基于AHP法的城市开发区道路植物景观评价体系构建——以广州开发区黄埔区为例

Establishment of Plant Landscape Evaluation System for Urban Road Based on Analytic Hierarchy Process——Taking Huangpu District in Guangzhou as an example

城市道路植物景观是构建城市自然生态环境的基石,是人们对城市整体植物景观的第一印象,也是对城市形象的直观展现。采用层次分析法(AHP法)构建客观适宜、有针对性的城市道路植物景观评价体系,从定性(主观认识)和定量(客观计量)2个方面,选择植物丰富度、观赏特性多样性、景观时序多样性、地带特性、物种适应性、植物景观空间多样性、与整体环境的协调性、植物配置艺术性、管理养护、生态功能等10个评价因子,运用"1~9标度法"构造判断矩阵,借助yaahp软件计算各层次指标权重并检验其正确性;为检验该评价体系的可行性,选择广州开发区黄埔区36组具有代表性的城市道路植物景观为样例进行评价,结果显示,该评价体系能够实际反映城市道路植物景观建设水平的高低,具有一定的理论价值。

Abstract ： Urban road plant landscape is the cornerstone of constructing urban ecological environment, which is not only the peopleg first impression of the whole city landscape, but also a visual presentation of the city. An objective and suitable urban road plant landscape evaluation system has been constructed by use of AHP method, about ten evaluation factors have been chosen from the qualitative （subjective） and quantitative （ objective measurement） as- pect, such as plant species richness, diversity of ornamental characteristics, landscape timing diversity, zone char- acteristics, species adaptability, plant landscape spatial diversity, harmony with the whole environment, plant con- figuration art, management and maintenance and ecological function, and 1 -9 scale method is used to construct the judgment matrix, calculate the weight of each index by Yaahp software and verify its correctness. In order to test the feasibility of the evaluation system, 36 groups of representative urban road plant landscape from Huangpu District in Guangzhou have been chosen to evaluate. the level of urban road plant landscape construction. The results show that the evaluation system can actually reflect
