【摘要】：为了解滦河入海口三角洲地区地下水盐度及土壤盐渍化情况,对该区域进行了地下取水、取土测试。共布置17个浅层地下水取样点、53个深层地下水取样点及20个土壤取样点,测试水样的TDS及土壤中水溶盐的易溶盐总量,K~+,Na~+,Ca~(2+),Mg~(2+),Cl~-,SO_4~(2-),HCO_3~-,CO_3~(2-)。研究结果表明:研究区范围内淡水区域占总研究区域的50%;深层地下水TDS差异较小,且均为淡水;盐渍土类型多为氯盐渍土和亚氯盐渍土;土壤易溶盐总量整体上在各个深度处由西北向东南逐渐增加,土壤盐度的影响因素是浅层地下水;土壤易溶盐含量在局部(位置)较低。研究结果可为地下水资源及土壤资源开发利用提供一定参考。
[Abstract]:In order to understand the salinity of groundwater and the salinization of soil in the estuary delta area of Luanhe River, a total of 17 sampling sites of shallow groundwater, 53 sampling sites of deep groundwater and 20 soil sampling sites were tested in this area. The TDS of water sample and the total amount of soluble salt of water-soluble salt in soil were measured. The types of saline soil are mostly chlorinated saline soil and chlorinated saline soil, the total soluble salt content of soil increases gradually from northwest to southeast in every depth, and the influence factor of soil salinity is shallow groundwater. The content of soluble salt in soil is relatively low. The results can provide some references for the development and utilization of groundwater resources and soil resources.
