Monitoring ecosystem restoration of multiple surface coal mine sites in China via LANDSAT images using the Google Earth Engine

露天采矿（露天开采）场地的恢复是实现全球生态系统恢复目标的关键。随着数据可用性和技术的提高，大规模地将恢复监测从单个矿点扩展到多个矿点已成为可能。本研究为监测多个矿场的恢复效果提供了一种新方法，并向政府管理人员提供了制定矿山恢复计划和可持续采矿发展计划的信息。

Reclamation of open-pit mining (surface mining) sites is critical to achieving global ecosystem restoration goals. With the advancement of data availability and technology, scaling up restoration monitoring from individual mining sites to multiple sites on a large scale has become feasible. This study presents a novel method for monitoring the restoration efficacy of multiple mining sites, and provides actionable information for government managers to formulate mine reclamation plans and sustainable mining development strategies.
