能值-生态足迹模型是基于能值理论基础,结合生态足迹模型,运用区域能值密度将各项消费项目转换为可以直接相加的生物生产性面积,并以此来反映区域发展对区域环境资源的利用程度,衡量和评价区域海洋经济的可持续发展状况。本研究将能值-生态足迹模型应用到区域海洋生态系统中,对海洋能值-生态足迹概念进行了界定,构建了海洋能值-生态足迹模型,并以山东省海洋生态系统为例进行了实证研究。结果表明,2010年山东省海洋生态系统总能值-生态足迹为1.74×106hm~2,海洋生态系统总能值-生态承载力为1.60×107hm~2,处于生态盈余状态,反映出山东海洋经济具有较强的可持续性。
Emergy - Ecological Footprint model is based on the theory of emergy, combined with the ecological footprint model, the use of regional energy density of the consumer projects can be converted directly into bio-productive area, and in order to reflect the regional development of the regional environment Resource utilization, measure and evaluate the sustainable development of the marine economy in the region. In this study, the emergy-ecological footprint model was applied to the regional marine ecosystem. The concept of marine energy-ecological footprint was defined, and the model of marine energy-ecological footprint was established. Taking the marine ecosystem in Shandong Province as an example Empirical Research. The results show that the total emergy value of the marine ecosystem in Shandong Province in 2010 is 1.74 × 106hm 2 and the total emergy value of the marine ecosystem is 1.60 × 107hm 2, which is in the state of ecological surplus, which reflects that the marine economy of Shandong With strong sustainability.
