摘要
基于生态足迹理论及其相关衍生模型,分析了江西省生态经济系统的运行态势,以期为区域可持续发展提供参考依据。研究表明,1980年以来江西省人口由3 270.2万人增长为4 339.1万人,同期生态人口容量却由2 162.63万人降低为1 512.94万人,因此生态超载人口由1 107.57万人增长为2 826.19万人,生态超载率由33.87%提高到65.13%,人口生态超载情况日益严重;人均生态足迹呈缓慢的波动式上升态势,由1.439 0 hm2增长到1.950 9 hm2,人均生态承载力却逐渐降低,由0.951 7 hm2降低为0.680 2 hm2,资源环境压力指数由1.26增大为2.05,生态安全等级由"稍不安全"降低为"很不安全"等级;生态经济耦合指数由0.51降低到0.43,可持续发展面临严峻挑战。
Based on the principle of ecological footprint and several extended models, the trends of PRED system in Jiangxi province were analyzed for the purpose of regional sustainable development. The results showed that, from 1980 to 2006, population increased from 3.27× 10^7 to 4.34 × 10^7, yet eco-capacity of population decreased from 2.16× 10^7 to 1.51 X 10z, so that eco-overload population increased from 1.11× 10^7 to 2.8× 10^7 , and the eco-overload population increased from 33.87% to 65.13% Ecological footprint increased from 1. 439 hm^2 per capita to 1. 950 9 hmz per capita, whereas, biocapacity declined from 0. 951 7 hm^2 per capita to 0. 680 2 hm^2 per capita. Therefore, the ecological tension index increased from 1.26 to 2.05, and the grade of ecological safety grade turned from ‘a little danger’ to ‘at risk ’ level. The ecological economic coordination index decreased from 0.51 to 0.43. The results revealed that the development of Jiangxi province is unsustainable.
