江西省1949-2004年生态足迹演变分析

生态足迹是定量研究区域可持续发展的一种重要方法。本文应用M ath is W ackernagel等提出的生态足迹评价方法对江西省1949-2004年生态足迹和生态承载力进行了计算和分析,以此来衡量江西省区域生态供给是否能满足开发和消费的需要,并定量化地研究了江西省经济发展对生态环境影响的程度。研究结果表明,从1949-2004年,江西省生态足迹逐步上升,生态承载力逐渐下降,目前人均生态足迹已超过人均生态承载力,生态赤字的出现表明当前江西省处在一种不可持续发展状态。同时探讨了江西省生态赤字产生的原因并提出了相应的解决方法。全文对维护江西生态安全、建设“绿色生态江西”、构建“和谐平安江西”具有重要现实意义和参考价值。

The Analysis of Jiangxi Province's Ecology Footprint Evolution Between 1949 -2004

The Ecological footprint is one of important methods to quantitatively investigate region sustainable development.With this method,The author computed and analyzed the ecological footprint and the biological capacity of Jiangxi Province between 1949-2004.And this method was applied to weigh the region ecology supplies function whether could satisfy the development and the expense need.The influence degree of the economy development on the ecological environment was studied quantitatively.The results showed that,from 1949 to 2004 year,the ecological footprint rose gradually and the biological capacity declined little by little.The per capital ecological footprint has surpassed the biological capacity.The ecological deficit appearances indicated current development is not sustainable in Jiangxi Province.At the same time the reason which the ecology deficit produced were discussed and the corresponding solutions were proposed.Its important practical significance is to maintain the Jiangxi ecology security,construct "Green Ecology Jiangxi",build "Harmonious Safe Jiangxi".
