OPTIMIZATION OF ECOLOGICAL REHABILITATION FOR IRON MINES

摘要

The study provides an optimized computer model for ecological rehabilitation of iron mines. This model includes the evaluation of the degree of land disturbance and the appropriateness of future land use. It employs double optimization method of both ecological feasibility and ecological economic feasibility to select ecological rehabilitation model or mode in the light of ecological structure and analysis of energy and material flow of the system. Thus, the unification of ecological, economic and social benefits is realized. In a typical mine site, comprehensive ecological rehabilitation for such purposes as agriculture, forestry, husbandry and fishery can be made to develop and/or reconstruct land resources in line with specific natural conditions. The study is of great significance to similar iron mines in eastern part of China to reconstruct the disturbed local ecology, restore the natural balance and optimize the rehabilitated land system.
