中文摘要	应用地统计学方法对于田绿洲典型区域土壤盐分空间分异规律进行了研究。结果表明,于田绿洲土壤盐渍化严重并表现出表聚现象。由于人类活动干扰,表层土壤盐分变幅最大;05cm土层土壤盐分表现出强烈的空间相关性,530cm土层次之,3070cm土层土壤盐分的空间相关性很弱。水平方向上,030cm土层中土壤盐分从东向西先增大,后减小,再增大,再减小;3070cm土层中土壤盐分从东向西逐渐减小;研究区南北两侧土壤盐分含量高,中部盐分含量低。垂直方向上,盐碱地和高、中密度草地土壤盐分含量较高,呈现出自上而下逐渐减小的分布趋势。其中盐碱地土壤盐分含量最高,高密度草地土壤盐分的垂直变化幅度大于中密度草地,低密度草地和农田土壤盐分含量较低,且垂直变化不大。不同地形和土地利用带来的土壤水分运动差异,是绿洲土壤盐分空间分异的主导因素。
英文摘要	Spatial heterogeneity of soil salinity in the typical area of Yutian oasis was analyzed by using geostatistics.Results indicated that soil salinization in Yutian oasis was severe and soil salinity accumulated in surface soil layer.The variational amplitude of soil salinity in surface soil layer was the highest because of the disturbance of human activities.The spatial correlation of soil salinity in the 05 cm soil layer was strong;in the 530 cm soil layer,in the second place;and in the 3070 cm soil layer,relatively low.In the horizontal direction from east to west,soil salinity in the 030 cm soil layer manifests an increase and decrease trend,while soil salinity in the 3070 cm soil layer gradually declined.Soil salinity was high in the northern and southern parts of the study area and low in the interior part.In vertical direction,soil salinities in saline land,highly coved grassland and medially coved grassland were relatively high and gradually decreased from soil surface to lower soil layer.Soil salinity in saline land was the highest,the variational amplitude of soil salinity in highly coved grassland was greater than that in medially coved grassland,soil salinities in farmland and lowly coved grassland were relatively lower with low variational amplitudes.The main factor for the spatial heterogeneity of soil salinity in the oasis was the difference of soil and water movement in different landforms and land uses.
