Abstract: On the basis of the study of regional ECC(environmental carrying capacity), taking Shenbei mining area as an example and combined with “3S” technology, this paper systematically analyzed the influencing factors of ECC, and constructed the index system of ECC of Shenbei mining area, analyzed, calculated and evaluated the ECC of Shenbei mining area. The results showed that ECC of land desertification and mine exploitation and water resource quality have been overflown with overflow percentum of -17.8%, -2.6% and -9.8%；ECC of water resource quantity is comparatively well, its potential percentum is 30.8%. The integrated ECC of Shenbei mining area is only 14.1%.The results showed that the integrated ECC of Shenbei mining area is approaching the limit of overloading.
