摘要
依据对黄土地层的孔隙度及颗粒组分等实测资料 ,初步认识到黄土的孔隙度具有从上向下波动减小的规律 ,波峰在黄土层 ,而波谷在古土壤层 ,也即黄土的孔隙度大于古土壤。黄土主要由粉砂、粘粒构成 ,并且黄土的粒度比古土壤要粗一些。黄土的孔隙度与黄土的颗粒组成具有相关关系 。
According to the real materials of loess layer porosity and its particulate component asertained by measuring, it is primarily known that the porosity of loess from the upper to bottom has the feature of undulate reduction The high number is in loess layers, but the low number is in paleosoils layers ,the porosity of loess is bigger than that of paleosoils Loess is mainly composed of silt and clay The size of loess is much thicker than that of paleosoils The mainfactor of the porosity is the particulate size [
