运用能值理论,将河北省能值基础分为可更新环境资源、不可更新资源及产品、货币流和废物流四大部分。通过能值来源结构、经济子系统、生态子系统、社会子系统、可持续发展综合评价5个层面对该省2005~2014年生态经济系统发展趋势进行分析讨论,并进行可持续性评价。研究结果表明,河北省资源丰富,潜力巨大,但人口增长过快,发展较为粗放,外部资源利用不足,开发程度不够,且在开发过程中资源浪费较为严重,既给环境造成了污染,还导致资源大量消耗,影响生态经济环境的可持续性发展。针对以上问题,提出以下几点建议:(1)依靠科技进步,提高资源利用能力;(2)加大进口力度,转变进口结构,提高利用外部资源的能力;(3)加快产业布局调整,大力发展第三产业,提高经济竞争力。
Using the emergy theory, the basic of emergy in Hebei Province can be divided into renewable energy resources, non-renewable resources and products, currency flow and waste flow. The development trend of eco-economic system from 2005 to 2014 in the province was analyzed and discussed through five aspects of the source value structure, economic subsystem, ecological subsystem, social subsystem and sustainable development comprehensive evaluation, and the sustainable evaluation was conducted. The results show that Hebei Province has abundant resources and great potential. However, the population growth is too rapid, the development is rather extensive, the utilization of external resources is insufficient, the development level is not enough, and the waste of resources is more serious in the development process, causing pollution to the environment and causing A large number of resource consumption, affecting the sustainable development of ecological and economic environment. In view of the above problems, the following suggestions are put forward: (1) relying on scientific and technological progress and improving resource utilization capacity; (2) increasing import intensity, changing import structure and enhancing the utilization of external resources; (3) accelerating industrial restructuring and vigorously Develop the tertiary industry and improve economic competitiveness.
