Abstract

Abstract

Taking Poyang Lake, a large river-connected lake in China as an example, 10 indicators, including Chl-a and TN, were measured at six typical points in Poyang Lake from 2016 to 2018. The spatio-temporal variation characteristics of different factors in Poyang Lake were analyzed, and the driving factors of algal proliferation were determined by integrated trophic state index method and principal component analysis, combined with the hydrology and hydrodynamics, sediment and anthropogenic influence of Poyang Lake. The results showed that:COD concentration was higher in the south and lower in the north, showed a high-low-high trend from the west to the east. The trend of TN concentration was similar to that of NH₃-N, showing higher in the south and the east, and lower in the north in summer, while the distribution spread from Banghu to Duchang in the west. TP concentration was higher in the south and lower in the north, and high in both the east and west. The occurrence frequency of Melosira and Microcystis was 51.11% and 16.44%, respectively. The density of algal cells and chl-a were the highest in Banghu, which were 7.8 and 5.3 times higher than those in Hukou, respectively. Poyang Lake was mainly at a light eutrophication level during the study period. TP was the main limiting factor for algal proliferation at six sites, which had little relationship with TN. Also, water temperature and dissolved oxygen may be factors for algal proliferation in Poyang Lake. In the future, the comprehensive management of algae in Poyang Lake should be carried out by strengthening seasonal monitoring and early warning, focusing on identifying and regulating key factors at measurement points, and strengthening algal species monitoring.
