应用于温排水影响的海洋围隔实验技术研究

Research on marine enclosure experimental technologies for thermal discharge effects

海洋围隔实验技术应用于温排水生态影响研究具有开创性。为此,将2011年7月在象山港电厂附近水域(显增温区、弱增温区和自然温度区)设置的3组现场围隔控制实验和其数据分析方法——混合效应线性模型进行介绍。该技术可对影响浮游生物生长的可能因素进行分析,能识别控制因素及交互作用因素,并建立它们与浮游生物丰度之间的响应关系,探讨温升区设置的合理性问题。该技术可作为温排水环境影响研究的技术指南之一,为环评、温排水相关的技术标准及方法制定、温排效应监测方法的优化,温排对生态环境损害的补偿估算等提供技术支持。

Marine enclosure experimental technologies for thermal discharge effecting on ecosystems was a ground-breaking study. So three enclosure ecosystems experiments placed in explicit warming water area,weak warming water area and natural temperature water area around Xiangshan Port power plant on July,2011 and the repeated measurement data analysis method,mixed effects linear model,were being introduced here. Accordingly,the study was conducted in order to analyze the possible impact factors on phytoplankton growth,identify the controlling factors and interactions,and establish the response relationship between these factors and phytoplankton abundance. Finally,the rationality of the temperature zone setting can be discussed. The study can be one of technical guidelines about thermal discharge effects on environment and provide technical support for formulating technical standards and methods of thermal discharge effect research. It can also be used in estimating ecological compensation of thermal discharge damage and so on.
