摘要
采用生态足迹成分法,分析了沈阳市皇姑区5所中小学校学生家庭消费对自然环境的影响。结果表明:食物是中小学生家庭生态足迹的主要消费项,占生态足迹总量的71%;从生态占用的土地类型构成看,耕地项最大,占总足迹的40%,是中小学校学生家庭消费所占用的主要土地类型;家庭收入高低与生态足迹大小并不呈正比例关系,收入高或低都可能产生较高的生态足迹。本研究结果有助于中小学生及其父母了解自己的消费对周围环境的影响,有利于提高中小学生的环境保护保意识。
The componential method of ecological footprint calculation was applied to analyze the effect of the student household＇ s consumption from five primary and middle schools on the environment in Huanggu District of Shenyang City. The results showed that the food was the biggest component of ecological footprint in primary and middle school students＇ households, accounting for 71% of the total personal ecological footprint. According to the types of land occupied by eco- logical footprint, arable land was the largest item, accounting for 40% of the total footprint. The income level of households was not directly related with the ecological footprint, for example, the low or high incomes might generate high ecological footprint. The results would be helpful for the primary and middle school students and their parents to understand the relation of their consumption and the surrounding environment and to enhance the students＇ consciousness of environmental protection.
