【摘要】：随着可持续消费理论的深入研究,城镇家庭作为终端消费部门,成为可持续消费的主要研究对象,因此针对城镇家庭开展"细胞尺度"的环境影响评价非常重要且必要。本文基于物质流分析方法,建立了中国城镇家庭物质流核算框架,为物质流分析在家庭层面的研究提供了新思路。以2015年平均一个城镇家庭为研究对象,计算了城镇家庭的平均物质资源交换情况。结果显示:2015年平均一个城镇家庭的直接物质投入为86420.92kg,物质输出量为83457.98kg,物质存量净增加为2 374.08kg;从消费类别上看,居住、食品和交通是主要的物质投入来源。针对中国城镇家庭消费的现状,本文提出对应政策建议,倡导居民改变不可持续的消费理念,向可持续的家庭消费模式转变。
[Abstract]:With the in-depth study of sustainable consumption theory, urban households, as the end consumption sector, become the main research object of sustainable consumption. Therefore, it is very important and necessary to carry out "cell-scale" environmental impact assessment for urban households. Based on the method of material flow analysis, this paper sets up a framework of material flow accounting for urban households in China, which provides a new idea for the study of material flow analysis at the family level. Taking the average urban household as the research object in 2015, the average material resource exchange of the urban household was calculated. The results showed that in 2015, the direct material input of an average urban household was 86420.92 kg, the material output was 83457.98 kg, and the net material stock increased to 2 374.08 kg. In terms of consumption category, housing, food and transportation were the main sources of material input. In view of the present situation of household consumption in cities and towns in China, this paper puts forward corresponding policy suggestions and advocates that residents should change their unsustainable consumption concept and change to sustainable household consumption patterns.
