| 在节能减排背景下，量化校园不同功能区行道树的生态效益，可为校园绿色发展提供重要参考。本研究将校园划分为林区、休闲活动区、学生宿舍区、教工生活区、行政区和教学区6类功能区，并对各区内行道树进行了每木调查和生态效益评估。结果发现：行道树总计2 086株，隶属11科12属12种。行道树的年总生态效益为791 240.99元，其中美学效益（538 446.95元，占比68.05%）居首。其次为截留雨水效益（148 350.65元）、节能效益（84 806.96元）和吸收CO2效益（22 886.11元），而空气质量效益为负值（-3 249.68元）。从功能分区看，休闲活动区的行道树数量及总效益最高（占比43.23%），其余区域依次为学生宿舍区、行政区、教学区、教工生活区和林区。从树种贡献看，香樟形成的总效益最高（占比62.74%），其次为二球悬铃木（占比28.12%），其余10种行道树合计仅占比9.14%。优化建议：研究区内行道树种类相对单一，但多数行道树处于稳定生长阶段，建议结合功能区属性适当调整行道树的树种配置，以提升校园生态环境质量。 |

| Under the background of energy conservation and emission reduction, effectively quantifying the ecological benefits of campus street trees in different functional areas can provide important references for the green development of campuses. The research area is divided into six functional areas, including forest area,leisure activity area, student dormitory area, faculty living area, administrative area and teaching area, and each street tree is investigated. The ecological benefits of street trees in each area are evaluated. A total of 2 086 trees were examined during the survey, which included 12 species belonging to 11 families and 12 genera. The annual total benefit value of the street trees is 791 240.99 yuan, of which the aesthetic benefit is the highest（538 446.95 yuan）, accounting for 68.05% of total benefits. The remaining benefits are 148 350.65 yuan for rainwater interception, 84 806.96 yuan for energy conservation, 22 886.11 yuan for CO2 absorption, and -3 249.68 yuan for air quality. From the perspective of functional area, the number of the street trees in the leisure activity area is the largest and the total benefit value is the largest, accounting for 43.23% of total benefits. The rest are in turn the student dormitory area, administrative area, teaching area, faculty living area and forest area. In terms of the street tree species, Cinnamomum camphora has the highest total benefit, accounting for 62.74% of the total benefit,followed by Platanus acerifolia accounting for 28.12%, and the other 10 street trees accounting for only 9.14%.Optimization suggestion: The types of the street trees in the study area are relatively single, and most street trees are in a stable growth stage. In the future, the types and proportions of the street trees can be appropriately adjusted according to the attributes of different functional areas of the campus, so as to further improve the quality of the campus ecological environment. |
