摘要
Several quantitative and qualitative indexes were selected for road landscaping in universities, Analytic Hierarchy Process (AHP) was applied to construct an evaluation system for the selection of road landscaping trees for universities. Such an evaluation system was also used to objectively and comprehensively appraise present ornamental tree species in Binzhou University, and select species fit for its road landscaping, plant furnishings in Binzhou University were also analyzed.
[目的]构建高校道路观赏植物树种筛选的评价体系,为高校绿化工作提供量化评价方法。[方法]选择若干针对高校道路观赏植物的定性指标和定量指标,采用层次分析法(AHP法)构建高校道路观赏植物树种选择评价体系。结合滨州学院自身特点,制定了3个1级指标,13个评价因子,即:①生存适应性指标(B1):耐旱性(C1)、耐寒性(C2)、抗污染性(C3)、耐碱性(C4)、抗病虫能力(C5);②生态生理特性指标(B2):生长速度(D1)、寿命长短(D2)、根系深度(D3)、绿色期长短(D4)、需光性(D5);③观赏和管理指标(B3):冠幅与枝叶繁茂程度(E1)、树姿美观性(E2)、耐修剪性(E3)。采用德尔菲法和AHP法相结合,构建量化判断矩阵和计算权重,并应用该评价体系对滨州学院校园观赏植物树种进行了客观全面地评价。[结果]15种校园现有的植物树种配置综合得分最高的为法国梧桐(92.53,满分为100),最低的为毛白杨(78.03);道路两旁栽种效果较好的有法国梧桐、银杏、刺槐、栾树、垂柳和白腊。[结论]通过AHP评价结果与实际种植效果比较认为,滨州学院的道路观赏植物配置总体较为合理,比较结果同时也验证了该评价体系是科学和准确的。
