As the mining industry plays a vital role in the development of the national economy in China，it is of great importance to analyze spatial distribution characteristics of illegal mining sites of mineral resources and formation mechanisms in eastern Hubei to restrain illegal activities and realize effective protection and rational utilization. By using map delineation data spanning 2011 to 2014 on illegal mining sites obtained via integration of remote sensing image interpretation，field investigation and adopting methods like spatial interpolation，kernel density analysis，buffer area analysis and gravity center model，spatial transfer characteristics of illegal mining sites are revealed from two levels and three aspects，namely the density distribution of illegal mining sites of all mineral resources，main illegal minerals and the gravity movement of illegal mining sites. It was found that in the study area，illegal mining sites have been concentrated in Daye city and Yangxin county，following a trend of shifting to the fringe of Daye city and Tieshan district. But the illegal focus of metal minerals remains almost constant and limestone for building is being transferred to Yangxin county year by year. These patterns are influenced mainly by the inherent characteristics of mineral resources，traffic conditions，the fringe of different administrative units and rigid demands of economic development. The gravity centers of illegal mining sites present Z type transfer and the gravity movement is related to changes of illegal mining quantity in different regions and the distribution of important minerals caused by regulatory oversight.
