摘要:
以新疆博斯腾湖西岸湖滨带为研究区,利用相关分析和主成分分析法对土壤离子盐分特征进行研究,结果表明:(1)0~10 cm土层中平均盐分含量为5.413 g·kg-1,占整个土层盐分含量的42.5%,土壤盐分表聚现象明显;(2)垂直方向上土壤含盐量在 0~10 cm土层变异系数为1.012,属于强变异程度,其它深度土壤盐分含量均属于中等变异;(3)通过相关性分析,该区域土壤盐分组成以硫酸盐和氯化物为主.在0~10 cm土层中SO2-4和Na++K+的相关系数为0.955; 在10~50 cm土层中CL-与Na++K+相关系数为0.970;(4)通过对影响土壤盐渍化主导因子的主成分分析得出,土壤含盐量、Na++K+ 、SO2-4及CL-是表征博斯腾湖西岸湖滨带土壤盐渍化主要特征因子.
Abstract:
Using correlation analysis and principal component analysis, in combination with the regional investigation of soil properties, characteristics of the soil salinity of the western lakeside of Boston Lake was studied. The results show, 1)at the soil depth of 0~10 cm, the average soil salinity content was 5.413, accounted for 42.5% of the soil salt content, the phenomenon of salt accumulated in the soil surface was strong; 2)in the vertical direction, the variation coefficient of salt content in 0-10cm was1.012 with strong degree of variation, other depth soil salt contents are belonged to medium variation; 3)through the correlation analysis, the composition of soil salt is given priority to sulfate and chloride. The correlation between SO2-4 and Na++K+ was 0.955. while the coefficient between CL- and Na++K+ was 0.970 in 10-50 cm; and 4)based on the influence of soil salinization, using principal component to analyze the dominant factor. The conclusion is that the soil salinity, Na++K+, SO2-4 and CLare the key factors to characterize soil salinization of the western lakeside of Boston Lake.
