摘要
为了构建更加合理的采矿活动损毁土地复垦适宜性评价模型,基于粗糙集理论的知识发现和数据发掘特点,构建了通过条件属性约简后的评价模型,获得了最小知识的有效表达,并通过线性加权组合的方法确定了各评价指标的最终权重值.该评价模型在保证评价结果有效合理的基础上,减少了传统评价模型较为烦琐和复杂的评价过程.在对丰达煤矿矿区损毁土地实地走访调查和收集资料分析研究的基础上,选取了具有一定代表性的评价单元,进行土地复垦适宜性评价工作.评价结果表明:构建的基于粗糙集理论的评价模型对于损毁土地复垦适宜性评价的结果准确、合理,基本可以满足实际生产需求.
Abstract
To build a more reasonable evaluation model for the suitability of land reclamation damaged by mining activities,leveraging the knowledge discovery and data mining capabilities of Rough Set Theory(RST),a model for conditional attribute reduction was developed to effectively express the minimal knowledge.The final weight of each evaluation criterion was determined using the linear weighted combination method.The evaluation model simplifies the complex and tedious calculation process while ensuring the effectiveness and rationality of the evaluation outcomes.Based on field surveys and analysis of land damaged in the Fengda coal mine area,evaluation units with representative characteristics were selected for assessing land reclamation suitability.The results demonstrate that the Rough Set Theory-based evaluation model is accurate and rational,and can basically meet the actual production demand.
