摘要
Since the sustainable development has been widely acknowledged worldwide,the sustainable campus development based on low-carbon campus construction has already become a tendency of building resource-saving and environment-friendly society.It is a hot and difficult topic in the current campus planning to measure,estimate and construct low-carbon campuses.This paper calculated the ecological footprint of traffic,water,energy and daily life on the campus of Peking University Shenzhen Graduate School,obtained the energy consumption of each item on campus and individual low-carbon activities using questionnaire survey and interview,compared the data with those of other domestic and foreign campuses.The results showed that(1) Ecological footprint of Peking University Shenzhen Graduate School in 2016 was 4,269 hm^2,and per capita ecological footprint was 1.49 hm^2;(2) Total carbon emission in 2016 was 13.4×107 kg,among which power generation and food produced the most carbon emission;(3) Students had strong awareness of low-carbon life,and the main obstacles for low-carbon life were "Hard to change living habits","Greedy vanity",and "No efficiency instruction";(4) In terms of the overall proportion,control of energy consumption is the main approach of reducing campus carbon emission,which is similar to other domestic and foreign campuses.The carbon emission of daily life in Peking University Shenzhen Graduate School was significantly higher than that of foreign campuses,while that of traffic was lower.Suggestions and improvement measures were put forward in view of the existing problems.
