海水入侵和土壤盐渍化是海岸带重要的地质灾害类型之一。本文报告了2008—2010年福建省漳州市漳浦县海岸带海水入侵和土壤盐渍化状况及趋势监测结果。在漳浦县旧镇和霞美镇离岸1.4～3.9 km的监测过渡区范围,地下水（水井水）的Cl-含量为1 200～5 030 mg/L,矿化度含量为2.20～13.97 g/L,全部Cl-含量和大部分矿化度指标超过严重入侵标准值,表明监测区发生严重海水入侵。梅宅村断面过渡区,枯水期发生不同程度土壤盐渍化,但在丰水期恢复成非盐渍化;刘板村断面过渡区,除2009年丰水期监测到氯化物—硫酸盐型中盐渍化土,其他全部为非盐渍化,但在2008年和2009年枯水期,分别在离岸最远的非盐渍化区,监测到硫酸盐—氯化物型盐土和氯化物—硫酸盐型中盐渍化土,表明监测区土壤盐渍化总体较轻,但缺乏明显规律性,有待进一步监测与研究。

Seawater intrusion and soil salinization are important geological disasters in coastal belt. The status of seawater intrusion and soil salinization in the coastal belt of Zhangpu County, Zhangzhou City, Fujian Province are reported in this paper based on the monitoring results during 2008 and 2010. The water and soil were sampled from 2 transect and 3 wells in every transect 2 times every year and the content range of C1- and min- eral in water samples and PH, C1 - , SO2- in soil samples were inspected. The targets from the samples of mid- dle wells in every transect which are 1.4 and 3.9km away from the coast respectively were chosen to verdict the extent and pitch of seawater intrusion and soil salinization. Their results of C1- aiad mineral in water are between 1200 mg/L to 5 030 mg/L and 2.20 g/L - 13.97g/L respectively. All the contents of C1- surpass the standard of 1000 mg/L and most contents of mineral surpass or near the standard of 3.0 g/L, which means that serious seawater intrusion existed in the coastal belt in Zhangpu County. The monitoring also showed that the soil salinization was mild in total, but the results lacked obvious orderliness and needed to study further.
