Taking Yuqiao Reservoir, a key drinking water source for Tianjin, as the research object, this study utilized Sentinel-2 MSI satellite data and synchronous in-situ measurements to investigate its eutrophication spatiotemporal changes from 2016 to 2023. Semi-empirical models based on the NDCI index were constructed for chlorophyll-a concentration inversion, while the QAA_RGB quasi-analytical algorithm was adopted for water transparency retrieval. The Comprehensive Trophic Level Index (TLI) was further calculated to...
