摘要
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。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1.74×106hm2,海洋生态系统总能值-生态承载力为1.60×107hm2,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。
An energy-based ecological footprint model was set up to monitor the sustainable development status of a specific marine system. This model used unit energy value and energy density to convert the consumption into ecological productive areas. It can reflect the utilization degree of resources in the regional development. Then, the quantitative analysis of sustainable development was carried out by comparing the sizes of the areas. We defined the concept of energy-based marine ecological footprint and built energy-based marine ecological footprint model. Then we applied this model to the marine ecological system of Shandong Province to evaluate its sustainable development status. The results showed that the ecological footprint of energy-based marine ecological system in Shandong Province was 1.74 ×10^6hm^2in2010, and the energy-based ecological carrying capacity of this area was 1.60 ×10^7hm^2per capita. Thus, the marine ecological system of Shandong Province has strong sustainability.
