【摘要】：矿产资源开发会对周围的水系和土壤产生不同程度的重金属污染。以某铜矿为例,实地采集水系和土壤样品,获取Cu的含量,结合GIS和遥感技术提取矿区高程、坡度、与矿点欧氏距离、汇流量等环境因子,并分析这些因素与Cu元素含量的分布规律:水系有降解作用,水系中Cu元素更容易富集在离采矿点距离较近、地势较高、地形较为陡峭、汇流量较小的水系上游。土壤中Cu元素更容易富集在地势较低、地形较为缓和的水系下游沿岸。总结出金属元素的分布规律及迁移规律,为同类型污染分布研究提供借鉴,使得采集研究数据更具针对性,同时为矿产资源合理开发利用提供决策依据。
[Abstract]:The exploitation of mineral resources will pollute the surrounding water system and soil to varying degrees. Taking a copper mine as an example, the water system and soil samples were collected in the field to obtain the content of Cu. The environmental factors such as elevation, slope, Euclidean distance and sink flow were extracted by GIS and remote sensing technology. The distribution of Cu and Cu in the water system is analyzed. The Cu element in the water system is easier to be enriched in the upper reaches of the water system, which is closer to the mining point, higher in topography, steeper in topography and smaller in current concentration. The Cu element in the soil is easier to be enriched along the lower reaches of the water system with lower topography and more moderate topography. The distribution and migration rules of metal elements are summarized, which can provide reference for the study of the distribution of the same type of pollution, make the collected research data more targeted, and provide a decision basis for the rational exploitation and utilization of mineral resources.
