Studying the effects of tidal phenomena on coastal plant growth is an important subject in marine ecology,design of a system that simu-lates tidal phenomena automatically in laboratory is the basis for the study. a simulated tidal system was developed for this requirement,and a de-sign scheme of upper and lower water tanks is proposed. The functional structure,hardware composition and software design of the system were in-troduced. At present,the system has been put into operation in the relevant research experiment of the State Key Laboratory of Estuarine Coast of East China Normal University,and the operation effect is good.%研究潮汐现象对沿海植物生长的影响是海洋生态学的重要研究课题,设计一套在实验室环境中可自动模拟潮汐现象的系统是这种研究的基础需求.针对这一需求开发了模拟潮汐系统,提出了一种上下双水箱模拟潮汐设计方案.介绍了该系统的功能结构、硬件组成及与软件设计.目前,该模拟潮汐系统已在华东师范大学河口海岸国家重点实验室的相关研究实验中投入使用,运行效果良好.
