兰州大学(盘旋路校区)2003年生态足迹调查分析

Investigation and Analysis of Ecological Footprint in Lanzhou University in 2003

人均消费产品的数量是计算区域人均生态足迹关键和基础的一步。通过实地问卷调查,运用自下而上法收集资料,计算小尺度生态足迹。兰州大学(盘旋路校区)2003年的生态足迹计算结果为:人均生态足迹0 892hm2,男、女生的人均生态足迹分别为0 976hm2和0 788hm2。这些数据与全国或者西部的人均生态足迹相比明显偏低,但总生态足迹为4119 3hm2,是校园面积的73 7倍。因此,应合理利用自然资源,减少学生的生态足迹,真正做到可持续发展。

The quantity of per capita consumption products is the pivotal and basal step of calculating the per capita ecological footprint in regional scale.Through field questionnaire investigation,using the way of collecting data from bottom to top,the authors calculated the ecological footprint of Lanzhou University(Panxuanlu campus) in 2003.The results show that the per capita ecological footprint in Lanzhou University(Panxuanlu campus) is 0.892 hm^2 in 2003.The per capita ecological footprints of male student and female student are respectively 0.976 hm^2 and 0.788 hm^2.Analyzing these data by degree,the per capita ecological footprint of undergraduates and masters are 0.875 hm^2 and 0.845 hm^2 apart and the per capita ecological footprint of doctors that is 1.097 hm^2 is the most.Though these data are obviously lower than the per capita ecological footprint in China or in western area in China,the total ecological footprint of Lanzhou University(Panxuanlu campus) is 4 119.3 hm^2 in 2003,which is 73.7 times of the area of Lanzhou University(Panxuanlu campus).Hence,it is still necessary to advocate the model of sustainable consumption by reducing the use of on-off products and to improve the use efficiency of energy in order to reduce ecological footprint and realize the sustainable development indeed.
