摘要/Abstract

摘要： 为探讨贵州省普安县耕地土壤硒元素地球化学特征及影响因素，以该县1∶5万耕地质量地球化学调查评价成果为基础，利用参数统计、绘制等值线图、相关性分析等方法，总结该县耕地土壤中硒元素的地球化学特征，并研究硒的影响因素。研究结果发现，该县富硒耕地资源丰富，硒元素分布主要受成土母质影响，同时，丰富的有机质以及酸性土壤的广泛分布，亦是造成硒元素富集的重要原因。

Abstract: In order to discuss the geochemical characteristics and influencing factors of selenium in cultivated soil of Pu′an County,Guizhou Province,based on the results of the geochemical survey and evaluation of 1∶50 000 farmland quality in the county,by means of parameter statistics,isoline drawing,correlation analysis and other methods,summarized the geochemical characteristics of selenium in the cultivated soil of this county,and research the influencing factors of selenium.The results show that the selenium rich cultivated land is rich in resources,and the distribution of selenium is mainly affected by the parent material.At the same time,the extensive distribution of rich organic matter and acid soil is also an important reason for selenium enrichment.
