基于AHP的济南地区城市骨干乔木类树种的选择评价

The Selection and Evaluation of Urban Diaphysis Arbor Tree Species Base on AHP in Jinan City

骨干树种选择,是我国城市绿化建设过程中,树种规划的一项研究内容。在对北方城市和济南地区城市骨干乔木类树种应用现状进行全面调查基础上,采用层次分析法对济南地区的城市骨干乔木类树种的适宜性进行综合评价,建立了定性与定量相结合的综合评价层次结构模型。评价结果表明:Ⅰ级(≥2.5),综合评分很高的种类,共3种;Ⅱ级(2.0~2.25),综合评分较高的种类,共10种;Ⅲ级(≤2.25),综合评分一般的种类,共6种。参考AHP的综合评价及各层次评价结果,推荐了13种适宜济南地区城市骨干乔木类树种。

The selection of diaphysis tree species is a research content based on the tree species planning in the process of urban greening construction in our country.On the basis of comprehensive investigation on the application status of diaphysis arbor tree species in northern cities and Jinan,the AHP was used to evaluate the landscape value of diaphysis arbor tree species in Jinan area,and the comprehensive evaluation model of landscape value was built.The evaluation results show that:level I(≥2.5),species score higher in the comprehensive landscape evaluation,a total of 3;level I(2.0~2.25),species score highest in the comprehensive landscape evaluation,about 9;level II(≤2.25),species that are general in the comprehensive landscape evaluation,about6.Consulting the AHP comprehensive evaluation and results of each level,the authors recommend 12 diaphysis tree species which are suitable to be used in Jinan area.
