调查研究了伊犁州土壤中硒资源的分布特征，为该地区富硒农产品的开发提供理论指导。用原子荧光光度法测定了新疆伊犁州6个县158个农田土壤样品的全硒含量，并运用统计分析方法对伊犁州土壤硒资源的分布特征及与土壤理化性质的关系进行了分析。结果表明，伊犁州6个县土壤中全硒含量范围为0.14~2.75 mg·kg-1，几何均值为0.33 mg·kg-1，其中昭苏县土壤全硒含量均值最高，巩留县最低。所检测的土壤样品中有2.38%属于少硒土壤，78.57%属于足硒土壤（0.175~0.45 mg·kg-1），19.05%属于高硒土壤（0.45~3.00 mg·kg-1）。统计分析的结果表明，有机质、速效钾、碱解氮与全硒含量呈极显著正相关（P<0.01），pH值与硒含量成显著负相关（P<0.01）。伊犁州土壤中硒的含量水平偏高，可以优先考虑富硒农业的开发建设。

The aim of this work was mainly to study the distributions of selenium(Se)resource in soils to provide basic information for the exploitation of Se-enriched agricultural products in Ili District, Xinjiang Uygur Autonomous Region. Based on the analysis data of total Se content from 158 soil samples in six counties, the distribution characteristics of Se and the correlation with soil physicochemical properties were analyzed with the statistic method. The results indicated that the geometric mean value of Se content in the soils of Ili district was 0.33 mg·kg-1, ranged from 0.14 mg·kg-1 to 2.75 mg·kg-1. The soil in Zhaosu county had the highest average, and Gongliu county had the lowest. The statistics analysis showed that the percentage of low Se soil, full Se soil(0.17~0.45 mg·kg-1)and high selenium soil(0.45~3.00 mg·kg-1) was 2.38%, 78.57% and 19.05%, respectively. The content of total Se was significantly positive correlated with organic matter, available potassium and available nitrogen(P<0.01), while pH showed negative correlation with Se(P<0.01). High level of Se content in soils provided an opportunity to develop the Se-enriched agricultural products in Ili district.
