Impacts of land use change on ecosystem service degradation within a traditional circular agroecosystem: a case study of the Honghe Hani Rice Terraces

Land use changes between 1990 and 2020 have significantly degraded ecosystem services within the Honghe Hani Rice Terraces. The study found that paddy rice areas shrank by 36.35 km² (24.83%), primarily converting to forest and cropland, which led to a decline in habitat quality despite a 16.61% increase in carbon storage. Soil retention and water yield services also decreased by 14.43% and 11.74%, respectively. Areas with high sensitivity to habitat degradation (32.71%) and geological hazards (38.82%) expanded, posing risks to the terrace system's resilience. Conversely, soil erosion-sensitive areas declined by 48.84%. The research used land use change mapping and ecosystem service evaluation models to assess these impacts, proposing pathways for optimizing and conserving traditional agroecosystem functions.
