A. The SHs, WS, and TP concentrations controlled t...
A. The SHs, WS, and TP concentrations controlled the bloom dynamics during the dry season, among which the TP concentration was the most important factors, whereas the TN and TP concentrations were the primary factors during the rainy season. B. Interannual analysis revealed that the phytoplankton biomass increased with increases in air temperature and TP concentration, with TP concentration as the main contributing factor. C. The results of our study demonstrated that both meteorological factors and nutrient levels had important roles in controlling cyanobacterial bloom dynamics. D. All of these results suggest that both climate change regulation and eutrophication management should be considered in strategies aimed at controlling cyanobacterial blooms. E. In summary, we analyzed the effects of meteorological factors and nutrient levels on bloom dynamics in Lake Dianchi to represent the phytoplankton biomass. F. Further studies should assess the effects of climate change and eutrophication on cyanobacterial bloom dynamics based on data collected over a longer duration and more frequent and complete variables, and appropriate measures should be proposed to control these blooms. G. Decreasing nutrient levels, particularly the TP load should be initially considered during the entire period and during the dry season, and decreasing both the TN and TP loads should be considered during the rainy season. H. However, the relative importance of these factors may change according to precipitation patterns. 1. 2. B 3. A 4. G 5. 本题只填写5. 所对应的一个字母序号
