摘要
应用调整的生态足迹方法,对辽宁省1996—2003年的生态足迹进行了计算与分析,从纵向比较并分析了辽宁省近年来在发展过程中所受到的环境压力.结果表明:辽宁省1996—2003年生态超载指数都大于2,有的年份甚至接近于3,这说明辽宁省当前的生物资源的生产和能源的消费的能力远超过其生态承载能力,即生态资源处于高强度利用状态,生态环境有潜在恶化的趋势.辽宁省1996—2003年生态效率稳步上升,从1996年的2 569元.hm-2上升到2003年的4 101元.hm-2,提高了0.6倍,年平均增长率为7.5%.但与其它工业化国家相比还有很大的差距,这说明辽宁省在提高生态效率方面还有更大的潜力.
As the society is developing forward constantly, the mankind is strengthening exploitation and utilization of natural resources constantly. Success of industrial revolution caused the human being＇s ability of exploiting natural resources get all --time improved, and sustained the high--speed development of economic, but at the same time, forest, soil, water, air and biologic diversity were accelerated deterioration. Environmental deterioration and ecological degeneration also affected the sustainable development of social economy. There are some indexes to appraise the sustainable development; this paper chooses the index of ecological footprint, which is very popularity in international academia as an index of sustainable development. Since it published in 1992, because of its notional visualization, easily to understand and calculation, the ecological footprint was attended broadly by a lot of researchers of academia and many governments. Liaoning Province was the largest heavy industry bases since the new China come into existence; it did great contribution for Chinese economy. The decision-making of rejuvenating the northeast old industrial base provide a new chance for the social economy of Liaoning Province, but how to rebuild and rejuvenating the northeast old industrial bases and implementing the sustainable development of Liaoning Province economy and ecological harmony, not only is a strategic problem, but also is one aim of rejuvenating the northeast old industrial bases. This paper uses the adjustive ecological footprint to research the sustainable development of Liaoning Province. The results show that the EOI （Ecological Overshoot Index）of Liaoning Province from 1996 to 2003 were all exceed 2, and is very close to 3 in some year, which means the ecological footprint of Liaoning Province greatly exceeds the ecological capacity of Liaoning province, and the ecological environment would be deteriorated in the future. The ecological efficiency had an unfaltering raise from 1996 to 2003, and the ecological efficiency increased from 2569 Yuan· hm^-2 in 1996 to 4101 Yuan · hm^-2 in 2003, with an average ratio of 7. 5%. However, there is still a ;large gap as compared with industrialized countries.
