摘要
Subsurface cyanobacterial blooms are a significant source of odor problems in source water, particularly in oligotrophic/mesotrophic reservoirs. This study explores the key driving forces behind the succession between surface and subsurface cyanobacteria in Miyun Reservoir, China, using ecological niche modelling. Results indicate that water depth and surface light irradiance (I0) have a negative effect on subsurface Planktothrix sp. growth, while surface water temperature (T0) follows a unimodal effect with an optimum at 23°C. For surface Microcystis spp., temperature and the interaction between temperature and light irradiance are key factors. The study suggests that high irradiance and nutrient availability during the pre-bloom stage favor surface cyanobacteria, while the post-bloom decline of surface cyanobacteria allows for the growth and succession of subsurface cyanobacteria in deeper layers, where nutrient supply remains adequate. The growth potential of subsurface cyanobacteria is higher than that of surface cyanobacteria in shallow oligotrophic and deep eutrophic reservoirs during median light irrigation seasons.
