摘要/Abstract

摘要： 为研究吉林西部乾安大布苏湖畔“泥林”地区土样分散性特征，在采样地区选取两个采样点进行垂直深度采样并作分散性鉴定.在对土样进行粒度分析和物理化学性质分析的基础上，采用针孔试验等实验方法进行土样分散性的判定研究.实验结果表明:地表以下0~1m范围，土样以粉粒为主，易溶盐总量大于0.3%，两个采样点含盐量随深度的增加而呈现不同变化特征.采样地区浅层的土样分散性较高，1号采样点土体分散性随着取样深度增大分散性呈现减小趋势；2号采样点的土体均判定为分散性土，分散性变化小.

Abstract: To study the properties of soil samples collected from Qian’an soil forest， two sampling points were chosen for vertical sampling and the dispersion identification was made. Based on the study of particle-size analysis and physicochemical analysis， the dispersion of the soil was determined by different identification methods， including pinhole test， crumb test and double-hydrometer test. The results showed that within the depth range from 0 to 1m， the silt particles account for a large proportion of the soil samples. The total soluble salt accounts for approximately 0.3% or above. The two sampling points display different change rules of the soluble salt. It is obvious that the shallow soils of these two sampling points are highly dispersive. At the first sampling point， the dispersion degree decreases with the increase of the depth， while it is not obvious at the second sampling point.

Key words: saline soil, physicochemical property, dispersion, pinhole test, crumb test
