摘  要:【目的】分析1949-2008年吉林省乾安县能值生态足迹动态,评价乾安县可持续发展演变情况。【方法】运用能值生态足迹法,对乾安县1949-2008年的能值生态足迹进行研究,分析该区域人均能值生态足迹、人均能值生态承载力和人均能值生态盈亏的动态变化。【结果】1949-2008年,乾安县人均能值生态足迹呈上升趋势,平均每年上升19.3%,而人均能值生态承载力呈下降趋势,平均每年下降10.2%。1949-1978年,乾安县人均能值处于生态盈余状态,但呈下降趋势,人均能值生态盈余从1949年的5.784 2hm2下降至1978年的0.253 9hm2,平均每年下降18.4%;1983-2008年呈现生态赤字状态,人均能值生态赤字从1983年的3.334 2hm2增加至2008年的11.899 2hm2,平均每年增加32.9%。【结论】自1978年之后,乾安县经济快速发展是以过度开发自然资源为代价的;只有因地制宜地对该区域人口、社会经济、工农业和自然环境状况进行优化整合,才能更好地促进其可持续发展建设。【Objective】 This paper is intended to analyse the ecological footprint of Qian'an county from 1949 to 2008 and to evaluate the evolution of sustainable development.【Method】 The energetic ecological footprint theory(EEF) was applied to analyse the ecological footprint of Qian'an county from 1949 to 2008.Based on the EEF method,this paper focused on analyzing the dynamic trends of per capita energetic ecological footprint,energetic ecological carrying capacity and energetic ecological surplus and deficit within sixty years.【Result】 Results show that from 1949 to 2008,the per capita ecological footprint of Qian'an county continued to rise at the average annual rate of 19.3%,and the per capita ecological carrying capacity decreased by 10.2% year by year.This region was in ecological surplus from 1949 to 1978,and the per capita ecological carrying capacity decreased from 5.784 2 hm2 per capita in 1949 to 0.253 9 hm2 per capita in 1978,decreased by 18.4% every year.While from 1983 to 2008,the ecological deficit was increased year by year.The per capita ecological deficit increased rapidly from 3.334 2 hm2 in 1983 to 11.899 2 hm2 in 2008,32.9% in annual rise rate.【Conclusion】 Results reveal that,since the reform and opening up in 1978,the rapid economic development of Qian'an county has been based on the cost of over-exploitation of natural resources,and sustainable development would face an austere challenge.Only by optimizing the integration of the regional population,socio-economic,industrial,agricultural,and natural environmental conditions according to the local conditions,the sustainable development will be better promoted.
