以开都河入湖口为研究区,通过野外土壤调查和采样结合室内实验分析,运用描述性统计学方法分析都河入湖口土壤盐分特征。结果表明:盐分在垂直方向上的变异强度由强趋弱;Ca~(2+)+Mg~(2+)在土壤各层中均呈显著正相关(P<0.01)、Ca~(2+)+Mg~(2+)和SO_4~(2-)呈显著正相关,在0~10cm,CO_3~(2-)和HCO_3~-显著正相关;开都河入湖口土壤盐分表现为上部盐分含量高,中部盐分含量较高、下部盐分含量小的特点。 Taking the Kaidu River into the lake as the research area, through the field soil survey and sampling combined with the laboratory experimental analysis, the descriptive statistics method was used to analyze the soil salinity characteristics of the Du River into the lake. The results showed that the intensity of salt variation in the vertical direction was strongly weakened; the Ca ~ (2 +) + Mg ~ (2+) was positively correlated with each other (P <0.01) ) + Mg ~ (2+) and SO_4 ~ (2-) were positively correlated with each other, while there was a significant positive correlation between 0 ~ 10cm, CO_3 ~ (2-) and HCO_3 ~ High salt content, high salt content in the middle, lower salt content.
