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3440.12×1020sej增长到7636.33×1020sej,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8.32×1015sej增长到17.96×1015sej;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.By constructing an evaluation system based on emergy analysis which included emergy flow, source of emergy index, social subsystem evaluation index, economic subsystem evaluation in- dex, 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 × 10^20 sej to 7636.33×10^20 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 8.32×10^15 sej to 17.96×10^15 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 sus- tainable index dropped from 3.47 to 0.64, and the emergy index for sustainable development de- creased 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.
