Chlorophyll-a concentration at Guanting Reservoir in summer(August)were analyzed.The analysis has great significance to the study of reservoir water eutrophication.The data of water temperature,water depth,chlorophyll-a concentration,and meteorological data were measured at an interval of one minute,and were analyzed.The results showed that the maximum concentration of chlorophyll-aappeared at basically the same position as that of the thermocline,and it was 1.5~2times of the surface concentration value.Chl...
