摘要
由于废弃露天煤矿区土地复垦过程中易受生态动态演变特征影响,导致土地复垦可行性评估结果不精准.为此,本文提出了特征融合下的废弃露天煤矿区土地复垦可行性评估算法.采用概率积分法评估土地损毁程度,分析废弃露天煤矿区土地动态演变过程,融合重金属污染、土地单元下沉和水平移动、地表沉陷特征,引进免疫克隆模型原理,构建目标适应度函数,依据免疫细胞和抗原亲和力,克隆抗体库.根据克隆操作结果,评估废弃露天煤矿区土地复垦可行性,结合地累积指数法评估沉积物中重金属污染程度.根据矿区实际情况,结合主成分分析方法评估农业、林业、牧业、渔业复垦可行性.由实验结果可知,该算法规划的不同种土地复垦空间与理想结果一致,说明该方法的评估结果精准.
Abstract
Due to the susceptibility to ecological dynamic evolution characteristics during the land reclamation process in abandoned open-pit coal mining areas,the feasibility assessment results of land reclamation are not accurate.To this end,a feature fusion based feasibility assessment algorithm for land reclamation in abandoned open-pit coal min-ing areas was proposed.The probability integral method is used to evaluate the degree of land damage,analyze the dy-namic evolution process of land in the waste gas open-pit coal mine area,and integrate the characteristics of heavy metal pollution,land unit subsidence and horizontal movement,and surface subsidence.Introduce the principle of immune cloning model,construct a target fitness function,and clone an antibody library based on the affinity of im-mune cells and antigens.Based on the results of the cloning operation,evaluate the feasibility of land reclamation in the waste gas open-pit coal mine area,and evaluate the degree of heavy metal pollution in sediment using the land ac-cumulation index method.Based on the actual situation of the mining area,combined with principal component analy-sis method,evaluate the feasibility of agricultural,forestry,animal husbandry,and fishery reclamation.From the ex-perimental results,it can be seen that the different types of land reclamation spaces planned by this algorithm are con-sistent with the ideal results,indicating that the evaluation results of this method are accurate.
