摘要
通过对蓝田县偏白村和西安东郊刘家坡黄土剖面的观测和含水量的测定,研究了黄土含水量变化.结果表明,偏白村黄土地层与刘家坡黄土地层中含水量代表了两种不同的变化类型,偏白村黄土层含水量高,红色古土壤层含水量低;刘家坡黄土层含水量低,红色古土壤含量高.黄土层比红色古土壤层更利于地下水富集,黄土层为含水层,红色古土壤层为隔水层.黄土、古土壤含水性与含水量和古气候密切相关.
Through observing the loess profile and surveying the moisture content in Pianbai village in Lantian county and Liujiapo in Xi′an, the change of the moisture content of loess strata is studied. The result shows that the moisture content of loess layer represents two kinds of change in Pianbai village and Liujiapo. The moisture content of loess layer is higher than that of the red paleosol in Pianbai village, which is contrary to that in Liujiapo. It is more beneficial to the collection of underwater in the loess layer than in the red paleosol layer. The loess layer is aquifer and the paleosol layer is aquifuge. The character of moisture content of loess and paleosol have relation with the palaeoclimate.
