摘要

在野外GPS定点定位调查、土壤样品分析的基础上

借助Excel和ArcGIS9.3等软件

对新疆自治区喀什市岳普湖县塔吉克阿巴提镇0-30cm土层的盐离子特征、灌区土壤盐渍化现状及空间分布特征进行了分析。结果表明

0-30cm土层土壤中的离子以Cl-

SO42-

Na+

Ca2+为主Na+与Cl-呈极显著正相关关系

Abstract

On the basis of field survey

UPS location and soil analysis

a study was carried out with the Excel and ArcUIS 9.3 software to analyze salt ions

present situation and spatial characteristics of soil salinization at the Tajik Abat Town.The results showed that ions in 0-30 cm soil were dominated by Na+

Ca2+

C1-

among which there was a strong positive correlation(r=0.98)between Na+and Cl

negative correlations between HCO3- and the other six ions-

Ca2+

Mg2+

K+

C1-

SO42-);the ratio of Cl-to SO42- was much lower on cultivated land than wasteland;the ratio of Cl- to SO42+ in 0-30 cm soil was positively correlated with total salt on both cultivated land and wasteland with correlation coefficients 0.68 and 0.32

respectively.At the presentst age

chloride-sulfate salinization soil
