【摘要】：人类社会的发展导致地球的环境发生了巨大的改变,气候变暖成为了全球必须共同面对的问题。森林是陆地生物圈的最主要组成部分,是陆地碳库的重要来源,调节着全球碳平衡。校园中的绿化带及各植被类型构成了城市绿地的重要组成部分,肩负着维持校园生态系统及周边环境碳源、汇平衡的重要作用。随着国家教育产业的大力发展,高校成为了重要的能源消耗大户,继而成为城市生态系统中的碳源大户。因此,通过校园生态系统碳源、汇的计量研究,对于有效、合理地评估绿色校园、低碳校园,并持续推动低碳校园建设具有重要意义。通过以下方面对校园碳源、汇进行了计量和分析:(1)对校园绿地类型的调查和碳储量估量,获取了校园植被碳库的第一手资料;(2)通过随机问卷式调查,获取了全校师生资源消耗和碳足迹数据;(3)通过收集、分析2011~2013年度全校水、电、天然气等资源的消耗,评估了校园日常消耗的公共碳足迹。这些都是校园碳源、汇计量的基础,是校园碳源、汇分析,建设低碳校园的必要前提。主要研究结果有以下几个方面。1、共调查校园乔木树种91种,3533株。选取适用于本研究乔木生物量估算的全组分幂函数异速生长方程共5组、20个。安徽农大校园乔木树种生物量为1988.93 Mg,碳储量为994.46 Mg。2、共调查校园内代表性的灌木树种13种,35株(丛),并对校园内道路绿篱进行了体积测量。利用灌木生物量估算的混合物种全株幂函数异速生长方程计算,得到安徽农大校园灌木树种生物量为690.09Mg,碳储量为289.77 Mg,其中大学生公寓灌木生物量密度为3.16kg/m2安徽农大校区灌木生物量密度为1.09kg/m2。3、根据问卷调查,安徽农大教职工人均二氧化碳排放量为1.56 Mg/a,转换为净碳排放为0.43 Mg/a,年均碳排放量为777.00 Mg/a;学生人均二氧化碳排放量为0.47 Mg/a,转换为净碳排放为0.13 Mg/a,年均碳排放量为2710.66 Mg/a。安徽农大校园植被中的乔木、灌木作为主要的光合生物类型,承担着吸收二氧化碳,从总体上减少校园碳排放的任务,是校园中最主要的生物量碳库。教职工、学生和全校公共水、电消耗,构成了校园主要的碳足迹。安徽农大校园是一个巨大的碳源,校园绿地植被的碳汇功能还有巨大的潜力,通过加大校园各类植被的管理和优化合理配置,校园绿地的碳汇功能还会进一步提高。
[Abstract]:With the development of human society, the environment of the earth has changed greatly, and global warming has become a common problem. Forest is the most important component of terrestrial biosphere and an important source of terrestrial carbon pool, which regulates the global carbon balance. The greenbelts and vegetation types in the campus constitute an important part of the urban green space and play an important role in maintaining the carbon source and sink balance of the campus ecosystem and the surrounding environment. With the development of national education industry, colleges and universities have become important consumers of energy and carbon sources in urban ecosystem. Therefore, it is of great significance to evaluate the green campus, low-carbon campus and promote the construction of low-carbon campus effectively and reasonably through the measurement of carbon source and sink in campus ecosystem. Through the following aspects of the campus carbon sources, sinks were measured and analyzed: (1) the type of campus green space survey and carbon stock estimation, obtained the campus vegetation carbon pool first-hand information; (2) through a random questionnaire survey, The resource consumption and carbon footprint data of the whole school are obtained. (3) by collecting and analyzing the consumption of water, electricity, natural gas and other resources in the whole school in 20112013, the paper evaluates the common carbon footprint of the campus daily consumption. These are the basis of campus carbon source, sink measurement, and the necessary premise of campus carbon source, sink analysis and construction of low carbon campus. The main results are as follows: 1. A total of 91 species of Arbor trees in campus were investigated. The whole component power function isokinetic growth equation, which is suitable for the estimation of Arbor biomass in this study, is selected. There are 5 groups of isokinetic growth equations, 20 groups. The biomass of tree species and carbon storage in Anhui Agricultural University campus were 1988.93 mg and 994.46 mg 路2 respectively. A total of 13 species and 35 species of shrubs were investigated, and the volume of hedgerows on campus was measured. The whole plant power function of shrub biomass estimation was used to calculate the isokinetic growth equation. The biomass of shrub tree species and carbon storage were 690.09 mg and 289.77 mg respectively, and the density of shrub biomass of college students' apartment was 1.09 kg / m ~ (2.3) in Anhui Nong University campus, and the density of shrub biomass was 1.09 kg / m ~ (2.3). The average carbon dioxide emission per staff of Anhui Agricultural University is 1.56 mg / a, and the average carbon dioxide emission is 0.43 mg / a, and the average annual carbon dioxide emission is 777.00 mg / a; the average carbon dioxide emission per student is 0.47 mg / a, and the average carbon dioxide emission is 0.13 mg / a, and the average annual carbon emission is 2710.66 mg / a / a. The trees and shrubs in the campus vegetation of Anhui Agricultural University, as the main type of photosynthetic organisms, undertake the task of absorbing carbon dioxide and reducing the carbon emissions from the campus as a whole, and are the most important biomass carbon pool in the campus. Staff, students and the school public water, electricity consumption, constitute the campus's main carbon footprint. The campus of Anhui Agricultural University is a huge carbon source, and the carbon sink function of campus green vegetation still has great potential. Through increasing the management and optimizing the allocation of all kinds of vegetation on campus, the carbon sink function of campus green space will be further improved.
