有害藻华（HABs）的严重性和强度日益增加，对公众健康和生态系统构成威胁，并已成为近几十年来的全球性问题。我国的相关研究大多集中在低纬度地区，如太湖、巢湖和滇池。然而，很少有人关注中国东北地区的藻类水华。作为我国重要的商品粮生产基地，随着粮食产量的逐年增加，非点源污染沿着加剧。事实上，在研究较少的东北地区，赤潮已经非常严重。从1982年到2016年，在2186张可行的陆地卫星图像中，共有271张发现了赤潮。年总检出频次从1982年的0次波动上升到2016年的11次，最高检出频次出现在2010年和2014年两次，均为29次。检测到赤潮的湖泊、水库数量和标准化赤潮面积的年总和也明显增加。这一趋势几乎与气温上升、风速减小和气压下降相一致。年频数与三个气象指标的相关系数（R2）分别为（0.274，<0.005），（0.553，<0.0001），（0.073，0.126）。此外，选取1986年、2000年和2010年的化肥施用量、工业废水和城市污水排放量、土地利用类型作为人为影响指标。综合考虑湖泊地貌和水文水动力特征，分析了东北地区赤潮时空分布格局的驱动因素。
The increasing severity and intensity of harmful algal blooms (HABs) are of great concern to public health and a threat to ecosystems and have become a global problem in recent decades. Most of the related studies in China have been focused on low-latitude areas, such as Lake Taihu, Chaohu, and Dianchi. However, little attention has been devoted to algal blooms in Northeast China. As a significant Chinese commodity grain production base, the non-point source pollution deteriorated along with the grain production increasing year by year. In fact, the HABs in the little researched Northeast China were exceedingly serious. From 1982 to 2016, there was a total of 271 out of 2186 feasible Landsat images found HABs. The annual total frequencies of the detected HABs increased in fluctuation from 0 in 1982 to 11 times in 2016, and the highest frequency was observed twice, in 2010 and 2014, and was 29 times in both years. The number of lakes and reservoirs detected HABs and the annual sum of normalized HABs area also increased obviously. The tendency was almost coherent with the rising temperature, reduced wind speed, and declining atmospheric pressure. The R2andp-valuebetween the annual frequency and the three meteorological indices were (0.274, <0.005), (0.553, <0.0001), and (0.073, 0.126), respectively. Besides, as anthropogenic influence indicators in this paper, we selected fertilizer application amount, industrial wastewater and municipal sewage discharge amount, land use type in 1986, 2000, and 2010. We comprehensively considered lacustrine morphologies and hydrological hydrodynamics and analyzed the driving factors of the spatiotemporal distribution pattern of HABs in Northeast China.
