基于NFA计算方法的厦门市生态足迹分析

Analysis of ecological footprint of Xiamen based on calculation methodology of NFA

运用国家生态足迹账户(NFA)计算方法(2010版),计算并分析2000～2009年厦门市的生态足迹和生态承载力,旨在展示国外生态足迹计算方法研究最新进展,更准确地揭示近年厦门市生态足迹和生态承载力状况。结果表明:2000～2009年厦门市人均生态足迹由1.686 9 gha快速增长至3.245 2 gha;人均生态承载力由0.317 2 gha持续下降为0.268 5 gha;生态赤字持续快速扩大,支撑经济发展由需要5.32个厦门变为需要12.09个厦门的生态承载力;碳吸收地在生态足迹结构中始终占据第一位且呈快速扩大趋势,是厦门市生态赤字的主导因素;生态效率呈持续增长趋势,但目前厦门市生态效率还远低于主要发达国家。

Calculation methodology of the National Footprint Accounts(NFA),2010 Edition,was adopted to calculate and analyze the ecological footprint and biological capacity of Xiamen over 2000-2009.We presented the latest improvements in the calculation methodology for ecological footprint and manifested more accurately the evolution of ecological footprint and biological capacity in Xiamen during the recent years.The results indicated that during the period from 2000 to 2009 in Xiamen,per capita footprint grew rapidly from 1.686 9 gha to 3.245 2 gha;per capita biocapacity kept on declining from 0.317 2 gha to 0.268 5 gha;ecological overshoot expanded quickly,requiring 12.09 times instead of 5.32 times of Xiamen’s biocapacity to support the city’s economic development.As carbon footprint was always the largest contributor to the total footprint among the footprint components and its share rose magnificently,it was a dominant factor resulting in ecological deficit.Although eco-efficiency there increases continuously based on eco-footprint and GDP,it is now far lower than that in the other main developed countries.
