北京科技大学校园电能消耗生态足迹研究

生态足迹分析法是一种“强”可持续性进行衡量的手段。研究中以北京科技大学（以下简称北科大）为例，运用统计学中调查方法对2008年校园电能消耗进行调查，并应用生态学中生态足迹成分法模型对其进行分析，通过与北京及全国范围的对比，测度高校校园的可持续状况。结果表明：北科大2008年电能总消耗量为3829万千瓦时。生态足迹为7098．4hm^2，即需要7098．4bm^2的生态生产性土地支持该校的电能消耗，人均生态足迹为0．28hm^2，在忽略外部影响的情况下与北京及全国的电能生态足迹比较，学校的生态占用状况比较乐观。为促进高校节能减排的工作和建设生态和谐校园，并且有针对性地提出了一些切实可行的节能办法，供学校参考。

Research on Ecological Footprint for Electrical Energy Consumption in USTB

Ecological footprint analysis is an ＂efficient＂ mean to measure the sustainability. Taking University of Science and Technology Beijing （USTB）for an example, by using the survey in statistical methods to investigate consumption of electrical energy in the campus in 2008 ,and ecological footprint in ecology the composition of its model law for the analysis. Therefore, quantitative measurement of human impact on ecosystems, and with Beijing and nationwide contrast, measure the campus of University of sustainable situation. The results show that in 2008 the electric power consumption of USTB was 38. 29GW · h, the ecological footprint was about 7 098. 4 hm^2, it means that 7 098.4 hm^2 productive land of ecology is demanded for supporting electric power consumption of the school. The per capita of ecological footprint in this school is 0. 28 hm^2 each person, so the situation of this university is relatively optimistic compared with the situation of Beijing and China by ignoring external influences： In order to promote energy conservation and emissions reduction in colleges and universities and coustruct an ecological and harmonious campus, and put forward a number of practical energy - saving approaches for universities.
