摘　　要：针对新疆石河子150团人工胡杨林进行了夏季土壤水盐时空变化规律研究。结果表明:在时间变化上,土壤含水率主要受气温影响,随气温升高而降低;在土壤分层区间上,除表层土壤外,土壤盐分与水分具有同步变化趋势,体现了盐随水动的特点,盐水变化的相关性系数为0.98;同时,pH也随着月份的推移而表现出逐渐升高的趋势,pH与CO32-、HCO3-、Cl-、Ca2+呈现显著相关性。The space-time movement of salt and moisture in 150 regiment in shinezi artificial Populus euphratica forest soil in summer were studied.The results showed that the temperature play a main role in soil moisture,which had a same trend with the temperature,and that concerning the soil space layers,the soil salt follow the movement of soil moisture but the surface layer,which manifest the trait of salt moving with moisture.Comparing the movement of moisture and salt,the correlation coefficient was 0.98.In addition,pH increased from june to august.The CO2-3,HCO-3,Cl-and Ca2＋ had notable relevance with pH.
