基于“国家公顷”的生态足迹模型研究

Analysis of Ecological Footprint Based on National Hectare Model

简要介绍以"国家公顷"为计量单位计算生态足迹的模型,并用"国家公顷"和"全球公顷"2种方法分别对福建省2011年生态足迹进行计算。结果表明,福建省2011年生态足迹采用"国家公顷"方法计算的结果为1.152 383 nhm2,"全球公顷"方法计算结果为2.083 948 ghm2;人均生态承载力前者为0.350 978 nhm2,后者为0.555 885 ghm2;人均生态赤字前者为0.801 405 nhm2,后者为1.528 063ghm2。对2种计算方法的结论差异进行分析,进一步说明计算和研究"国家公顷"生态足迹的应用价值和意义。

This paper introduces the ＂national hectare＂ ecological footprint model.The ＂national hectare＂ ecological footprint and the ＂global hectare＂ ecological footprint in 2011 in Fujian were calculated.The results show that the ＂national hectare＂ ecological footprint per capita is 1.152 383 nhm2,the ＂global hectare＂ ecological footprint per capita is 2.083 948 ghm2.The ＂national hectare＂ ecological capacity per capita is 0.350 978 nhm2,the ＂global hectare＂ ecological capacity per capita is 0.555 885 ghm2.The ＂national hectare＂ ecological deficit per capita is 0.801 405 nhm2,the ＂global hectare＂ ecological deficit per capita is 1.528 063 ghm2.The differences between two kinds of calculation methods are analyzed to illustrate the application value and research significance of the ＂national hectare＂ ecological footprint model.
