摘　　要：在全球公顷、国家公顷和省公顷的模型基础上,建立了市公顷生态足迹计算模型,阐明了均衡因子与产量因子的相关概念与计算方法。以某市为例,计算了2007年其均衡因子和其市域范围内某县的产量因子,结果与全球公顷和国家公顷模型下的数值存在较大差异,但这一差异是合理的。研究表明,市公顷方法更适合市级以下区域生态足迹的核算和比较,计算所得的均衡因子和产量因子更能反映小区域的实际,相对误差较小。Based on the models of global hectare,national hectare and provincial hectare,the ecological footprint model of city hectare was established,relevant connotations and calculation methods of equivalence factor and yield factor were expounded. Taking a city as the case,the equivalence factor of the city and the yield factor of a county in the city in 2007 were calculated. The results were very different from the values with global hectare model and national hectare model,but the difference was rational. The research showed that city hectare method was more suitable for the calculation and comparison of regional ecological footprint under city level. The results could reflect the real conditions of the regions and the relative error was small.
