英文摘要	Quantification of Land‐Use and Land‐Cover (LULC) changes associated with energy extraction footprints plays an important role in reclamation performance assessment, compliance monitoring, and sustainable land management practices. For regulatory planning and decision making purposes, it is crucial to understand the types and representation of disturbance present on the landscape related to energy footprints (i.e., oil, gas, and coal mining activities), non-energy footprints (i.e., other infrastructure), cutblocks, and wildfire. In this study, Landsat multispectral datasets were analysed using advanced classification and unmixing algorithms to calculate LULC changes associated with these disturbance agents from 1985 to 2015 in the Upper Peace Region, one of the major oil and gas exploration sites in Alberta, Canada. Based on 5-year intervals throughout this 30-year study, seven epochal LULC maps and a cumulative land disturbance map were produced with 82 % and 89 % overall accuracies, respectively, based on extensive and multisource, independent validation. Assessment of multiple disturbance regimes and time-series trajectories with high accuracies in this complex environment was vital to document and quantify disturbance, vegetation re-establishment, succession, and reclamation. Results indicate that more than 60 % forest loss (coniferous and deciduous) occurred due to harvesting and less than 20 % forest loss occurred due to energy and non‐energy footprints. An assessment of the current state showed 40–60 % of cutblocks and burned areas returned as immature forest and wetland and 15–20 % recovered to forest, accounting for successional processes that take time for the re-establishment of trees following disturbance. Out of total energy footprints, 8 % recovered as shrubland and 16 % recovered as forest, with almost no sign of vegetation recovery evident in non‐energy footprints (e.g., urban and long term industrial land use). The highest area of land disturbance (3412 km2) was over coniferous forest with 5-year disturbance areas of 55 km2, 65 km2, 70 km2, and 295 km2, associated with, respectively, wildfire, energy development, non‐energy footprints, and harvesting. This type of LULC investigation informs land‐use threshold management for energy footprints by identifying and partitioning key disturbance agents into land use. Knowledge of change type and land use enables insights on long term implications of the changes present and serves to guide sustainable development, environmental protection, and informing forward looking land use future state simulations. © 2020
