| 摘 要： | 能值生态足迹法（EEF）是一种基于生态足迹的对区域生态系统的可持续发展状况予以评估的能值分析方法。以陕川渝三省（市）为研究对象，利用人均能值生态承载力和人均能值生态足迹以及万元GDP对2007年三地生态经济系统可持续状况进行了分析，并就陕川渝区域之间合作的优先性从可持续发展的角度予以客观评价。结果表明：2007年陕川渝三地的能值生态赤字分别为3.604hm2、1.467hm2、1.268hm2，万元GDP生态足迹分别为3.162hm2、2.31hm2、1.632hm2；三地均处于不可持续发展状况，且陕西的情况最为严重，资源利用效率最低；陕川渝三地的发展各自面临一定的资源短缺问题，依靠进口或者过度开发来为维持社会经济的高速发展，势必会引发一系列的生态问题，在新的时期原有的以环境为代价发展经济的传统发展模式遇到了挑战，只有因地适宜地对这种模式进行优化调整，才会使陕川渝各地的发展持续化，从而推动西部发展。

| Abstract: | Emergy ecological footprint method (EEF) is based on the ecological footprint of the regional ecosystem to assess the sustainable development of the emergy analysis method.Taking the three provinces of Shaanxi, Sichuan and Chongqing as the research objects, the three eco-economic system sustainable situation was analyzed by using the per capita emergy ecological carrying capacity and ecological footprint as well as EEF per 10000 yuan GDP in 2007, and an objective evaluation to the region's priority of co-operation was given between Shaanxi and Sichuan-Chongqing from the perspective of sustainable development. The results show that: the ecological deficit of Shaanxi Sichuan, Chongqing in 2007 is 3.604hm2, 1.467hm2, 1.268hm2 respectively, million to GDP is 3.162hm2, 2.31hm2, 1.632hm2 respectively. These three regions are all in non-sustainable development situation, and the situation is the most serious for Shaanxi, which is in the lowest resources efficiency use ; The development of Shaanxi , Sichuan and Chongqing will face a certain resources shortage, they have to rely on imports, or over-development to maintain the rapid economic development which will inevitably lead to a series of ecological problems and cause the challenge to the original model of development in these three places during the new period. Only through some appropriate changes and adjustments , can the development of the local be sustainable, thus promoting the western's development. |
