Conclusions of the study
In this study, a classification model of aquatic vegetation and water bodies in East Lake Taihu was proposed, and a chlorophyll a inversion model was established. From 2017 to 2022, the distribution of aquatic vegetation in East Lake Taihu has obvious spatiotemporal heterogeneity. In the long run, the concentration of chlorophyll a in open water is mainly affected by the concentration of nutrient, the intra annual concentration of chlorophyll a is mainly determined by temperature and precipitation, and the algae source, light and wind field are the main factors affecting the spatial distribution of chlorophyll a in the short term.
