摘  要：
采用网格法对陕西富平国土资源部退化及未利用地土地工程整治重点实验室中试基地对流-弥散盐碱地试验田进行采样,分别测定0~10、10~20、20~30、30~50、50~70、70~100、100~150、150~200 cm的土壤p H及电导率。研究了蓄水条件下土壤p H与电导率的空间分布特征及二者之间的相关关系,结果表明:在蓄水条件下,土壤p H和电导率均随着土壤深度的增加而增加;土壤p H与电导率均在20~50 cm土层处具有最高变异系数;土壤p H与电导率呈极显著正相关关系。通过掌握蓄水条件下土壤p H与电导率的空间分布特征及相关关系可以为盐碱地地区盐渍化的防治和盐碱地的合理利用提供依据。

摘  要：
In this study,the grid method is used to sample the convection dispersion test field in testing base of Key Laboratory of Degraded and Unused Land Remediation Engineering,Ministry of Land and Resources,in Fuping City,Shaanxi province. The p H and conductivity in the depth of 0 ~ 10,10 ~ 20,20 ~ 30,30 ~ 50,50 ~ 70,70 ~ 100,100 ~ 150,150 ~ 200 cm are respectively tested. The spatial distribution characteristics of soil p H and conductivity and the correlation between them are studied under the condition of water storage. The results show that under the condition of water storage,soil p H and conductivity increases with the increase of soil depth; both the p H and conductivity of soil have the highest coefficient of variation at the 20 ~ 50 cm depth soil layer. The p H is positively correlated with conductivity. The study results can provide basis for salinization prevention and reasonable use of saline-alkali land in salty soil area.
