三门湾增温与富营养化耦合作用对浮游植物群落结构长期变动研究

Warming and eutrophication are two of the key factors that influence the occurrence of red tide (development of marine phytoplankton) in the sea, moreover, coastal eutrophication process is an important part of the current global marine environment research. In recent years, with the establishment of the thermal power plants and nuclear power plants in Sanmen Bay, one of the main breeding bays in Zhejiang province, which led to water temperature increase, as well as the surrounding human activities did cause the eutrophication status, those factors had a synergistic effect on marine ecosystem structure and function, which would reflect in the variation trend of phytoplankton community. Therefore, it is particularly important and urgent to ascertain the relationship between phytoplankton community and warming and eutrophication. Through the analysis of nearly 40 years data of variations of phytoplankton community structure (monthly, seasonal and annual variation), temperature, salinity, nutrients and other environmental indexes in the Senmen Bay, the project will focus on the study of the changes trend and response in the phytoplankton community structure under the synergistic effect of warming and eutrophication. It will be an applied research project about the synergistic effect of human activities and global change that the project will receive data and conclusion, which will provide scientific basis to solve the changes of the ecological environment and the sustainable development of the ecosystem and resource problems and to prevent ecological environment in the Bay Area.

水体增温和富营养化是水华发生（海洋浮游植物群落变化）关键因素之一，沿海富营养化过程是当前全球海洋环境研究重要内容。三门湾是浙江重点内湾增养殖基地，近年来,三门湾核电与火电建成使用过程中，排水导致增温和周边人为活动造成的富营养化对海洋生态系统结构和功能产生协同效应，这些都会体现在浮游植物群落变化的趋势上，因此探明三门湾水体增温、富营养化和浮游植物群落之间的关系尤其重要与紧迫。本项目应用三门湾40年的浮游植物群落结构变化（月、季、年际变化），及同步实测的温、盐和营养盐等环境数据，重点研究三门湾水体增温和富营养化耦合作用下浮游植物群落结构的变化趋势和响应。本项目所获数据和科学结论，是全球变化和人为活动耦合作用的一个应用研究课题，对解决港湾生态环境的变化以及生态系统的可持续性具有重要参考价值，并为港湾海域生态环境保护提供重要的科学依据。
