results were as follows:in the criterion level weights, the ecological function score (y1=0.539 6) was the highest score, followed by the aesthetic function score (y2=0.297 0), next was the services function score (y3=0.163 4);in the index level weights, the top ifrst four were:the coordination and symbiotic between the plants score was the highest score (X4=0.244 1), followed by the diversity of life forms score(X3=0.172 6), the variation of colors and seasonal aspects score(X6=0.119 4), and the diversity of ornamental characteristics score(X5=0.088 6);the comprehensive scores of 30 plant landscape units were all between 6.7~7.96.7, which showed that the plant landscapes in Liuzhou residence were good. Based on the evaluation results, eight good plant arrangement modes that have some practical signiifcance were recommended.%以柳州市居住区为研究对象，选取其中30个植物景观单元作为评价样方，运用层次分析法（AHP法）进行评价，以构建居住区植物景观评价体系。结果表明，准则层权重值排序为生态功能Y1（0.5396）＞美学功能Y2（0.2970）＞服务功能Y3（0.1634）。指标层前四位权重值排序为植物间的协调共生性X4（0.2441）＞植物生活型多样性X3（0.1726）＞植物色彩与季相变化X6（0.1194）＞植物观赏特性多样性X5（0.0886）。30个样方的综合评分值均在6.7～7.9分之间，这表明柳州市居住区植物景观总体较好。基于评价结果，推荐了8个优秀的植物景观配置模式，具有一定的实践指导意义。
