摘要
通过对莱州湾地区11个剖面60多个观测井进行测定,统计分析了水样的氯度、矿化度数据,得出了莱州湾地区海水入侵的时空变化规律。结果表明,在时间上,海水入侵的状况基本上保持稳定,受月季变化影响较小;空间上,地下水水质呈从沿岸向内陆由咸变淡的梯度变化趋势,海水入侵程度由近海岸至内陆逐渐降低,入侵面积和过渡带面积进一步扩大,表明莱州湾海水入侵程度日趋严重。
The water samples of more than 60 observation wells of eleven profiles were measured.The paper analyzed and studied their variation trends with time and space.Result showed that the seawater intrusion degree was more stable in time and the influence of months was small;the degree of seawater intrusion reduced gradually from the coast to the island.Comparied with the previous research,both the affected area and the trasition area were enlarged,indicating that the degree of the seawater intrusion was more and more serious.
