| 英文摘要 | Eutrophication remains a critical threat to aquatic ecosystems globally. However, in-situ water quality measurements are often limited by short-duration or low temporal-frequency, resulting in long-term evolution of lake eutrophication remains largely unknown. This has led to major gaps in understanding how lakes respond to climatic, geomorphometric, and human influences at regional scales. Here, by leveraging approximately a halfcentury of in-situ water quality data measured at 135 stations in 31 Finnish lakes, we aim to provide a comprehensive, multi-decadal assessment of eutrophication evolution using four well-established trophic state indices (TSIs). Also, we utilize a random forest model to quantify the relative contribution of anthropogenic and climatic drivers to the changing TSIs across the lakes from 1980 to 2024. Our findings indicated that while countrywide average TSIs remained relatively stable over the study period, the proportion of eutrophic lakes increased significantly since the early 2010s, particularly in southern and central Finland. This indicates localized and spatially clustered eutrophication trends are not captured by national means. Spatial analysis revealed a pronounced latitudinal and elevational gradient of the TSIs, with eutrophic conditions dominating southern regions and oligotrophic states persisting in northern basins. Human activities, particularly land-use change, population density, and vegetation variation play a dominant role in the southern lakes' eutrophication, while northern lakes are more sensitive to climatic variables. In human-impacted regions, reducing nutrient inputs through targeted land-use regulation is critical, whereas climate-sensitive areas require adaptive strategies to enhance ecohydrological resilience. Our findings provide actionable insights for protecting freshwater ecosystems under accelerating environmental change. |
