基于嘉善县基本农田质量调查和嘉善县富硒土地资源专项调查中高密度的土壤硒数据及其它测试指标，对浙北嘉善表层土壤硒的含量、分布及影响因素进行了初步研究。分析结果显示，嘉善土壤总量硒平均值为0．33mg／kg，在干窑——姚庄一带存在约57km^2的富硒土壤（Se≥0．40mg／kg）；不同土属硒含量差别不大；硒在土壤剖面中分布的总体趋势是硒在表土层聚集；嘉善富硒土壤以有机结合态和腐植酸态两种形态为主，残渣态也占有一定比例。结合全量硒与有机碳的相关性分析和富硒土壤的硒形态分析等结果，本研究认为高硒背景与有机质吸附对嘉善富硒土壤的形成起到了关键作用，改变了嘉善缺硒的认识。

Based on high density data of selenium and other indicators in soil of Jiashan Area, northern Zhejiang Province, which came from the Jiashan County based quality surver and Jiashan County selenium-rich land resource survey, the content, distribution and impactors of Se in soil have been discussed in this article. The results show that the average total selenium Jiashan soil is 0.33mg/kg, and about 57km2 of selenium-rich （Se≥ 0.40mg/kg） soil have been found. Different type soil has the similar content of selenium, and the selenium tend to enrich in the surface soil in soil profiles. Organic combination state and humic acid state are two main combination patterns in selenium of Se-rich area, and debris state also plays a certain percentage. The related analysis between total amount of selenium and organic carbon, together with the morphological analysis of selenium and other data, the study conclude that the high selenium background combine with organic matter adsorption play a key role in the formation of Jiashan Se-rich soil. So the results chanqe the attitude that Se-pool in Jiashan.
