可拓方法在矿区土地复垦中的应用研究

Application of extension method to land reclamation in mining area

从理论上分析了基于可拓方法的土地复垦相关描述,然后提出了基于可拓的复垦土地适宜性评价方法,并通过实例进行了验证。研究结果为勉强适宜,与实际相符,表明了可拓方法在复垦土地适宜性评价中的可行性.该方法不仅可以克服在评价过程中人为因素的影响,而且可对参评因子进行量化处理,从而提高复垦土地适宜性评价的精度。

The application of extension method to land reclamation in the mining area can improve the decision level for planning. The relative description for land reclamation is firstly analyzed based on the extension method, and then a land suitability evaluation model based on the extension method is given, which is tested by an example. The result of test demonstrates that this model can obtains good result, which is more in accordance with fact. The advantages of this model are that it cannot only overcome the effect of man-made but also can quantify factors and improve the evaluation precision. The extension method will have an extensive application field in land reclamation of the mining area.
