【摘要】：FerryBox是一套全自动、实时的水生生态监测系统,具有多参数、低维护、低成本、监测覆盖范围广、可持续性强等诸多优点。2015年10月~2016年7月,作者通过将其安装在一条频繁返于烟台-大连之间的货船上,实现了10个月的渤海海峡水质低成本长期自动监测。监测结果表明,渤海海峡水环境因子在时空分布上存在显著的南北差异,秋季海峡南部海域的表层浊度及pH均高于中部及北部海域;冬季海峡北部海域的表层温度、盐度和浊度均大于南部海域;进入春季以后海峡中南部海域为表层叶绿素a浓度高值区。季风、黄海暖流以及渤海环流等因素是造成渤海海峡水环境因子南北差异的主要原因。春、夏季渤海海峡营养盐监测结果表明,渤海海峡营养盐的时空分布具有明显的季节性和区域性特征,在时间变化上整体呈现初春和夏末较高,在空间分布上整体呈现海峡两侧高于海峡中部。海底冷水团颗粒物的分解、藻类繁殖、地表径流以及渤海环流等,是影响渤海海峡春、夏季营养盐时空分布的重要因素。春季渤海海峡浮游生物生长受硅和磷的双重限制,夏季主要受磷限制。
[Abstract]:FerryBox is a fully automatic, real-time aquatic ecological monitoring system with many advantages, such as multi-parameter, low maintenance, low cost, wide monitoring coverage, strong sustainability and so on.By installing it on a cargo ship frequently returned between Yantai and Dalian, the author realized the long-term monitoring of water quality in the Bohai Strait for 10 months at low cost.The monitoring results show that there is a significant difference in the spatial and temporal distribution of water environmental factors in the Bohai Strait. In autumn, the surface turbidity and pH of the sea area in the southern part of the strait are higher than those in the central and northern sea areas, and the surface temperature in the northern sea area of the strait in winter.The salinity and turbidity are higher than those in the southern sea area, and the high value of chlorophyll a is found in the middle and south part of the strait after spring.Factors such as monsoon, Huang Hai warm current and circulation in Bohai Sea are the main reasons for the difference of water environmental factors in the Bohai Strait between the north and the south.The results of nutrient monitoring in the Bohai Strait in spring and summer show that the temporal and spatial distribution of nutrients in the Bohai Strait has obvious seasonal and regional characteristics, and the overall temporal variation is higher in early spring and late summer.The spatial distribution of the two sides of the strait is higher than that of the middle of the strait.The decomposition of pellets, algae propagation, surface runoff and circulation in the Bohai Sea are the important factors affecting the distribution of nutrients in spring and summer in the Bohai Strait.The growth of plankton in the Bohai Strait in spring is restricted by both silicon and phosphorus, and in summer it is mainly restricted by phosphorus.
