大学生生态足迹调查分析——以陕西理工大学(南校区)为例

An analysis of college students' personal ecological footprint——A case study of Shaanxi University of Technology

运用世界自然基金会提供的个人年生态足迹计算软件,通过问卷调查收集陕西理工大学南校区在读本科生个人日常消费与资源占用等相关信息,测算其个人生态足迹,进而分析探讨个人生态足迹和碳足迹的组分及影响因素。结果表明:(1)陕西理工大学南区在读本科生个人生态足迹介于0.30~0.70 hm2,均值0.41 hm2,明显低于国内经济较发达地区高校的生态足迹,生态足迹主要由耕地、水域和能源足迹构成,三者合计占比为91.48%,其中耕地生态足迹占55.40%;(2)个人年碳足迹介于0.14~0.26 t,均值0.20 t,主要由食物和日常用品构成,二者合计占比85.65%;(3)通过分析可知陕西理工大学学生的年级、院系、宿舍楼等对个人生态足迹影响甚微,性别对个人生态足迹有一定影响,表现为男生生态足迹略高于女生,个人的生态足迹与消费水平大小明显正相关。

In this paper,through the questionnaire from Southern campus of Shaanxi University of Technology（ SNUT）,the resources occupation and daily consumption behavior about college students were collected. The paper calculated the personal ecological footprint（ EF） and carbon footprint of the college students based on EF calculator of World Wild Fund for Nature. Through analysis of the component ratio of personal EF and carbon footprint,and comparison of the impact difference of sex,departments,the monthly consumption level on college students＇ EF,the results showed that college students＇ personal EF in SNUT is 0. 30 -0. 70 hm-2 and the average is 0. 41 hm-2,which is relatively smaller than the EF of some colleges and universities from the developed area of China. Cropland,fishing ground and carbon uptake land are the main land use types for students,accounts for 91. 48% of the personal EF. Composition analysis of the carbon footprint concluded that the carbon footprint in SNUT is 0. 14 - 0. 26 t and the average is 0. 20 t. The food proportion of the carbon footprint was 58. 89%,followed by 26. 76% everyday items,the two accounting for 85. 65% of the personal carbon footprint. Through the analysis on the effect of students＇ gender,grade,departments,monthly consumption level,etc on personal EF,it was found that students personal consumption level,living habits were the main factors affecting their personal EF. In order to speed up the green low carbon campus construction,therefore,it is necessary to strengthen the ideological education of college students,prompting them to change the bad habits and build high consumption preference,etc.,thus to reduce the students＇ personal ecological footprint.
