Land Cover Changing Pattern in Pre- and Post-Earthquake Affected Area from Remote Sensing Data: A Case of Lushan County, Sichuan Province

A significant improvement in land cover occurred in Lushan National Park, Sichuan Province, following the 2013 earthquake, driven by both artificial measures and natural restoration. The study, using remote sensing data from 2012 to 2020, revealed that cropland, forest, built-up areas, and bare land experienced notable changes during this period. Key ecological indicators such as patch density (PD) and landscape shape index (LSI) decreased, while the aggregation index (AI) increased, signaling a positive shift toward more stable and aggregated landscapes. This research provides critical insights for ecological management and long-term restoration planning in earthquake-affected regions.
