“省公顷”生态足迹模型的均衡因子和产量因子计算--以福建省为例

摘要

Objective] To research the calculation of equivalence factor and yield factor of ecological footprint based on provincial hectare. [Method] Based on the global hectare models and national hectare models, the provincial hectare ecological footprint model was established. It could be used to calculate the ecological footprints of middle and small spatial scale .This paper expounded the meaning and calculation methods of equivalence factor and yield factor of provincial hectare ecological footprint model .Equivalence factors and yield factors of biologi-cally productive land and water in the year 2014 were calculated through this method, using the example of Fujian Province.[Result] Accord-ing to the calculation results, the equivalence factors of Fujian of 2014 were that:cropland was 3.683 phm2/hm2, forest was 0.382 phm2/hm2, pas-ture was 0.188 phm2/hm2 , fishery water was 0.385 phm2/hm2 , the results were very different from the values with global hectare model and national hectare model.Yield factors of cities in Fujian Province were different to each other .[ Conclusion] Values of equivalence factors and yield factors reflected the actual situation of Fujian Province.As a result, equivalence factor and yield factor corresponded to provincial hectare should be used to analyze ecological footprint in provincial range.%[目的]计算福建省“省公顷”生态足迹模型的均衡因子和产量因子。[方法]在“全球公顷”和“国家公顷”的模型基础上建立“省公顷”生态足迹模型，明确“省公顷”模型中均衡因子和产量因子的计算方法。以福建省为例，计算了2014年各类土地的均衡因子和各地市各类土地的产量因子。[结果]福建省“省公顷”生态足迹模型的均衡因子：耕地为3．683 phm2／hm2，林地为0．382 phm2／hm2，草地为0．188 phm2／hm2，水域为0．385 phm2／hm2，与“全球公顷”和“国家公顷”模型下的数值存在较大差异。福建各地市同类型土地的产量因子也各异。[结论]该研究计算出的均衡因子和产量因子客观地表达了福建省的实际情况，存在的差异是合理的。在进行省域层面的生态足迹分析时，用“省公顷”对应的均衡因子和产量因子计算，相对误差较小。
