基于EMA的福建省生态足迹分析

生态足迹是衡量一个国家或地区可持续发展程度的一种方法,定量反映人类活动对生态环境的影响和破坏程度。以福建省2009年统计数据为基础,运用能值分析理论（EMA）,改进了原有生态足迹模型的计算方法,对福建省2009年的生态足迹进行了研究。研究结果表明：福建省本地潜在人均生态承载力为0.890 03 ghm2/人,本地产品产...

EMA-based Ecological Footprint Analysis in Fujian Province

Ecological footprint is a method to test sustainable development level of a country or region, reflecting quantitatively interference and disruption of human activities on ecological environment. Based on the statistical data of Fujian Province in 2009, this article improves the calculating method of previous ecological footprint model by using energy analysis approach （EMA） and studies the ecological footprint of Fujian in 2009. The results show that： the potential ecological capacity of Fujian is 0. 89003ghm2 per capita,the output capacity of local products of Fujian is 2. 53669ghm2 per capita and the ecological footprint of Fujian is 1. 57034ghm2 per capita. Thus the ecological deficit of Fujian is 0. 68031ghm2 per capita. Ecological energy loading ratio reaches 176%, which indicates that the eco-economic system of Fujian are in an unsustainable development state.
