为探讨三峡水库调度运行背景下,库区回水区营养盐和叶绿素a时空变化及其相互关系,于2013年5月~2014年5月在三峡库区北岸最大、也是库区水华频发的支流——澎溪河的回水区高阳平湖进行了定点和高频监测.结果表明水体热分层是高阳平湖水华发生的诱导因素.高阳平湖水体热分层发生于春季(3月初),消亡于夏末(9月中旬),冬季没有分层.2014年春季,随着水体分层的发生和发展,表层叶绿素a在69 d内从14.92μg·L-1骤增至183.73μg·L-1,并暴发水华,之后叶绿素a随着混合层深度增加而下降.水体没有分层时,表、中和底层营养盐浓度相近;水体分层之后,各层磷浓度有了明显差异,表层和底层总磷浓度相差(0.18±0.04)mg·L-1.高水位期(9月至次年4月),高阳平湖硝氮和溶解性磷高于低水位期(5~8月)的含量,分别占总氮、总磷浓度的71.4%~95.4%和42.7%~94.4%,是总氮和总磷的主要组成部分,干流倒灌输入的硝氮和溶解性磷是其主要来源.

Influenza is one of the major respiratory diseases in humans. Macau is a tourist city with high density of population and special population mob.lity. The study on the epidemiological characteristics of influenza in Macau should b.ing great value for preventing influenza in tourist cities like Macau in the world. In this study, we collected a total of 104,874 samples with influenza-like illness(ILI) in Macau from 2010 to 2018. Chi-square test and b.nary multivariab.e logistic regression were used to investigate the epidemiological characteristics of influenza A and b.in Macau. Among these ILI samples, the overall positive rate is 17.17% for influenza A and 6.97% for influenza b. The epidemics of influenza in three years(i.e., 2012, 2017 and 2018) differ from the remaining years(i.e., normal years). In a normal year, influenza A occurs year-round whereas influenza b.is seasonal. Our research shows significant differences in influenza infections b.tween different age groups in normal years. Interestingly, our analysis shows no significant difference b.tween locals and tourists in influenza A and b.infection in a normal year, whereas the odds of influenza A in tourists were significantly higher than those in locals in July 2017 and the odds of influenza b.in tourists were significantly higher than those in locals in January–Feb.uary 2012 and January–Feb.uary 2018. This is possib.y attrib.ted b. the policy of free vaccination to everyone in Macau. These findings should b. valuab.e for preventing influenza in not only Macau b.t also the world.
