中文摘要	采用常规统计学和典范对应分析法,分析于田绿洲2012年春季土壤剖面(0~10、10~20、20~40、40~60、60 ~80、80~100 cm)的含盐量、电导率、pH值、矿化度、七大盐分离子的空间分布特征。结果表明:春季土壤含盐量、电导率、pH值和矿化度都随着土壤深度的增加而逐渐减小,土壤中Na~+和Cl~-在各土层占有主要优势,随着土壤深度的增加,各个盐分指标变异系数减小,土壤介质趋于均匀,性质趋于稳定;利用典范对应分析方法发现各个土层中Na~+ Cl~-、Ca~(2+)、K+始终保持较好的相关性,且主要呈现正相关关系。
英文摘要	Study on spatial distribution of soil salinity is important for guiding agricultural production. In the Yutian Oasis, the soil saline-alkalization problem is quite severe. In this paper, the salt content, ion components, electrical conductivity, mineralization degree and pH value were investigated with conventional statistics and canonical correspondence analysis methods for testing the spatial variability of soil salinity. The results indicated that in this oasis soil salinity profile belonged to the top enrichment, and was mainly the sulfate chlorination; the soil was slight to moderate in alkalization. Soil salinity, electrical conductivity, pH value and mineralization degree increased with increasing soil depth; in the soil, Na~+ and Cl~- played an essential advantage, as soil depth increased, the the coefficient of variation decreased, the soil media became more uniform and more stable; the canonical correspondence analysis showed that Na~+ and Cl~-, Ca~(2+) and K~+ were well correlated in all soil layers, and showed mainly positive correlation relationship. This study could provide lots of scientific support for soil salinity treatment and improvement, agricultural planning and adjustment, and irrigation and drainage engineering planning in the future.
