As a kind of energy mineral, the coal is the material foundation of agricultural and industrial production. It is also inseparable material foundation for social economy and an important resource of social wealth. The development and usage of the coal resources have brought huge economic profits for mankind. Meanwhile, it inevitably disturbs ecological safety .The direct occupation and destory of the land resources have changed the original environment view structure and form. Consequently, the land and ecological environment are being destroying more and more seriously. Therefore, it is vital to research into the land restoration in coal mining areas, which has been one of the dispensable tasks in developing the mining areas and ensures the sustainable development of the social environment, that is, which guarantees the effective exploration of the coal resources and the ecological protection.According to the demand of the regional sustainable development, the thesis analyzes the influences of the coal mining areas on the land resources, water-environment and infrastructures, points out that the land restoration in the coal mining areas should aim at the restoration of the land productivity and the complete restoration of ecosystem in mining areas, generalizes the applied conditions, construction techniques and construction process of the land restoration techniques such as pump drain, direct using, deepening and stacking, filling consolidation by coal gangue, and filling consolidation by fly ash. Taken reversion ecology and the mechanism of ecologic succession as important theoretical foundation, it advocates variable restoration of ecosystem especially of the cluster's to promote the coordinated growth by reshaping physiognomy, soil restructing and vegetation recovering and so on. At the same time, it proposes a scientific and reasonable programming for ecology zoning, the optimization of land resources allocation and the construction of productive and effective agricultural ecosystem. Based on engineering measures, biology measures, physical geography condition, the forms and degree of the land destruction, it constructs the model of comprehensive ecological land restoration such as the model of intensivism agriculture, the model of orchard, meadow and forestry, the model of agriculture, forestry , fishery and livestock breeding, the model of constructional land and architectural material producing, and the model of aquaculture, vegetable and ecological tour.On the analysis of the sunk areas in Da Meng Cun Town of Nei Qiu County in Hebei Province, it puts the theoretical methods into practice by land restoration and consolidation...
