【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 local process emission (DPO) are two important indicators in the material flow analysis framework. Based on the EW-MFAA Economy-Wide Material Flow Analysis (EW-MFA-Economy-Wide Material Flow Analysis), the per capita DMI and DPO indices of 30 provinces (cities) of China in 1992 and 2014 are calculated. The results show that, compared with 1992 and 2014, the pressure of resources and environment in each province shows an increasing trend, especially in the middle reaches of the Yellow River and the provinces in northwest China. The gap of resource and environment pressure in each province is large, and the distribution pattern is high in northwest and low in southeast. In Inner Mongolia, Shanxi, Qinghai, Ningxia and other provinces in northwest China and the middle reaches of the Yellow River, the pressure of resources and environment is the greatest. Beijing, Shanghai, Tianjin, Guangdong and other eastern provinces have the least pressure on resources and environment, which is mainly caused by the large gap between resource endowment and industrial structure of each province. However, the key to change China's resources and environment pressure and lack of sustainable development potential lies in the northwest and middle reaches of the Yellow River, as well as the northern coastal and eastern coastal economic zones.
