基于博弈论和云物元模型的矿山塌陷土地复垦适宜性评估研究

Study on reclamation suitability evaluation of mine subsidence land based on game theory and cloud matter element model

  • 摘要: 针对矿山塌陷土地复垦适宜性评估指标因素的模糊性和随机性,构建博弈论综合赋权-云物元模型。该模型结合矿山实际情况,从地形环境、水利环境和土壤环境3个方面划定11个二级评估指标,采用遗传层次分析法和变异系数法分别计算各评估指标的主、客观权重,再通过博弈论计算得到指标综合权重,并将云模型引入物元模型。将所建立的模型应用于广西凤凰山银矿,计算了一级指标关联度和综合关联度,并进行土地复垦适宜性评估。结果表明:1#塌陷区和6#塌陷区复垦为林地的适宜性评估等级为“勉强适宜”;2#塌陷区、3#塌陷区、4#塌陷区、5#塌陷区和7#塌陷区复垦为林地的适宜性评估等级为“中等适宜”。评估结果与现场调研情况相吻合,可为矿山塌陷土地复垦工作实施提供新的思路。

     

    Abstract: In view of the fuzziness and randomness of the evaluation index factors of mine subsidence land reclamation suitability, a comprehensive weighting-cloud matter element model based on game theory was constructed.Combined with the actual situation of the mine, the model divides 11 secondary evaluation indexes from three aspects, including topographical environment, water conservancy environment and soil environment.The subjective and objective weights were determined through genetic algorithm and analytic hierarchy process (GA-AHP) and coefficient of variation method (CV), respectively.The comprehensive weight of the index was calculated by game theory, and the cloud model was introduced into the matter-element model.The model was applied to the Fenghuangshan Silver Mine in Guangxi, the correlation degree of primary index and comprehensive correlation degree were calculated, and the suitability of land reclamation was evaluated.The results show that the reclamation suitability evaluation grades of the subsidence land No.1 and No.6 for forest land were "barely suitability", while the reclamation suitability evaluation grades of the subsidence land No.2, No.3, No.4, No.5 and No.7 were "medium suitability".The evaluation results are consistent with the field investigation, thereby providing a new idea for the implementation of mine subsidence land reclamation.
