摘　　要：生态足迹分析方法是一种衡量人地协调和生态可持续性评估的方法。文中运用生态足迹分析方法对宁夏地区1986-2005年生态足迹和生态承载力进行计算,揭示其人地协调度演变状态。结果表明:随着人口的不断增长以及消费水平的不断提高,该区域出现生态赤字并不断增大,生态系统处于过度开发之中,人地关系处于不协调发展状态,威胁着区域生态经济系统的稳定性和可持续发展。Ecological Footprint is an important indicator to evaluate the Human-environment Coordination and the sustainable use of ecosystem.We calculated the ecological footprint and the ecological carrying capacity of Ningxia between 1986 to 2005 based on the ecological footprint model to show the state of human-environment coordination fluctuations.The results showed that ecological deficits occurred and then continued to increase,which demonstrated that great human-environment conflicts was existed,and Ningxia was in a state of unsustainable development,which posed a grave threat to the stability and sustainable development of the regional ecological economic system.
