摘要: 矿山开采过程中产生的生态环境污染问题日益突出,针对矿山生态环境的预测评价显得尤为重要。综合运用主成分分析法、灰色预测模型和初等关联函数等方法构建矿山生态环境预测模型,可以为矿业企业在未来环境保护及环保投资提供指导与借鉴。首先综合考虑环保资金投入和采矿、选矿对环境及员工的影响构建生态环境评价指标体系。主成分提取后,选取方差贡献率较高的主成分计算分析,可以得到2016年实际得分分别为-4.1776、0.4093、-0.2553以及2016年预测得分分别为-4.2926、-0.2175、0.3312。2016年生态环境评价值为-0.8861,预测值为-0.9708,2017年和2018年的预测评价值为-1.5493、-2.0511。研究结果表明:预测数据与实际数据基本一致,验证了预测模型的有效性,该矿山区域生态环境在持续改善。
