摘要:
比较了太湖、巢湖、滇池("三湖")1981-2010年间的气象要素,1987-2015年间的水质要素,2000-2013年间的年内水华起始日期与持续时间,以及与水华相关的已有研究情况.其中,气象要素包括气温、日温差、风速、风向、气压、降水、相对湿度等;水质要素包括水温、总氮浓度、总磷浓度、水体综合营养指数等.对比结果表明,云贵高原湖泊滇池因其冬、春季节气温较高且日温差较大等气象特征,以及总磷浓度较高等水质特征,相比于东部平原湖泊太湖、巢湖而言更易发生水华,且在"三湖"中水华年内起始日期最早,持续时间最长.然而,目前有关滇池水华的研究相对于"三湖"中的太湖却远远不足.鉴于滇池所处湖区的独特气象、水质特征,平原水华湖泊的研究结果难以有针对性地指导其水华控制,亟需提高滇池水华研究的系统性与深度.只有因地制宜,方有希望逐步有效控制、减轻、乃至消除滇池水华.

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.
