基于AHP法的郑州城市公园康养景观评价

Healthy Landscape Evaluation of Urban Parks in Zhengzhou City Based on AHP

以郑州市人民公园为对象,应用层次分析法,通过6个准则层因素和30个指标层因素来研究影响城市公园康养景观的重要景观因素。结果表明:1)准则层的权重由大到小排序为:安全性B_(1)(0.3550)、健康性B_(2)(0.2320)、生态性B_(5)(0.1503)、人文关怀B_(6)(0.1336)、便捷性B_(4)(0.0828)、舒适性B_(3)(0.0464);2)指标层的重要性程度中最高值和最低值分别为:B_(1)的空间布局的安全性(0.3592)、植物品种的安全性(0.0615),B_(2)的疾病预防(0.4481)、增强体力(0.0722),B_(3)的空间尺度的舒适性(0.3337)、色彩的舒适性(0.0302),B_(4)的空间的可达性(0.4732)、交通的合理性(0.1220),B_(5)的景观多样性(0.4796)、物种多样性(0.1150),B_(6)的无障碍设施的人性化(0.4813)、标识系统的人性化(0.0979);3)人民公园的综合评分为3.6897,评级为“良”。该研究为今后科学系统地进行城市公园康养景观评价提供参考依据。

Taking Zhengzhou People's Park as an example,this paper studied the important landscape factors affecting the Healthy Landscape of the park through six criterion layer factors and thirty indicator layer factors by using the analytic hierarchy process(AHP).The results showed that 1)weight ranking of the criterion layer was safety B_(1)(0.3550),health B_(2)(0.2320),ecology B_(5)(0.1503),humanistic care B_(6)(0.1336),convenience B_(4)(0.0828),comfort B3(0.0464).2)The highest and lowest importance evaluation indicators of each indicator layer were B_(1):security of spatial layout(0.3592),safety of plant varieties(0.0615);B_(2):(rehabilitation)disease prevention(0.4481),strength building(0.0722);B_(3):comfort of spatial scale(0.3337),comfort of color(0.0302);B_(4):accessibility of space(0.4732),rationality of traffic(0.1220);B_(5):landscape diversity(0.4796),species diversity(0.1150);B_(6):humanization of accessibility(0.4813),humanization of identification system(0.0979).3)The comprehensive score of the People's Park was 3.6897,which indicated that the effect of healthy landscape was better.This study provides a reference for the scientific and systematic evaluation of Urban Park healthy landscape in the future.
