摘　　要：以3—5月份晋北重盐碱地多年生柽柳改良后的人工林地为研究对象,对试验地柽柳改良后盐碱地土壤的电导率、含水率、p H值、土壤金属元素等进行研究,探索其变化情况。结果表明,在3—5月份的柽柳人工林地,随着土层深度的加深,土壤的含水率、电导率都有所上升,p H值下降,有效元素Cu,Fe的含量增加;随着离植株距离的变化,离植株越远,含水量逐渐减少,p H值也越大,越来越呈现强碱性。说明种植柽柳对改良应县土壤重盐碱方面有效果,其土壤盐碱性明显低于没有种植柽柳的地块。The article took the improved artificial forest which planted perennial Tamarix chinensis between March to May as the research object in saline alkali land in north Sbanxi. Through the method of field trials and indoor-tests combination, it studied electrical conductivity, moisture content, the pH value and metal elements which had improved, to explore the change of them. The results showed that with the deepening of soil depth, electrical conductivity and moisture content rose, the pH value decreased, the metal element con-tents of Cu, Fe increased between March to May. Along with the change of plant distance the farther away from the plant, the moisture content gradually decreased, the pH value increased, the soil alkaline got stronger. It indicated that planting Tamarix chinensis Lour had a positive effect on the improvement of saline soil, its soil salinization was obviously lower than the bock which had no Tamarix chinensis Lour planting.
