根据2008年至2011年福建长乐海岸海水入侵监测资料,对该区域的海水入侵现状进行分析,发现长乐市漳港镇沙尾村——文武砂镇壶东村断面的海水入侵较严重,海水入侵区侵入陆地约1.7公里,最高氯度值16715mg/L,矿化度16.586g/L;长乐市文岭镇前董村——文岭镇石壁村断面的海水入侵程度较轻,海水入侵区侵入陆地约0.7公里,最高氯度值3499 mg/L,矿化度6.573 g/L。在此基础上着重分析了海水入侵的成因,并提出海水入侵的防控对策。
Based on the monitoring data of seawater intrusion in Changle coast in Fujian province from 2008 to 2011, the status quo of seawater intrusion in this area was analyzed. It was found that the seawater intrusion in the section of Yutong Village, Shawei Village - Wenwu Town, Zhangle Town, Invaded the land about 1.7 kilometers, the highest chlorinity 16715mg / L, salinity 16.586g / L; Changle City Wenling Town before the village - Wenling Shibingcun cross-section of the sea water less invasive, intrusion into the sea area About 0.7 km, the highest degree of chlorine 3499 mg / L, salinity 6.573 g / L. On this basis, the causes of seawater intrusion are emphatically analyzed, and the prevention and control measures of seawater intrusion are put forward.
