广州市装配式立体绿化景观综合评价分析

Comprehensive Evaluation of Prefabricated Three-dimensional Greening in Guangzhou

基于对广州市越秀、天河、荔湾和海珠4个老城区立体绿化景观现状与生长情况调研,从生态效益、景观美学、抗逆能力、景观成本4个方面构建广州市立体绿化景观综合评价体系,运用层次分析法(AHP)对22个装配式立体绿化景观样点进行评价。结果表明,4个准则层要素中生态效益权重值最大(0.299 1),抗逆能力权重值最小(0.211 6);评价结果为Ⅰ级的景观样点8个,Ⅱ级的14个;景观评价最高的3个立体绿化景观样点是P7、P19、P22,最低的是P5、P8、P1,建议推广应用“3种及以上植物+不同叶色植物+不同叶形植物”的得分较高的设计模式。

Based on the status investigation of application and growth on three-dimensional greening in four old urban districts in Guangzhou, Yuexiu District, Tianhe District, Liwan District, and Haizhu District, a comprehensive evaluation system of three-dimensional greening in Guangzhou is built from the aspects of ecological benefit,landscape aesthetic, resistance capacity and landscape cost, and 22 prefabricated three-dimensional greening landscape sample points are evaluated by using the Analytic Hierarchy Process(AHP). The results show that among the four criterion-level elements, the ecological benefit has the largest weight(0.299 1), while the resistance capacity has the smallest weight(0.211 6). And 8 sample points are rated as Grade I, and 14 are rated as Grade II. Among them, the 3 sample points with the highest landscape evaluation are P7, P19, and P22, and the lowest are P5, P8, and P1. It is recommended to popularize and apply the higher score design patterns of a3 or more plant species + plants with different leaf colors + plants with different leaf shapeso.
