摘要: 本文运用i-Tree模型对青岛市南区的行道树组成体系进行分析,统计并量化了2012年青岛市市南区内行道树截留雨水、CO2吸收和固碳、改善空气质量、节能等生态效益的经济价值。结果表明:市南区主要道路有行道树43种,共计12322株,其中悬铃木、银杏等10种主要树种占整个行道树树木总数的84.4%;行道树胸径径阶分布主要以中(DBH为15~30 cm)、小(DBH<15 cm)胸径为主,分别占53.54%、29.06%;行道树总体健康状况良好,健康树木占总数的97.4%;市南区行道树年生态效益价值2303.2万元,单株行道树加权平均效益为1869元。本研究可为城市行道树种植规划提供参考。

Abstract: In this paper, the i-Tree Model was applied to analyze the composition of the street trees in Shinan District of Qingdao, and to quantify the economic value of the street trees’ ecological benefits in storm water interception, CO2 absorption and sequestration, air quality improvement, and energy saving in 2012. On the main roads of the District, there were 12322 individuals of 43 street tree species, among which, the top 10 species such as Platanus spp. and Ginkgo biloba accounted for 84.4% of the total. Mediumsized (DBH: 15-30 cm) and smallsized (DBH<15 cm) trees dominated the street trees, occupying 53.54% and 29.06%, respectively. Overall, the street trees were in good health condition, and the healthy trees occupied 97.4% of the total. The annual economic value of the street trees’ ecological benefits was 23032 thousand yuan, and the weighted average benefit of an individual tree was 1869 yuan. This study could offer helpful and scientific references on the planning and planting of urban street trees and the management of urban landscape.
