摘要
结合锦州市海水入侵相关监测资料,经现场调研勘察进一步核定海水入侵的具体范围,并全面分析海水入侵成因。结果表明:锦州市共有2处海侵区,分别为锦州市区娘娘宫街道-松山街道-建业镇沿海的部分村屯,凌海市大有街道的部分村屯;水文、地质、渤海潮汐等自然因素是导致海水入侵加剧的主要原因,拦海养殖致使入海淡水量减少和超量开采引起地下水位下降以及人为提高海平面高度是主要人为因素,最终导致咸淡水过渡带向内陆地区移动。
Based on the relevant monitoring data of seawater intrusion in Jinzhou City,the specific scope of seawater intrusion is further verified through field investigation and investigation,and the cause of seawater intrusion is comprehensively analyzed.The results show that there are two transgressive areas in Jinzhou city,which are some villages along the coast of Niangongong Street,Songshan Street and Jianye Town in Jinzhou City,and some villages in Dayou Street in Linghai City.Hydrology,geology,tidal and other natural factors in the Bohai Sea are the main reasons for the increase of seawater intrusion.The main human factors are the decrease of fresh water into the sea caused by aquaculture,the decrease of groundwater level caused by over-exploitation,and the elevation of sea level caused by human activities,which eventually lead to the migration of brackish water transition zone to inland areas.
