摘　　要：基于能值理论(emergy theory),在分析港口资源消费和污染等生态足迹的基础上,考虑船舶在港作业期间对生态环境的影响,提出基于EEF模型(emergy-ecological footprint)的港口生态评价方法,将港口生态承载力分析计算扩展为自然资源生态承载力和社会经济虚拟承载力两类账户。以北方某港区为例计算了2009~2014年的生态足迹与生态承载力,结果表明港区历年生态承载力指数均大于1,处于生态不可持续状态,能源足迹与污染足迹是港口生态足迹的主要来源。港口经济虚拟生态承载力账户对港区生态承载力的贡献高于自然资源生态承载力账户,可有效控制生态赤字规模。By analyzing ecological footprint of resource consumed by port and waste, and considering the effect on environment of vessels, the EEF model （emergy-ecological footprint） for ecological evaluation of sea port has been built up based on emergy theory. Port ecological capacity was made up of the accounts of natural resources and the virtual accounts of port economic development. The ecological footprint and carrying capacity of a Northern China port from 2009 to 2014 was calculated. The ecological capacity index remained above 1 each year, which led to unsus;ainable port ecology. The energy ecological footprint and the pollution ecological footprint was main source of ecological footprint. The virtual accounts of port economic development contribute more for port ecological capacity, which avoided the growth of ecological deficit effectively.
