摘要
由于城市环境的特殊性,城市绿化的参与者同时也是绿化树种选择的决策者,城市绿地树种结构的初始分布完全由人为选择控制。现阶段受人为因素干扰,城市绿地表现出的诸如树种优势度集中、结构单一、生态效益低下等问题越来越突出,使得从参与者角度探明城市绿地树种选择的主观影响因素变得十分重要。通过建立城市绿地树种选择影响因素评价指标体系,让政府主管部门、规划设计者、绿化施工企业、苗木供应者及市民公众5类绿化参与者对树种选择影响因素进行评价,再运用SPSS 23.0软件对5类绿化参与者的评价结果进行相关性分析,并从参与者角度对合肥市常见园林绿化树种进行综合评价。结果表明:(1)不同参与者对城市绿地树种选择影响因素重要性的判断不同;(2)政府主管部门与规划设计者对城市绿地树种选择影响因素的权重评价数据在0.01水平上呈显著相关,与绿化施工企业在0.05水平上呈显著相关;(3)根据绿化参与者的权重数据对合肥市常见园林绿化树种进行综合评价,筛选出不同参与者综合评价在3.0分以上的树种154种,其中Ⅰ类树种51种、Ⅱ类树种44种、Ⅲ类树种59种。
Because local participants of an urban greening project were not the decision makers for tree species selection, the initial tree distribution in an urban green space was completely controlled by artificial selection resulting in problems such as concentration of dominant tree species, simple structure, and low ecological benefits. To show that inclusion of local participants was very important in remedying problems of urban tree species selection, in this study, influential factors for urban tree species selection were picked and an evaluation index system was established with input from government employees, designers, green development enterprises, suppliers, and the public. Then a correlation analysis between these local participants was analyzed by SPSS, and a comprehensive evaluation on common tree species from the point of view of these local participants was accessed using Hefei City as the test site. Results showed that（1） judgment of urban tree species selection influential factors differed among the local participants.（2） Evaluation data of weighted values for urban tree species selection between government departments and designers was highly significant（P = 0.01） and was correlated（r=0.852） and between government departments and green development enterprises was significantly correlated（P=0.05, r=0.590）.（3） According to the weighted values, the comprehensive evaluation of common landscape tree species in Hefei City was accessed with 155 tree species scoring above 3.0 being selected. This classification provided new ideas and suggestions on urban tree species selection.
