安徽庐江矾山地区土地质量地球化学评估及富硒特征研究

GEOCHEMICAL EVALUATION OF THE LAND QUALITY AND SELENIUM ENRICHMENT FEATURES IN THE FANSHAN AREA,LUJIANG COUNTY,ANHUI PROVINCE

文章基于安徽庐江矾山地区土壤数据,对土壤硒的地球化学特征进行研究,并开展了土地质量地球化学评估。土壤硒属于明显富集强分异型,主要与地质背景有关。研究区以富硒、足硒土壤为主,二者面积为157.80km^(2),占总面积的98.07%。研究区土地质量整体优良,优质和良好土壤面积为128.57km^(2),占总面积的79.91%;中等土壤面积为30.81km^(2),占总面积的19.15%。

Based on the soil data of the Fanshan area in Lujiang County,Anhui Province,this paper studies the geochemical features of selenium in the soil and carries out geochemical evaluation of the land quality.The results show that the soil selenium is obviously enriched and strongly differentiated,which is mainly related to geological background.In the study area,selenium-rich and selenium-sufficient soils are dominant,covering an area of 157.80 km^(2),accounting for 98.07%of the total area.The overall land quality in the study area was excellent.The area of high quality and good soil was 128.57 km^(2),accounting for 79.91%of the total area,and the moderate soil 30.81 km^(2),19.15%.
