Spatiotemporal analysis and multiple scenarios prediction of sustainable ecosystem in China based on ecological footprint method

Autor: Longhui Xiang, Chengzhong Chen

Publikováno v: Resources and Environmental Economics. 1:71-79

Dynamic changes of sustainable ecosystem in China have been assessed with long-term series from 1949 to 2006, and the ecosystem sustainability of 30 provinces in 1986, 1996, 2002 and 2006 are analyzed with ecological footprint index (EFI) and ecologi

Multiple Scenarios Simulation of Global Ecological Footprint Based on Empirical Mode Decomposition Method

Autor: Chengzhong Chen, Longhui Xiang

Publikováno v: Open Journal of Ecology. :506-520

A nonlinear dynamic simulative model has been discussed with variable cycles of entire world per capita ecological footprint taken from 1961 to 2003. The model was further classified and decomposed and extracted by the empirical mode decomposition (E

Trends in per capita ecological footprint and biocapacity in China 1949–2013

Autor: Xuguang Ge, Chengzhong Chen, Yuan Cao

Publikováno v: Chinese Journal of Population Resources and Environment. 15:175-181

This paper proposes two concepts: the ecological footprint component index (EFCI) and the biocapacity component index (BCCI), based on the ecological footprint (EF) and Shannon entropy approaches. Per capita EFCI and BCCI in China 1949–2013 are ana
