Abstract: This paper reported the methods of ecological damage prediction and restoration in Hulun Buir Grassland by overlaying graphics and analogizing, taking as Wumuchang coal mine for an example. The project region would be divided into five parts, including subsidence region, surface plant, gangue field , transportation region and linear project region according to seat of settlement and land utilization. The area of the region is 5638.24 hm2. The area is 4244.67 hm2 that would be influenced by the settlement. Settlement would happen in half of the region, which would translate into the terrestrial ecosystem from aquatic ecosystem, the other parts of the region would subsided and cracked. These damaged lands could be restored by regulating land and planting trees and grass. The area of uninfluenced region would be 1393.58 hm2, including four parts besides the settlement region. It would destroy the plant cover and exacerbate soil and water loss. Excepting take measure of protecting, some other methods like land restoration and water and soil conservation also be made.
