Abstract:Based on the causes, characteristics and measures of vulnerability of environmental-economic system index of evaluation system for coupling degree was constructed in a mining city-Tongling. The model of evaluation system was constructed from the three-dimensional space and used the grey slope similarity incidence to evaluate the main coupling factors. The results showed that from 2002 to 2009, Tongling’s environmental-economic system went through the weak coupling degree to high coupling degree, and the coupling degree was increased. The main factors of the coupling environmental-economic system were economic growth and the improvement of environmental quality, and the main limiting factors were the slow development of tertiary industry, the environmental protection investment and insufficient management in solid waste.
