摘　　要：To investigate the ecosystem damage and environment pollution resulted from coal resources exploitation,based on remote sensing image,the landscape pattern was quantitatively analyzed with GIS and landscape pattern analysis software FRAGSTATS by utilizing multiform landscape pattern indexes,such as patch area,patch circumference,patch number,fractal dimension,fragmentation index,connectivity index and so on. Results indicate that the restored landscape type occupies the control status and accounts for the majority of the whole area,and needs to be further restored and adjusted because of its internal body with smaller patches,lower fractal dimension and better connectivity. The landscape type without restoration has destroyed the ecology and beauty of the whole landscape. In addition,some suggestive instructions for restoring various kinds of patches are put forward according to the quantitative analysis.To investigate the ecosystem damage and environment pollution resulted from coal resources exploitation, based on remote sensing image, the landscape pattern was quantitatively analyzed with GIS and landscape pattern analysis software FRAGSTATS by utilizing multiform landscape pattern indexes, such as patch area, patch circumference, patch number, fractal dimension, fragmentation index, connectivity index and so on.
