Abstract:

The main eleven coal mining areas in Jilin Province were selected for this research. With the method of landscape ecological risk analysis, CBERS remote sensing images obtained in 2008 were used as the main data source, to calculate the indices of landscapes pattern of different coal mining areas and draw the distribution map of the ecological risk. Comparative analysis of ERI between coal mining areas, the values of the mining areas in central Jilin Province are higher than those in south and east parts. The ERI of Jiaohe and Shansonggang mining areas with values of 0.360 2 and 0.321 0, respectively, are significantly higher than others.

Key words: landscape pattern, ecological risk, “3S&rdquo, technology, coal mines
