title: [Ecological footprint in building green university].
abstract: Ecological footprint is one of the best indexes to evaluate the level of green university. The approaches of ecological footprint are made up of compound approach and component approach. This paper introduces the basic principle and algorithm of the componential approach of ecological footprint, taking Northeastern University as an example and using this approach in the research of campus. Result show that the ecological footprint of Northeastern University 2003 was 24 787hm2, needing the productive land of ecology about 25 000hm2 support all kinds of consumption of the school and absorb the offal. The ecological efficiency of the school was 0.94cap/hm2. In the ecological footprints, the energy's footprints is the largest, it accounted for more than 2/3 of the total footprints, the next are food consumption and solid rubbish.
