中文摘要	以博斯腾湖西岸湖滨绿洲为研究区,采用Pearson相关分析与主成分分析方法,探究研究区土壤盐分特征。研究结果表明:(1)土壤表层盐分类型主要为氯化物-硫酸盐类型,其占比大于60.00%;土壤全盐量、Na~+ + K~+、Ca~(2+)、SO_4~(2-)和C1-的变异系数均大于100.00%,呈强变异性,HCO_3~-的变异系数大于90.00%,小于100.00%,呈中等变异性;Mg~(2+)在0 ~ 10与10 ~ 30 cm土壤层中分别呈强变异性与中等变异性,变异系数分别为132.85% 与93.30%;(2)土壤全盐量与主要土壤盐分离子均存在极显著正相关(P<0.01),与土壤全盐量相关性最强的土壤盐分离子为Na~+ + K~+,相关系数为0.99,相关性最低的土壤盐分离子为Mg~(2+),相关系数为0.37;(3)在不同土地利用类型中,土壤全盐量由高至低依次为未利用地(11.82 g·kg~(-1))>林地(5.98 g·kg~(-1))>草地(4.89 g·kg~(-1))>耕地(2.50 g·kg~(-1)),土壤全盐量变异系数依次为耕地>草地>林地>未利用地,变异系数最大为176.31%,变异系数最小为87.97%;(4)土壤盐分状况的特征因子为Na~+ + K~+、HCO_3~-、SO_4~(2-),其主成分综合得分模型Y=0.09(HCO_3~-)+0.30(Cl-)+0.10(SO_4~(2-))+0.17(Ca~(2+))+0.18(Mg~(2+))+0.09(Na~+ + K~+),综合得分的平均值为0.58,变异系数为122.00%,呈强变异性。
英文摘要	Taking the lakeside oasis in the western lakeside of Bosten Lake as the research area,the characteristics of soil salinity in the study area were analyzed using the Pearson correlation analysis and principal component analysis.Results of the study showed that:(1)The salt type of the surface soil was mainly chloride-sulfate,which accounted for more than 60.00%.The coefficients of variation for the soil salinity,Na~+ + K~+,Ca~(2+),SO_4~(2-),and C1-were all higher than 100.00% and were strong,and the coefficient of variation for HCO_3~-was higher than 90.00% and less than 100%,and was moderate;Mg~(2+)showed strong variability and medium variability in 0 ~ 10 cm soil layer and 10 ~ 30 cm soil layer,respectively,with the coefficient of variation of 132.85% and 93.30%,respectively;(2)There was a very significant positive correlation between the soil salinity and main ions in the soil(P<0.01).The soil salinity showed the strongest correlation for Na~+ + K~+ with the correlation coefficient of 0.99,whereas the soil salinity showed the lowest correlation for Mg~(2+)with the correlation coefficient of 0.37.(3)Among of the different land use types,the soil salinity was ranked as:the unused land(11.82 g·kg~(-1))>forest land(5.98 g·kg~(-1))>grassland(4.89 g·kg~(-1))>cultivated land(2.50 g·kg~(-1)),the coefficient of variation of the soil salinity was ranked as:cultivated land>grass land>forest land>unused land,the maximum value of the coefficient of variation was 176.31%,whereas the minimum value of was 87.97%.(4)The characteristic factors of soil salinity were Na~+ + K~+,HCO_3~-,and SO_4~(2-),the integrated score model of principal component was Y=0.09(HCO_3~-)+0.30(Cl-)+0.10(SO_4~(2-))+0.17(Ca~(2+))+0.18(Mg~(2+))+0.09(Na~+ + K~+),the average score of the composite score was 0.58,and the coefficient of variation was 122.00%,which belonged to the strong variability.
