Abstract:Meteorological factors (from 1981 to 2010), water quality parameters (from 1987 to 2015), yearly initial date and duration of algal bloom (from 2000 to 2013), and research situation on algal bloom among the most eutrophic large lakes in China, including Lakes Dianchi, Taihu, and Chaohu, were compared in this paper. For meteorological factors, we included air temperature, diurnal air temperature difference, wind velocity, wind direction, atmospheric pressure, precipitation, and relative humidity. For water quality parameters, we focused on water temperature, total nitrogen concentration, total phosphorus concentration, and trophic status index. Results indicated that, Lake Dianchi in Yunnan-Guizhou Plateau has higherliability of algal bloom than that in Lakes Taihu and Chaohu, because of its meteorological characteristics including but not limited to warmer winter and spring, and larger diurnal air temperature differences during these seasons, and its water quality characteristics involving higher total phosphorous concentration. Earlier initial date of algal bloom and longer duration than the other two lakes from 2000 to 2013 proved the higher severity of algal bloom in Lake Dianchi and implied its requirement for more research attention. Investigation results on existing research situations concerning algal bloom issues among Lakes Dianchi, Taihu, and Chaohu, on the other hand, are quite disappointing. Publications on algal bloom in Lake Dianchi are much fewer than those targeted at Lake Taihu. Taking into consideration the unique meteorological and water quality characteristics of the plateau-located lake, research experience gained from flatland-located lakes cannot be applied for effective algal bloom control in Lake Dianchi, therefore, more comprehensive and in-depth research on algal bloom regarding this specific lake is required from now on, in order to truly stepwise realize the control, alleviation, and hopefully final elimination of algal bloom in Lake Dianchi. © 2018 by Journal of Lake Sciences.
