基于GIS的铀矿山退役治理效果评价技术研究

Investigation on Effect of Uranium Mine Decommission based on GIS Technique

以北方某铀矿山为例,通过收集该铀矿山各类设施退役治理前、后不同时期的卫星遥感影像,采用地理信息系统技术对遥感影像进行解译、分析,绘制了铀矿山所在区域土壤侵蚀强度、植被覆盖度等生态图件,并结合生态环境影响评价技术导则对该铀矿山所在区域的整体生态环境质量进行了定量分析,研究结果表明,该铀矿山采取退役治理措施后,其所在区域的生态环境各项指标较退役治理前有了明显改善,体现了该铀矿山退役治理工程良好的环境效益。

This research took a uranium mine in the north China as an example.Through collecting satellite remote sensing images at different periods before and after the decommissioning of various facilities of this uranium mine,the remote sensing images of soil erosion intensity and vegetation coverage index were interpreted and analyzed by geographic information system technology.The paper conducted a quantitative analysis based on the technical guidelines for the assessment of ecological environment impact.The results showed that after the decommissioning treatment of this uranium mine,the indexes of the ecological environment in this region have been improved obviously,which reflected the good environmental benefits of the uranium mine decommissioning treatment.
