Harmful cyanobacterial blooms (HCBs) are becoming more prevalent in inland waters, affecting not only the aquatic ecosystems but also the economy. This study attempted to characterize HCBs in a cool‐temperate freshwater lake and identify the causal factors controlling their proliferation. As our climate is changing in an unprecedented way, it is important to know how this climate change may alter surface runoff and streamflow, which may, in turn, affect HCBs. To this end, this research also employed a hydrologic model, Soil and Water Assessment Tool, to simulate the hydrologic conditions under various future climate scenarios. The results showed that weather conditions are more strongly related to the probable number of cyanobacteria per litre than nutrients. The change in precipitation, rather than temperature, is more important in affecting surface runoff. These results may be useful in controlling HCBs.

有害的蓝藻水华：以一个凉爽的湖泊为例

有害蓝藻水华（HCB）在内陆水域越来越普遍，不仅影响水生生态系统，而且影响经济。这项研究试图对温带淡水湖中的六氯代苯进行表征，并确定控制其扩散的原因。随着我们的气候以前所未有的方式变化，了解这一气候变化如何改变地表径流和水流量，进而可能影响六氯代苯是很重要的。为此，本研究还采用了水文模型，土壤和水评估工具，以模拟各种未来气候情景下的水文条件。结果表明，天气条件与每升蓝细菌的数量比养分更密切相关。降水的变化而不是温度的变化 在影响地表径流方面更重要。这些结果可能对控制六氯苯有用。
