基于AHP的柳州市居住区植物景观评价体系构建

Establishment of plant landscape evaluation system for residential area in Liuzhou city based on Analytic Hierarchy Process

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（0.539 6）＞美学功能Y2（0.297 0）＞服务功能Y3（0.163 4）。指标层前四位权重值排序为植物间的协调共生性X4（0.244 1）＞植物生活型多样性X3（0.172 6）＞植物色彩与季相变化X6（0.119 4）＞植物观赏特性多样性X5（0.088 6）。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。

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 fi rst 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 signifi cance were recommended.
