摘要

自1997年以来，CNR-ISMAR每月收集威尼斯泻湖北部和中部流域的水化学和浮游植物数据。自2007年以来，这些数据一直是国际长期生态系统研究数据库的一部分，有助于填补泻湖环境研究的空白。通过分析我们的时间序列（1998-2017），我们能够观察到由于气候趋势导致的水温上升，主要由于无机溶解氮营养素的输入减少导致的营养状态下降，以及与大型植物（大型藻类和海草）生物量增加相关的透明度和溶解氧的增加。最后，观察到浮游植物生物量减少，海草和大型藻类覆盖率随之增加。目前和未来的研究将有助于评估威尼斯泻湖生态系统对人为压力和全球气候变化的反应方式。

Long-term dynamics in nutrients, chlorophyll a and water quality parameters in the Lagoon of Venice

Since 1997, CNR-ISMAR has been collecting monthly hydrochemical and phytoplankton data in the northern and central basins of the Lagoon of Venice. The data have been part of the International Long-Term Ecosystem Research (LTER) database since 2007, helping to fill a gap in lagoon environmental studies. Analysing our time series (1998-2017), we were able to observe a rise in water temperature due to climate trends, a reduction in trophic status mainly due to the lower input of inorganic dissolved nitrogen nutrients and an increase in transparency and dissolved oxygen related to the increased biomass of macrophytes (macroalgae and seagrasses). Finally, a reduction in phytoplankton biomass and an accompanying increase in seagrass and macroalgal cover were observed. Present and future studies will help to evaluate the ways in which the Lagoon of Venice ecosystem responds to anthropogenic pressures and global climate change.

期刊介绍： Scientia Marina is the successor to Investigación Pesquera, a journal of marine sciences published since 1955 by the Institut de Ciències del Mar de Barcelona (CSIC). Scientia Marina is included in the Science Citation Index since 1998 and publishes original papers, reviews and comments concerning research in the following fields: Marine Biology and Ecology, Fisheries and Fisheries Ecology, Systematics, Faunistics and Marine Biogeography, Physical Oceanography, Chemical Oceanography, and Marine Geology. Emphasis is placed on articles of an interdisciplinary nature and of general interest.
