通过构建包括能值流、能值来源指数、社会子系统评价指数、经济子系统评价指数、自然子系统评价指数和综合指数的能值分析评价体系，对辽宁省2000 - 2010年生态经济系统的发展与可持续性进行了评价。结果表明，2000 - 2010年，黑龙江省可持续发展的能值总量从3440.12 × 10（20）sej增加到7636.33 × 10（20）sej，其中2010年不可更新能值占能值总量的比重最大，为68.6%人均能值由8.32 × 10（15）sej增加到17.96 × 10（15）sej。系统能值自给率总体较高，但从2000年的91.1%下降到2010年的79.9%。能值负荷率由3.22提高到7.80，能值可持续指数由3.47下降到0.64，可持续发展指数由6.73下降到1.56。结果表明，辽宁省生态经济系统呈现出不可持续的发展趋势。2010年辽宁的发展水平仅相当于日本和美国在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 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 x 10(20) sej to 7636.33 x 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 x 10(15) sej to 17.96 x 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 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.
