Analysis of Hefei city’s ecological economic system---based on Morlet wavelet transformation

Author(s): Li Ying, Na Ming, Liu Fu

Based on the energy theory, this paper researches Hefei city‘s 1991-2012 urban ecoeconomic system energy indices, adopts Morlet wavelet transformation to empirically study the environmental load ratio (ELR). The results show that Hefei’s current urban eco-economic system is characterized by typical high environmental pressure load, and the ELR has a 12-year characteristic time scale, and that the environmental load mutated intensely in 1994, 2002 and 2010. The paper also analyzes the mutation causes and puts forward the corresponding countermeasures.
