漳州市城市道路绿化树种选择与综合评价

Selection and Comprehensive Evaluation of Tree Species for Urban Road Greening in Zhangzhou City

  • 摘要: 为合理评价及选择漳州市城市道路绿化树种,对典型性城市道路进行实地调查,并采用层次分析法(Analytic Hierarchy Process,AHP),经专家问卷方式对5大准则、16个指标进行评价模型构建。结果表明,52条城市道路共有绿化树种79种,隶属27科58属,主要以豆科(Leguminosae)及棕榈科(Palmae)植物为主,应用频度最高的是秋枫(Bischofia javanica)与小叶榕(Ficus concinna)。在16个指标中,观叶指标权重最高,其次依重要度排序为耐寒性、观花、滞尘、抗风性等。对16个指标的分级评分标准进行细化,并运用评价模型对所调查的79个树种进行综合评价,得到I级树种9个,II级树种28个,III级树种34个,IV级树种8个。研究结果可为漳州市城市道路建设项目合理选择基调树种、骨干树种及一般树种提供参考;同时该评价体系模型也为乡土树种的开发利用及外来品种引进提供有益参考。

     

    Abstract: To reasonably evaluate and select tree species for urban road greening in Zhangzhou,a field survey of typical urban roads was conducted. The Analytic Hierarchy Process (AHP) was used to construct an evaluation model based on expert questionnaires,covering 5 major criteria and 16 indicators. The results showed that there were 79 tree species on 52 urban roads,belonging to 27 families and 58 genera,mainly Leguminosae and Palmae plants. The most frequently used ones were Bischofia javanica and Ficus concinna.Among the 16 indicators,the highest weight was given to foliage,followed by cold resistance,flowering,dust retention,wind resistance,and others in descending order of importance. Detailed grading standards for the 16 indicators were developed,and the evaluation model was applied to comprehensively assessing 79 surveyed tree species. This assessment identified 9 species as Grade I,28 species as Grade II,34 species as Grade III,and 8 species as Grade IV. This provides a reference for the rational selection of essential,main,and general tree species for urban road construction projects in Zhangzhou. The evaluation system model also offers valuable reference for the development and utilization of native tree species and the introduction of exotic varieties.
