海南岛南部沿岸地下水水化学要素变化及海水入侵特征OACSCDCSTPCD
VARIATION IN CHEMICAL ELEMENTS OF GROUNDWATER ALONG THE SOUTH COAST OF HAINAN ISLAND AND SIGNIFICANCE TO SEAWATER INTRUSION
对位于海南岛南部滨岸测井地下水进行了大小潮周日取样及其化学测试.结果显示,化学要素含量及变化特征随潮期、测井位置而变化,由于所处环境的不同,QZ2和QZ5监测井的K+、Na+、Ca2+含量相近,而Mg2+的差异较明显,前者平均高出后者18.82％,表明QZ2监测井受到海水入侵.QZ2、QZ5监测井阳离子以Na+、阴离子以C1-占优,Na+所占平均比例为83％～85％、C1-为87％～88％,显示出海水的影响;QZ3监测井以HCO3-占优,比…查看全部>>
The data of 2014 from monitoring wells in South Coast of Hainan Island was studied during the times of neap tide and spring tide.Variation in chemical elements of the groundwater is adopted for revealing its relation with seawater intrusion.Our results show that chemical element concentration varies with tidal cycles,location of wells and surrounding environment.In the wells of QZ2 and QZ5,the contents of K+,Na+,Ca2+ are quite close,but Mg2+ is obviously dif…查看全部>>
