摘要：

基于能值分析构建了包括能值流量、能值来源指标、社会亚系统评价指标、经济亚系统评价指标、自然亚系统评价指标和综合指数等的辽宁省生态经济系统评价体系，全面评估了2000—2010年辽宁省生态经济系统的发展趋势以及可持续性.结果表明： 2000—2010年，辽宁省总能值用量从3440.12×10²⁰ sej增长到7636.33×10²⁰ sej，其中，2010年不可更新资源能值所占比重（68.6%）最大；人均能值从8.32×10¹⁵ sej增长到17.96×10¹⁵ sej；能值自给率虽然较高，却从2000年的91.1%下降到2010年的79.9%；环境负荷率从3.22提升到7.80；可持续发展指数由3.47降低到0.64；系统可持续发展性能由6.73降低到1.56.表明辽宁省生态经济系统呈现出不可持续发展的态势.2010年的辽宁省生态经济水平仅达到美国和日本20世纪80年代的水平.

Abstract: By constructing an evaluation system based on emergy analysis which included emergy flow, source of emergy index, social subsystem evaluation index, economic subsystem evaluation index, natural subsystem evaluation index and composite index, the development and sustainability of the ecoeconomic system of Liaoning Province between 2000 and 2010 were evaluated. The result showed that from 2000 to 2010, the total used emergy increased from 3440.12×10²⁰ sej to 7636.33×10²⁰ sej, among which the proportion of the nonrenewable emergy in 2010 occupied the most in the total by 68.6%, and the emergy per capita increased from 8.32×10¹⁵ sej to 17.96×10¹⁵ sej. The emergy selfsupport ratio in the system was generally higher, while it dropped from 91.1% in 2000 to 79.9% in 2010. The emergy loading ratio increased from 3.22 to 7.80, the emergy sustainable index dropped from 3.47 to 0.64, and the emergy index for sustainable development decreased from 6.73 to 1.56. It suggested the ecoeconomic system of Liaoning Province presented an unsustainable development trend. The development level of Liaoning in 2010 merely equaled to the level of Japan and America in the 1980s.
