迄今,世界上对海水的入侵问题还未获得解决。为了使海岸地区与三角洲地区供水问题得以保证,需对海水入侵盐份进行预告,并采用有效工程予以控制,这对沿海地区的开发与开放都具有重要意义。 一、盐份的来源 海岸地区或三角洲地区盐份来源颇多,除海水入侵外,还有低洼地含盐地下水的渗漏、由盐土中扩散的盐份、农田回归水中排出的盐份等。大自然中也有大气盐份供给,但其量甚微,可以忽略不计。 伴随着潮汐、海浪向海岸和河口三角洲入侵的盐份,其影响大、范围广,是要着重研究的对象。至于 To date, the world’s invasion of seawater has not yet been solved. In order to guarantee the water supply in the coastal area and the delta area, it is necessary to make a notice of salt intrusion into the sea water and control it with effective engineering. This is of great significance to the development and opening up of the coastal areas. First, the salt source Coastal or delta salt source quite a lot, in addition to sea water intrusion, there are low-lying groundwater seepage of groundwater, salts spread from the saline soil, farmland return water discharge of salt and so on. There is also atmospheric salt supply in nature, but its quantity is negligible. With the tide, the waves invaded the coast and estuarine delta have great influence and a wide range of salinity, which is the object of study. As
