摘要:

直接物质投入(DMI)和本地过程排放(DPO)是物质流分析框架中两个重要指标,可以反映一个经济系统的资源环境压力。本文基于经济系统物质流分析方法(EW-MFA,Economy-Wide Material Flow Analysis)核算中国30个省(市)1992年和2014年的人均DMI和人均DPO指标,分析中国社会经济系统资源环境压力的时空变化。结果显示:对比1992年和2014年,各省份的资源环境压力均呈增大趋势,其中黄河中游和西北各省份的资源环境压力增长最快;各省份的资源环境压力差距较大,总体呈现西北高、东南低的分布格局,其中内蒙古、山西、青海、宁夏等西北和黄河中游省份的资源环境压力最大,北京、上海、天津、广东等东部省份的资源环境压力最小,这一分布情况主要由各省份资源禀赋和产业结构差距较大导致;中国各经济区均面临不同程度的资源环境问题,但改变中国资源环境压力大、可持续发展潜力不足的关键在西北和黄河中游以及北部沿海和东部沿海经济区。

Abstract:

Direct material input(DMI)and domestic processed output(DPO)are the two main indicators in the economy-wide material flow analysis(EW-MFA)reflecting resource and environmental pressure in an economic system. To analyze spatial and temporal changes in China’s resource and environmental pressure,we calculated DMI per capita input and DPO per capita for 30 provinces in 1992 and 2014 based on EW-MFA. Results of this study show that resource and environmental pressures in these provinces have increased during the past 23 years. The northwest and middle reaches of Yellow River regions have the highest growth rate in resource and environmental pressure. These provinces have very large differences in resource and environmental pressure,which is obviously high in the northwest and low in the southeast. The northwest and middle reaches of Yellow River regions,such as Inner Mongolia,Shanxi,Qinghai and Ningxia have the highest resource and environmental pressure. Eastern areas such as Beijing,Shanghai,Tianjin and Guangdong,have the lowest resource and environmental pressure. This distribution is caused by large gaps in the resource endowment and industrial structure among provinces. Different regions in China have different resource and environmental problems. However,the northwest and middle reaches of Yellow River regions,and the northern and eastern coastal regions need to be improved to reduce high resource and environmental pressure and to realize sustainable development across China.
