摘　　要：以伊犁河谷察布查尔县新垦区为研究区域,运用传统统计学与地统计结合方法对研究区中5种典型农田的土壤盐分空间特征进行研究。结果表明:5种农田土壤中玉米地、苜蓿地盐分均值含量差异性较大,5种农田土壤的变异系数均为中等变异;随着土层深度的不断增加,食葵地、苜蓿地盐分有明显增大趋势,分别上升到1.043%、1.509%;伊犁河谷新垦绿洲盐渍化程度以轻度、中度为主,并且不同农田的土壤盐分空间具有差异性。该研究为准确掌握和改善伊犁河谷新垦绿洲内型农田盐渍化程度提供科学支撑。This paper in the new reclamation area of Ili River Valley of Qapqal County as the study area,using traditional statistics and geostatistics method to study area in 5 kinds of typical farmland spatial characteristics of soil salinity were studied.Results showed that 5 kinds of farmland soil in corn,alfalfa average salinity content differencegreatly,five soil coefficient of variation were moderate variability;with the increase of soil depth,the salt content inthe sunflower field and alfalfa field increased to 1.043% and 1.509% respectively;the salinization degree of the newly reclaimed oasis in the Ili valley is mainly mild and moderate,and the spatial variability of soil salinity in differentfields. The degree of salinization of the typical farmland in the new oasis of yili river valley is mastered,and the scientific support is provided to improve the salinization degree of the farmland in the new oasis of yili valley.
