| 摘 要： | 根据2009年伊犁河灌区土壤临测和取样分析资料,运用半方差函数与克里格插值法,对伊犁河灌区灌溉期与非灌溉期土壤盐分含量变异特征进行了分析.结果表明:研究区耕层土壤53.68%样地呈非盐渍化土壤,18.38%为轻度盐渍化,13.97%为中度盐渍化,8.82%为重度盐渍化,5.15%为盐士.土壤盐渍化类型主要为硫酸盐渍土为...

| Abstract: | According to monitoring and sample analysis of soil salinity in Eli River irrigated area,we analyzed the spatio-temporal variation of soil salinity in Eli River irrigated area,western Tianshan mountains,China,using variogram model and Kriging.Results of the study showed that 53.68% of root soil layer is non-salinized while 20.59% of the land slightly salinized,13.97% moderately salinized,8.09% strongly salinized and 3.67% saline soil.The type of soil salinization is mainly sulphate saline soil.Anions are ma... |
