With the gradual implementation of policies such as dual carbon goal, the ecological status in the open-pit coal mine is also receiving increasing attention. Thus, the fraction vegetation coverage (FVC) in Xiwan mine, a typical open-pit coal located in Shanxi Province, was calculated from 2010 to 2021 using the Landsat images by the Google Earth Engine (GEE) platform. Moreover, the spatiotemporal trends were analyzed, and the vegetation disturbance and recovery were monitored and evaluated. The results show that (1) from 2010 to 2020, the overall FVC in the study area exhibited a declining trend, with the proportion of areas with extremely low vegetation coverage increasing from 14.01 to 44.97%. FVC in the outer dump sites began to increase after 2017, predominantly reaching medium-high vegetation coverage levels. (2) A significant vegetation disturbance occurred in 2015, affecting an area of 251.19 hm2, primarily concentrated in the mining pit and inner dump sites.

摘要

With the gradual implementation of policies such as dual carbon goal, the ecological status in the open-pit coal mine is also receiving increasing attention. Thus, the fraction vegetation coverage (FVC) in Xiwan mine, a typical open-pit coal located in Shanxi Province, was calculated from 2010 to 2021 using the Landsat images by the Google Earth Engine (GEE) platform. Moreover, the spatiotemporal trends were analyzed, and the vegetation disturbance and recovery were monitored and evaluated. The results show that (1) from 2010 to 2020, the overall FVC in the study area exhibited a declining trend, with the proportion of areas with extremely low vegetation coverage increasing from 14.01 to 44.97%. FVC in the outer dump sites began to increase after 2017, predominantly reaching medium-high vegetation coverage levels. (2) A significant vegetation disturbance occurred in 2015, affecting an area of 251.19 hm2, primarily concentrated in the mining pit and inner dump sites. Vegetation recovery was observed in 2019, predominantly in the outer dump sites, with the maximum restored area reaching 221.58 hm2 in 2021. (3) The influence of coal mining activities at the Xiwan open-pit coal mine on the surrounding vegetation is in the range of 500–600 m.
