| 摘 要： | 以潍坊北部海水入侵区域为研究区,通过实地采样获得研究区表层土壤盐分数据,利用统计分析与空间插值的方法对潍坊北部表层土壤盐分空间分布特征进行分析。结果表明:该区域土壤盐分主要离子为Na~+、Cl~-等,土壤全盐量、K~+、Na~+、Mg~(2+)、Cl~-、SO_4~(2-)呈强变异强度,Ca~(2+)和HCO_3~-属于中等变异强度。潍坊北部地区表层土壤盐分的空间分布为土壤全盐量、Na~+、K~+、Mg~(2+)、Cl~-以及SO_4~(2-)都是东北部沿海地区土壤盐分含量较高,从东北向西南呈现逐渐递减的趋势。

Analysis of Spatial Distribution Characteristic of Surface Soil Salt Content in Northern Weifang |

| Abstract: | Taking seawater intrusion region of northern Weifang as the study area,the surface soil salinity data of the study area were obtained by field sampling,and the spatial distribution characteristics of surface soil salinity in northern Weifang were analyzed by statistical analysis and spatial interpolation.The results showed that the main salt ions in soil were Na +,Cl-and so on.The soil total salt content,K+,Na +,Mg2+,Cl-,SO42-showed the strong spatial variability,and Ca2+,HCO3-showed the moderate spatial.The spatial distribution of soil salinity in northern Weifang was that soil total salt content,Na+,K+,Mg2+,Cl-,SO42-of northeastern coastal areas was higher,and gradually declined from northeast to southwest. |
