Evaluation of ecological benefits of street trees in different functional areas of Jinggangshan University campus
摘要
Abstract
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.关键词
