摘　　要：为掌握露天采矿活动对周围生态环境的影响,以山西省朔州市3个露天矿区为例,基于植被物候视角研究露天开采对周围植被的扰动情况。利用Sentinel-2地表反射率数据集构建高频次植被指数NDVI时间序列,采用双逻辑回归(Double logistic)方法拟合重建了2023年NDVI时间序列。利用动态阈值法提取露天矿区周围的作物和植被物候期:植被变绿期(SOS)、植被衰落期(EOS)和植被生长周期(LOS)。最后创建矿区100 m缓冲区,去除矿区之间相互影响的区域,统计在单个矿区影响下的物候期变化情况。研究成果可为煤矿企业更有针对性的实施生态修复方案提供参考依据,也可为识别露天开采活动对周围植被扰动范围和程度提供新思路。To understand the impact of open-pit mining activities on the surrounding ecological environment,three open-pit mining areas in Shuozhou City of Shanxi Province were taken as examples to study the disturbance of open-pit mining on surrounding vegetation from the perspective of vegetation phenology.A high-frequency vegetation index NDVI time series was constructed using the Sentinel-2 surface reflectance dataset,and the 2023 NDVI time series was fitted and reconstructed using the double logistic regression method.Using dynamic threshold method to extract crop and vegetation phenological periods around open-pit mining areas:vegetation greening period(SOS),vegetation decline period(EOS),and vegetation growth cycle(LOS).Finally,we create a 100 m buffer zone in the mining areas,remove the areas that affect each other between mining areas,and record the phenological changes under the influence of a single mining area.The research findings provide a reference for coal mining enterprises to implement targeted ecological restoration plans and offer new insights for identifying the extent and degree of disturbance caused by open-pit mining activities on surrounding vegetation.
