摘 要: 研究目的:将生态足迹理论运用到建设用地的节约集约利用评价之中,完善节约集约利用评价指标体系。研究方法:时间序列法、文献资料法、计量模型法、逻辑分析法。研究结果:2002~2007年间,重庆市非农人口人均建设用地生态足迹增加了0.636854hm2,二三产业万元GDP生态足迹下降了0.032070hm2,单位面积建设用地生态足迹增加了34.379060hm2。研究结论:(1)重庆市二三产业的发展对生态环境的压力有减小的趋势,能源资源的利用效率得到提高。(2)二三产业总生态足迹的增加速度远大于建设用地总面积的增加速度,也就是建设用地的增加引起了生态足迹(生态需求)更大的增加。(3)建设用地生态足迹的增加主要是由于非农人口消耗更多的能源和资源所导致。 The purpose of the study:apply the ecological footprint theory in the evaluation of construction land intensive use and improve the evaluation index system.Method of time series analysis,literature analysis,measurement model and logical reasoning are employed.The result shows:1) ecological footprint of per non-agricultural population in construction land increased by 0.636854 hectares;2) ecological footprint of 10 thousand Yuan GDP in construction land dropped by 0.032070 hectares;3) ecological footprint of per unit area of construction land increased 34.379060 hectares.The conclusions as following:1) the development of Chongqing has reduced the pressure on the ecological environment,the utilization efficiency of energy resources has been enhanced;2) the growth speed of secondary and tertiary industries in the ecological footprint is much faster than the construction land;3) ecological footprint of construction land was mainly due to increased non-agricultural population consume more energy and resources.
