Abstract: Based on the analyses of the character of the exploitation of the iron ore resource and its destruction of eco-environment in Tangshan area, this paper puts forward the patterns of land reclamation which fits for this area. The patterns include the reclamation of ecological agriculture, planting directly on the tailing bin without covering soil, reclamation of mine tailings in the pool, and improvement of the soil quality by using tailings etc. Now, over 700hm2 land has been reclaimed by taking advantage of the pattern in Tangshan and eight typical reclamation districts have been built. The rates of reclamation exceed 80% and have reached the advanced level of the world. Practice has proved that the eco-environment of the ore area has been greatly improved and the remarkable economic and social benefits have been gained.
