jismart2019004: Composition and Ecological Benefits of Street Trees in Urban Community

Abstract

Urban forest is an important part of urban ecosystem, which provides a lot of ecological, social and economic benefits for the city, and plays an extremely important role in improving the urban habitat environment. Street trees play an important role in maintaining the urban ecological balance and improving the environment. Based on survey data of campus street trees at YuShan Campus of Ocean University of China, the research gave evaluation of the ecological benefit for the study area. The street trees species composition and structural characteristics of urban forest were analyzed. Five factors (energy-saving benefit, storm water retention benefit, quality improvement benefit, CO2 absorption benefit， and aesthetic benefit) were calculated by I-Tree model in order to quantify the ecological benefits of campus street trees, provides a scientific basis for plant selection and plant arrangement, then, provides an important theoretical and practical reference for the construction and development of urban forest.
