摘　　要：对宁夏银北地区典型试验区在春夏季的盐渍土水盐动态变化进行试验研究。结果表明,浅层土壤水平断面土壤含水率呈现出东北高西南较低的曲面形态,土壤全盐量动态变化与之相反,监测期内土壤水盐动态变化剧烈,主要受当地降雨、蒸发和地下水埋深以及地下水矿化度的影响。There is a experimentally study on dynamic movement of water and salt in typical test area of Yinbei region of Ningxia province. The soil moisture content and salt content are surveyed and evaluated by equipment which is time delay reflectometry. The results show that the horizontal section of soil moisture is represented a surface morphology which was low in southwest and high in northeast, while dynamic changes of salt content in saline soil has the opposite surface morphology with soil moisture. Dynamic monitoring of soil water and salt is frequent activites during the period of spring and summer. Those contents had more affection to local rainfall, evaporation and groundwater impacts and groundwater depth salinity.
