原始语种摘要: To clarify the contribution of different component of selenium is the basis for evaluation of the sustainable development and utilization of selenium-rich soil. Xiuzhou district, where the soil is rich in selenium, was chosen as the study area, and its soil selenium content was qualitatively separated as the natural background component and the exogenous component through cross-validation of integrated geo-analysis and multivariate statistics. Subsequently, the contribution rate of the different component of the selenium content was separated quantitatively using frequency distribution functions. The results showed that the natural background component accounted for 90% in the soil selenium content and the exogenous component accounted for 10%, which indicated that the land sources rich...
