从生产角度对大连市能值生态足迹分析

以Zhao等提出得“能值足迹”方法和顾晓薇等提出的“本国足迹”理论为基础，从生产角度计算分析了辽宁省大连市2002年的生态系统的可持续发展情况，并对比本地能值生态足迹、能值足迹和传统生态足迹的计算结果，包括生态足迹、生态承载力、生态盈余、生态足迹强度指数和生态超载指数。各方法均得到同样结论：大连市存在生态赤字，分别为2．24，5．13和18．71。本地生产导致的生态超载指数最大，为62．91。

Analysis of Emergetic Ecological Footprint of Dalian City from the Perspective of Production

On the basis of the methods of emergetic ecological footprint （EEF） which was advanced by Zhao et al. and Local Ecological Footprint by Gu et al. , this paper uses yield of regional biological resources to substitut biological consumptions. We compared our calculation with that of original ecological footprint and emergetic ecological footprint of a regional case. We select Dalian city of Liaoning province in northeast China as an example for the application of our study, and calculated ecological footprint, ecological carrying capacity, ecological deficit, ecological footprint intensity index and ecological overshoot index. In this case the same conclusions were drawn from all methods that Dalian city runs an ecological deficit： 2.24,5.13 and 18.71 respectively. The largest EOI which produced by local emergetic ecological footprint （LEEF） was 62.91.
