| 摘 要： | 海水入侵和土壤盐渍化是重要的海洋灾害类型。文章选取3个土壤采样点和3个地下水采样点,以地下水氯离子浓度和矿化度以及土壤氯离子含量、硫酸根离子含量和全盐量为监测项目,首次对惠州市大亚湾淡澳河入海口沿岸区域的海水入侵和土壤盐渍化状况进行研究。研究表明:研究区2个采样点未受海水入侵,1个采样点海水入侵程度为轻度;1个采样点为氯化物-硫酸盐型和中盐渍化土,2个采样点为氯化物型和盐土;海水入侵程度以及土壤盐渍化类型和程度与离岸距离均无相关性,但受与河口距离的影响。今后将进一步加强监测和研究,为沿海环境风险管控和海岸带整治修复提供科学依据。

| Abstract: | Seawater intrusion and soil salinization are the major types of marine disasters.3 soil sites and 3 underground water sites were selected in this paper,taking groundwater chloride concentration and salinity as well as soil chloride content,sulfate ion content and total salt as monitoring items.It was reported for the first time that the seawater intrusion and soil salinization near the estuary of Danao River in Daya Bay.According to the monitoring results,there was no seawater intrusion at 2 sites and the rest one was low-grade;one site in this monitoring area was Cl- SO42- and the degree of soil salinization was medium saline soil,the other two were Cl- and saline soil.The degree of seawater intrusion and the type and degree of soil salinization were not related to the distance from the shore,but influenced by the distance from the estuary.Monitoring and research should be further strengthened in the future to provide scientific basis for coastal environmental risk control and coastal rehabilitation. |
