摘要:生态足迹理论的出现是为了衡量资源可持续利用状态,但后续的研究中人们将生态足
迹与所提供的生物承载力进行比较,考察人类对生态系统的依赖性和生态系统的承受能力,
以了解区域人口对自然资本的利用程度和资源的短缺程度,并用于度量一定区域人类生存的
安全程度。本文对生态足迹产生的背景、相关概念、生态足迹模型以及基于生态足迹理论的
生态承载力模型进行综述,分析该理论在生态安全评价中的应用前景,可为生态安全评价提
供有效的手段。

Abstract: The emergence of the ecological footprint theory is to measure the state of resources
sustainable utilization. Still, some pared the ecological footprint and biocapacity
in subsequent studies, and examined the dependence of the human on ecosystem and the
affordability of ecosystem. In consequence, the degree of utilization of natural capital by the
regional population and the degree of resource shortages can be understood. Furthermore, the
results can used to measure the degree of security of human existence in a certain area. This article
summarized the background of ecological footprint, the related concepts, ecological footprint
models as well as the ecological footprint theo
