Abstract：From January to December in 2019, the samples were collected in Dongting Lake to analyze the correlation between the chlorophyll a distribution and concentration with environmental factors by using the generalized additive model (GAM). The results showed the strong temporal and spatial variations of chlorophyll a concentration appeared, annual average value was 5.77μg/L ranging from 1.00 to 67.33μg/L for the single influencing factor GAM model. The most influential factors in the variations of chlorophyll a concentration differed among seasons, with CODMn, Cond and TP for spring; CODMn, WT and Cond for summer and autumn respectively; NH4+-N and Cond for winter. For the multiple influencing factors GAM model the explanation result was better with an overall rate for 97.5% for the variations in chlorophyll a concentration. The environmental factors affecting the variations in chlorophyll a concentration ranked as CODMn>TP>Cond>NH4+-N>TN/TP, and all factors exhibited a non-linear relationship with chlorophyll a concentration.
