中文摘要：

通过设计一套室内平板示踪装置系统和操作方法,突破了传统装置系统忽略或简化淡水流量、潮汐等条件的局限,将这些因素加以考虑和控制,并利用设计的拍照和照明系统做到了实验实时监控,从而较好地模拟出不同条件下海岸带盐水入侵、海岸水库脱盐和盐水入侵的过程.整套实验装置实验条件易于控制,从而保证了实验过程的连贯和有效.通过对照实验照片数据的分析,得到了地下水-海水的交换过程和海水入侵的相关影响因素,对于潮汐影响下的盐水入侵机理给出了较好的揭示.

英文摘要：

Coastal zone, as an important area for human beings＇ produclion activities and ecotone, has been affected by severe seawater intrusion and groundwater pollution over the past few years. There is an urgent need to reasonably and effectively address these prominent problems. Through designing a device operation syslem and relevant experimenlal methods, factors thai have been ignored or simplified in most of previous studies can be considered and controlled, such as tidal oscillation and inland freshwater input. The lighting and photographing systems can realize real-time monitoring of the experimental processes, such as the seawater intrusion in unconfined coastal aquifers and the desalhlation in coastal reservoirs. The experimental conditions are easy to be controlled to ensure the processes consistently and effectively. Analysis of the experiment photos provides insight into the exchange processes between groundwater and seawater as well as relevant factors that affect sue, h processes, hence the mechanism of seawater intrusion affected by tidal oscillation can be well demonstrated. The research resuhs and findings provide good approaches and ideas for further research and they offer technical support for the solution of problems of the exploilation and utilization of coaslal zones and water crisis.
