基于能值生态足迹法的山东省可持续发展分析

传统生态足迹方法自提出以来已广泛应用到可持续发展的研究中，但其改进方法能值生态足迹法在可持续发展中的运用还很少。简要介绍了传统生态足迹模型和基于能值分析理论的生态足迹模型，并运用这两种方法对山东省2002～2006年的生态足迹进行了计算与对比分析。在此基础上测算了衡量区域可持续发展程度的两个指标：生态足迹多样性指数和生态协调系数，计算结果均呈下降趋势，表明山东省对各种土地的需求越来越不平衡，需求与供给之间的差距越来越大，山东省处于不可持续发展状态。通过对比研究，与传统生态足迹模型相比，改进生态足迹模型的计算结果更能真实反映生态经济系统的环境状况。

Analysis of Sustainable Development in Shandong Province Based on Emergetic Ecological Footprint Method

Conventional ecological footprint model has been widely used in the study of sustainable development,but its modified model based on emergy analysis is rarely used.The conventional ecological footprint model and emergetic ecological footprint model were introduced.Based on these two models,the ecological footprints of Shandong province from 2002 to 2006 were calculated and analyzed.The ecological footprint diversity index H and the corresponding types of ecological DS were also calculated.They were the indics to measure regional sustainability.The declining results of H and DS indicated that the demand of six main categories of biological productive areas was becoming more and more unbalanced and the ecological deficit is becoming larger.The research indicated that the development of Shandong was not sustainable.Compared with the conventional ecological footprint,the calculation results of emergetic ecological footprint model gave a more realistic reflection of the environmental situations of the eco-economic systems.
