基于层次分析法的武汉市综合性公园植物景观评价

Evaluation of plant landscape in Wuhan comprehensive park based on AHP

为探究城市综合性公园植物景观评价方法,选取武汉市8个典型的综合性公园,160个植物群落。利用层次分析法(AHP法),选取11个定量和定性指标,建立城市综合性公园植物景观综合评价体系,体系涉及植物群落的生态功能、美学功能、服务功能三个方面。研究结果显示:人们更加重视植物群落的生态功能,其权重值为0.540,其次是服务功能、美学功能,权重值分别为0.250和0.210。其中7个公园处于Ⅰ级、Ⅱ级,只有1个公园处于Ⅲ级水平,市级综合性公园综合景观质量优于区级综合性公园。这与公园定位和现状相符,说明评价体系能够客观的评价城市综合性公园的植物景观质量。

In order to study the realization of plant landscape quality in urban comprehensive park.The study selected eight typical comprehensive parks and 160 plant communities in Wuhan.Based on the analytic hierarchy process(AHP),11 quantitative and qualitative indexes were selected to establish the comprehensive evaluation system of plant landscape of urban comprehensive park,which related to the ecological function,aesthetic function and service function of plant community.The results show that The ecological function of the plant community is paid more attention,and its weight is 0.540.Followed by the service function,aesthetic function,weight values are 0.250 and 0.210 respectively.Seven of the parks are in gradeⅠandⅡ,only one park at level III,City-level comprehensive park is superior to district-level comprehensive park.This is consistent with the positioning and status of the park,indicating that the evaluation system can objectively evaluate the quality of the plant landscape in urban comprehensive parks.
