城市尺度生态足迹模型应用中不同参数选择的影响分析
Analysis on the Effect of Valuation of Various Parameters on Application of Ecological Footprint Model on the Urban Scale
摘要
Abstract
There were different valuations of equivalence factor,yield factor,average yield when ecological footprint（EF） model was applied on the scale of urban.This paper analyzed the effect of various parameters on the connotation of EF model and the result of operation.Based on the analysis of application conditions and effectiveness,there were fuzziness processing of error and weakening of worldwide correlation.Consumptive source should be decomposed to reflect regional characters in ＇national hectares＇ EF model.Analysis on scale effect concluded that there was a paradox between spatial correlation and regional character.By analyzing connation of parameters and defects of model,the problems of equivalence factor and yield factor were discussed on calculation method,and it was pointed that average yield provided worldwide correlation to EF model.Without considering demonic trade and artifactitious products trade,there was a defect in trade-correction of urban scale ecological footprint model.The results of this study would provide some suggestion on perfecting the EF theory and methodology.关键词
