基于AHP法的成都市公园花境综合评价

Landscape Evaluation of Chengdu Park Flower Border based on AHP

以成都市公园花境为研究对象,采用层次分析法(AHP法)以美学价值、生态价值、服务价值3个方面作为准则层,建立花境景观综合评价体系。结果表明:(1)准则层权重值美学价值(0.5382)>生态价值(0.3533)>服务价值(0.1085);(2)指标层中植物观赏特征多样性(0.1365)、植物物种丰富度(0.1185)、层次丰富度(0.1170)位列权重值的前3位;(3)花境景观综合评价结果为Ⅱ级花境35个,Ⅲ级花境5个,无Ⅰ级、Ⅳ级景观,景观质量总体较好,但缺乏优秀花境景观。

Taking the flower border of Chengdu Park as the research object, the comprehensive evaluation system of flower border is established by using analytic hierarchy process(AHP) and taking the three aspects of aesthetic value, ecological value and service value as the criterion level.The results show that:(1) the weight value of criterion layer is aesthetic value(0.5382) > ecological value(0.3533) > service value(0.1085).(2) In the index layer, the diversity of plant ornamental characteristics(0.1365), plant species richness(0.1185) and hierarchical richness(0.1170) ranked among the top three of the weight values.(3) The comprehensive evaluation results of flower border landscape are 35 grade Ⅱ flower borders and 5 grade Ⅲ flower borders. There are no grade Ⅰ and Ⅳ landscapes. The overall landscape quality is good, but there is a lack of excellent flower border landscape.
