比较生态足迹指数、环境可持续性指数（ESI）、自然资本指数（NCI）等作为衡量生态经济系统可持续性指标的不足后，选择能值分析及其指标作为定量评价区域可持续发展状态的方法和指标。通过对甘肃1994—2004年的净能值产出率（NEYR）、能值投入率（RIR）、环境负载率（ELR）和可持续发展能值指数（ESI）等7项指标的计算及趋势分析，并与其他国家和地区比较得出：甘肃经济还处于较低水平，开放程度依然有限，能值消费和利用结构也是低层次的，近年工业化步伐虽然加快，但要实现甘肃的可持续发展，仍需重视经济发展的作用，通过进口低能值、高能量的产品而输出高能值的产品和服务，达到自组织最优化状态（能源利用高效率）和系统对外最大功（强势竞争力）；甘肃可持续发展指数（ESI）的波动下降与甘肃经济的快速增长不无关系。重视经济增长和控制其对环境系统的压力，保持可持续发展指数的平缓降低尤为重要。

Sustainability assessment indices as a hot topic in the Sustainable Development Research. Emergy analysis methods and relevant assessment indices have primary advantages at sustainability evaluation process, it can calculate the whole eco-economic system's each kind of contents into a single index as Solar Emergy to analysis its' sustainable conditions. In this paper we choose some Emergy indices such as Net Emergy Yield Ratio(NEYR), Emergy Investment Ratio(EIR), Environmental Loading Radio(ELR), Emergy Dollar Ratio(EDR), Emergy Density(ED), Fraction of Emergy Used form Electricity(FEE) and Emergy-Based Sustainability Index(ESI) to assess the Eco-economics System sustainable development situation of Gansu province. By the change tendency of Gansu'NEYR , ELR, EIR and ESI indices from 1994 to 2004 and the comparisons between other countries and regions, it could be concluded that: the change tendency of NEYR and EIR from 1994 to 2004 reflects the economic development stage of Gansu is at lower level in China, Emergy consumes and yields structure are also at the similarly lower level, compared with other countries and regions. The emergy consumption and utilization structure also at a lower level. To realize the objectives of the sustainable development, that is to say the maximum of the whole system yields power as well as the minimum of environment negative effects; the system should adjust its economic structure to optimize the self-organized situation. The change tendency of ESI has a close relation with the economic growth of Gansu. To keep the sustainable development index steady decrease, the government of Gansu Province should takes a peer efforts to focus on economic growth and control eco-system's press on environment.
