通过野外调查，实地测点以及土壤采样分析，以开都河流域下游绿洲为研究区，利用SPSS与DPS等软件对盐分与土壤质地进行ANOVA和多重比较分析。研究结果表明：（1）土壤是以粉粒为主的质地组成。粉粒百分含量分别为0～10 cm层62．65％，10～30 cm层60．31％，30～50 cm层55．93％；0～10 cm、10～30 cm与30～50 cm表层土壤中盐分离子的均值呈现SO42－＞CL－＞Mg2＋＞Ca2＋。（2）四种土地利用类型各粒级机械组成变异系数范围分别为林地8％～62％、耕地4％～37％、园地2％～40％、未利用地15％～52％。变异系数较高；四种土地利用类型总盐的均值从高到低依次为未利用地、耕地、园地和林地。（3）不同土地利用类型粉粒差异明显，均达到显著性水平（ P＜0．05）。（4）土壤粘粒与HCO3－、Cl－、SO42－呈显著性相关（ P＜0．05）；粉粒与HCO3－离子含量呈极显著相关（ P＜0．01）。

Through field investigation ,field measurement and sampling analysis ,using SPSS and DPS software , ANOVA and multiple comparison analysis were made of salinity and soil texture in the irrigation areas of the lower reaches of Kaidu River .The results showed that the silt content of 0~10 cm layer was 62 .65% ,that of 10~30 cm layer was 60 .31% ,and that of 30~50 cm layer was 55 .93% .The mean salt ions in the surface soil of 0~10 cm ,10~30 cm and 30~50 cm was SO42 - >CL- >Mg2+ >Ca2+ .The different particle fractions of mechanical composition range of the coefficients of variation were 8% ~62% in forest land ,4% ~37% in cultivated land ,2% ~40% in garden land , and 15% ~52% in unused land .The coefficient of variation was high and total salt mean value of four land use types from high to low were respectively :unused land ,cultivated land ,garden land and forest land .Powder particles in differ-ent land use types were obviously different ,and all layers were significant .Soil clay particle was significantly related to HCO3 - ,Cl- and SO42 -( P<0 .05) .Soil powder was positively correlated to HCO3 -( P<0 .01) .
