莱州湾东南沿岸地下水水位动态与海水入侵相关规律研究

Interrelation between groundwater level Regime and sea water intrusion in eastern

本文在莱州湾东南沿岸。用蒸发量、降水量和开采量指标实测资料建立了它们与地下水位负值区的相关模式；通过建立地下水位负值区面积与海水入侵面积之间的回归模型，揭示了地下水位负值区的产生和扩大是导致海水入侵发生和发展的主导因素，并用量化指标加以反映。最后对海水入侵的发展规律和防治措施进行了讨论。

In this paper,two interrelation models between the area of negative value of groundwater level(below sea level )and evaporation, precipitation and exploitation values in eastern and southern coasts of the Laizhou Bay are shown.Linear models of sea water intrusion affected by groundwater levels are set up by using regression analysis. It is made clear that the area of negative value of groundwater level is the major factor that brought about seawater intrusion.These relations may be expressed in data indexes. At last,the development trend and preventive measures of seawater intrusion are discussed.
