Abstract:

We use the frequency analysis, theoretical analysis, and expert consultation methods to build an index system, and estimate the capacity of the sustainable utilization of energy and mineral resources in Wu-Chang region by AHP. The conclusions are as follows: 1) the indexes of the resources scale and support system show significant fluctuations, forming troughs in 1999 and 2005, respectively; 2) the economic resources system index shows an upward trend; 3) environmental pressure and environmental management system indexes show obvious rising phase characteristics; and 4) the sustainable capacity indexes of the energy and mineral resources utilization in Wu-Chang region show steady increasing trends.

Key words: energy and mineral resources, sustainable utilization, competency assessment, AHP, Wu-Chang region
