Dynamics and drivers of phytoplankton in Lake Hulun

Li Xingyue, Sheng Zhang, Yü Liu, Lu Zongfu et autres

湖泊中浮游植物过度生长繁殖引起的水华现象日益频繁，严重威胁湖泊生态环境的健康与安全。近年来呼伦湖蓝藻水华覆盖面积有扩大的趋势，2022年呼伦湖蓝藻水华最严重时几乎覆盖了整个湖面，本文分别在春、夏和秋季调查了湖泊表、中、底层水体的浮游植物种类、细胞密度、生物量和相关水质指标，共鉴定出浮游植物193种，隶属于8门113属，优势种共14种，物种组成表现为绿藻—硅藻—蓝藻型，其中春、秋季浮游植物种类数基本相当，夏季最少，但夏季的细胞密度最高，春、夏、秋季的浮游植物生物量分别为686、510和166 mg/L。春季浮游植物Shannon-Wiener多样性指数最高，夏季Margalef丰富度指数最高，春季Pielou均匀度指数最高，呼伦湖浮游植物群落特征及其季节性差异是湖泊水环境条件和气象因素共同作用的结果，相关性分析结果表明，主要影响因素依次为水温、总氮、总磷、pH、溶解氧、气温、蒸发量和风速等。

Characteristics of renal amide proton transfer imaging in a healthy population

Sheng Zhang, Xia Wang, Xiaofan Liu, Chanjuan Yu et autres

Motivation: The changes in renal protein levels are closely related to physiological and pathological functions. Amide proton transfer weighted (APTw) imaging has the function of non-invasive and targeted detection of tissue-free proteins or peptides and is of great significance in the preliminary …
