Abstract: In order to utilize resources reasonably and improve the utilization rate and the quality of mining development,it has important theoretical and practical significance to demonstrate and evaluate the supply capacity of mineral resources scientifically.This paper has constructed the evaluation model of the supply capacity of mineral resources basing on the fuzzy level analysis method (FAHP) ,which combines the qualitative and quantitative methods.And taking the historical data of cobalt resources from 2006 to 2015 as an example,the supply capacity of cobalt resources is analyzed.Meanwhile the resource endowment，supply - demaond market and political environment are taken as the evaluation criterion.Through analyzing the evaluation indexes，the evaluation value of the supply capacity of cobalt resources is below 1，and the downward trend is shown year by year.It shows that China's supply capacity of cobalt resources is on the weak side，and it will remain at a low level in the next few years.
