矿山环境遥感综合评价指标的研究

A Study on the Synthetic Evaluation Index of the Mine Environment Remote Sensing

矿山开发能造福人类,同时也会造成生态环境破坏,影响恶劣的会危及人类的生命安全。矿山开发引起的环境污染是一个复杂、系统的变化,任何单一因素和瞬时指示指标都无法给出整个环境系统的变化趋势。遥感数据具有区域性与周期性的特点,利用遥感技术进行矿山环境监测具有很强的优势,是人们研究的重点之一。本文通过建立矿山环境小流域的环境模型,利用时间序列的遥感数据,构建出环境遥感综合评价指标。采用本指标对江西德兴铜矿基地进行了应用研究,结果显示该方法具有较好的指示效果,计算出的遥感综合评价指标可作为环境监测因子及矿山环境影响的定量评价指标。

It is Mine-exploitation that can lead to the environment deteriorated or can further threaten the security of human life while it can bring wealth to the mankind. It is a complicated and systemic effect resulted from Mine-exploitation and the variation tendency of the whole environmental system can＇t be illustrated by any single factor or instantaneous environment instruct index. The remote sensing data have the characteristics of space and periodicity. It is important to study how to monitor the change in mine environment with remote sensing. Utilized the local environment model and the remotely sensed data, the paper set up the synthetic index environment remote sensing. Through application in the copper mine in Dexing city, the synthetic index can be treated as an indicator to show the degree of pollution resulted from mine exploitation.
