摘　　要：通过实地采样和实验测定,运用统计特征值对位于焉耆盆地西北部的和静县的盐渍化化学特征进行分析,探讨了和静县土壤含盐量、盐分化学组成及空间分布特征。结果表明:(1)荒地土壤的含盐量远大于农田区和林区土壤;(2)区内约65%土地处于强盐渍化或者盐土状态;(3)盐渍化类型主要为氯化物—硫酸盐型盐渍化。该区内土壤盐渍化是自然和人为活动共同作用的结果。In this paper,some parts of Hejing county are chosen as the study areas.Accordingly,field investigation and tests are taken.Based on the analysis of the chemical composition of the salt-affected soil and statistical analysis of its spatial distribution,the results show that：（1） Soil salinity is greater in natural areas than in forest areas and farming areas;（2） About 65.58% of the area is heavily salinized and saltier.（3） The main salt type involved in soil salinization is chlorinate-sulfate.The salinization in this area is the results of the co-activity of nature and human being.
