摘　　要：通过查阅长沙市统计年鉴,搜集相关数据资料,应用生态足迹的方法对城市化水平进行定量计算,把生态足迹中涉及的可耕地、林地、河流水域、草地、建设用地、能源提供地六大类生物生产性土地概括为生物资源消费和能源消费两部分,根据数据资料的获取和实际情况,选取其中22个指标,通过设置均衡因子,进行计算汇总得出长沙市2008—2012年的人均生态足迹;同时将城市化水平分为人口城市化、经济城市化、生活方式城市化、地域景观城市化四个测度,结合长沙市实际,选取其中具有代表性的17个指标,运用城市化测度模型计算得出2008—2012年长沙市的城市化水平,再利用线性回归分析方法对生态足迹与城市化水平进行统计,综合分析得出城市化发展过程中的生态环境动态变化情况以及城市化发展过程中存在的问题,对未来城市化的发展提出合理、有效的建议,以期指导长沙市城市的可持续发展,并为规划决策提供科学依据。Based on Changsha Statistical Yearbook,collect relevant data,apply ecological footprint approach to quantitatively calculate the level of urbanization. At the same time,the ecological footprint of arable land,forest land,river water,grassland,construction land,energy supply to the six major categories of bio productive land summarized as two parts of biological resources consumption and energy consumption,and according to the data acquisition and the actual situation,select the 22 indicators,by setting the balance factor,to calculate and summarize the per capita ecological footprint of Changsha City from 2008 to 2012. At the same time the level of urbanization is divided into four measures,the population urbanization,economy urbanization,lifestyle urbanization,geographical landscape urbanization. Combined with the actual Changsha,selecting 17 representative indicators,using the model of urbanization measurement calculated urbanization level of Changsha City from 2008 to 2012,then using linear regression analyzed the ecological footprint and urbanization level,comprehensive analyzed the dynamic changes in the ecological environment as well as the problems in the process of urbanization. Reasonable and effective recommendations for the future development of urbanization were put forward to guide the sustainable development of Changsha,and provide scientific basis for planning decisions.
