摘 要：
在湖北省江汉流域经济区多目标区域地球化学调查的基础上,对大量数据进行分析统计,显示江汉平原及周边丘峦存在大量富硒土壤资源。按照多目标区域地球化学调查规范中所采用的双层网格化采样模式,采取单位土壤硒量的方法,按照直线公式计算土壤硒资源量,并分别从土壤类型及成土母质的特征来分析研究。结果表明,江汉流域经济区表层(0~0.2 m)土壤硒资源量为5 314.69 t,深层(0~1.8 m)土壤硒资源量为38 764.66 t;区内两大储硒类型为灰潮土、潴育型水稻土,且土壤硒主要集中分布在第四系的成土母质类型中。

摘 要：
Large amounts of data statistics on the basis of multi-target regional geochemical survey in Jianghan River economic zone of Hubei province show there are many selenium-rich soil resources existing on Jianghan plain and the surrounding hills mountain.According to double grid sampling mode in multi-target regional geochemical survey specification,the calculation of soil selenium resource was in accordance with the linear formula of unit of soil selenium content.And the analytical investigation was respectively from soil types and the characteristics of parent material.The results show that data indicate surface(0~0.2 m) soil's selenium resource is 5 314.69 t.And deep(0~1.8 m) soil's selenium resource is 38 764.66 t.There are two kinds of soil store selenium easily which are grey alluvial soil and waterloggogenic paddy soil,and soil selenium mainly distributed in the quaternary soil parent material.
