松嫩平原拜泉地区50米以浅地表基质化学元素垂向特征及含量等级
Vertical characteristics and content grade of chemical elements in the ground substrate(0-50 m deep)of Baiquan area,Songnen Plain
摘要
Abstract
By analyzing the soil substrate samples in the depth of 0-50 m from borehole BQZK05 in Baiquan County,Heilongjiang Province,the study ascertains the vertical distribution characteristics of major,mineral,beneficial and toxic elements,and evaluates the quality of some chemical elements in the soil.The results show that the CaO content belongs to Grade III(medium),MgO content Grade II(rich),and Fe2O3 content Grade II(rich)in terms of major elements.Of the mineral elements,Fe content belongs to Grade IV(deficient),Mn content Grade III(medium),and S content Grade I(abundent).In terms of beneficial elements,the Se content belongs to moderate grade,I content the deficient grade,F content the high grade,and K content the middle-high grade.The content of toxic elements is much lower than the risk screening value and control value of agricultural land soil pollution,and the soil environment quality is first-class clean.关键词
