| 摘 要： | 运用能值理论, 对传统生态足迹模型进行改进, 构建了改进模型. 对新疆维吾尔自治区1978—2007年生态足迹和生态承载力变化进行评价, 对模型进行了对比分析. 与传统生态足迹模型相比, 能值改进模型充分考虑了整个区域的生态足迹和承载力, 所以量化结果较大; 同时因其采用能值转换率等更稳定的指标, 在一定程度上克服了传统生态足迹模型的缺陷.

| Abstract: | We modify the ecological footprint (EF) methodology based on the theory of emergy analysis, and two modified models of ecological footprint accounting are formulated and applied to a case study in Xinjiang. The comparison between the conventional and modified EF models based on the different views of ecological production is outlined. The results of comparison show that the modified models are reasonable and feasible, although the modified and traditional EF models are quite different in some principles. |
