中文摘要	为详细分析流动沙漠咸水滴灌人工绿地土壤盐分的空间分异特征,采用经典统计学和地统学结合的方法,对塔中作业区表层(05cm)和亚表层(2040cm)土壤盐分及各组成离子含量的空间变异性进行系统研究. 结果表明:塔中人工绿地表层盐分含量远高于亚表层,呈现强烈的表聚性;半方差函数分析得出表层盐分及离子组成具有极强的空间自相关性和空间异质性,主要受结构性因素(地形、母质、气候等)影响,盐分及组成离子与海拔呈负相关关系,说明人工绿地盐分的空间分布具有海拔梯度性;亚表层盐分的空间分异尺度和格局更具趋同性,随机性因素(灌溉、地下水、植被等)作用显著. Kriging空间插值及空间统计分析表明:在整个纵向沙垄断面,有64.9%的表层土壤发生盐渍化作用,主要为弱盐渍化类型,垄间区较迎风坡和背风坡盐渍化危害更为严重
英文摘要	The objective of this study was to explore the spatial distribution of soil salinity in artificial green land of mobile desert. Classical statistical coupling with geo- statistical theory was used to characterize the spatial variability of soil salinity in topsoil (0 - 5 cm) and subsoil (20 - 40 cm), respectively. The results showed that the topsoil content of soil salinity and its ions was more than that of subsoil. The result of semi- variance analysis showed that the soil salinity and its ions in topsoil had strong spatial variability and spatial autocorrelation, and their spatial variability was primarily result from structural factors, and the negative correlation was existed between soil salinity and elevation, which indicates that the spatial distribution of soil salinity has the vertical gradient. The spatial distribution of subsoil salinity tended to homogeneity, which was primarily result from random factors. The results of Kriging interpolation maps and spatial analysis showed that the area of artificial green land affected by salinization in topsoil accounted for 64.9%, and the main style was light salinization in them. The degree of soil salinization in interdune was more serious than that in windward and leeward slope of complex ridges
