摘要
尾矿库是矿山生产的重要设施,对矿山及其周边生态环境具有重大影响.为了满足尾矿库环境监管的要求,通过对谷歌地图卫星影像进行多尺度分割获取尾矿库周边居民区、农田、水体等信息,通过数字高程模型获取尾矿库周边的高程信息,通过哨兵 2 号多光谱影像并结合实验室分析检测结果确定尾矿的主要组成成分.运用多种遥感数据源可以较好地获取尾矿库及周边区域的生态环境信息,以此为依据分析尾矿对周边环境的影响,可以为尾矿库环境监管提供技术支持.
Abstract
Tailings pond is an important facility for mine production,which has a significant impact on the mine and its surrounding ecological environment.To meet the requirements of tailings pond environmental monitoring,information about residential areas,farmland,water bodies,and other geographical objects around tailings pond was obtained through multi-scale segmentation of Google satellite map,and elevation information around tailings pond were extracted by digital elevation model.The main components of tailings were determined based on Sentinel-2 multispectral imagery and the laboratory analysis.The results indicated that the ecological environment information of tailings ponds and surrounding areas could be obtained through various remote sensing data sources.These information could be used to analyze the impact of tailings pond on the surrounding environment and provide support for environmental supervision of tailings pond.
