摘要

采用GPS定位系统

于2011年10月在柴河小流域采集表层土样50个

结合传统统计学方法和ArcGIS地统计学法分析了柴河小流域表层土壤盐分及钙镁离子含量的空间变异特征。结果表明

研究区表层土壤盐分及水溶性钙镁离子呈对数正态分布;柴河流域表层土壤盐分与水溶性钙镁离子、全氮、全磷及有机质呈显著正相关关系;结合柴河小流域高程南高北低的趋势

土壤盐分和土壤钙离子在低洼处均较高

表现出较强的迁移性。

Abstract

Fifty soil samples were collected in Chaihe basin in October 2011

and the sampling locations were recorded by GPS.Traditional statistics and geostatistics based on ArcGIS were used to analyze the spatial distribution of soil salt and water-soluble Ca2+ and Mg2+.Results from traditional statistical analysis showed that surface soil salt

water-soluble Ca2+ and Mg2+ were exhibited as logarithmic normal distribution within the study area.The content of water-soluble Ca2+ and Mg2+

total soil organic matter

total nitrogen and total phosphorus has significant positive correlation with soil salt.The soil salinity and soil calcium ions showed strong mobility as there were more in the low-lying place.
