安徽省砀山县土壤元素背景值特征分析
Analysis of background levels of soil elements in Dangshan County,Anhui Province
摘要
Abstract
Based on analysis of 1∶50000 geochemical survey and evaluation data on land quality in Dangshan County,Anhui Province,this paper makes statistics of geochemical parameters of 27 indicators of 6444 surface soil samples,determines the background levels of soil elements in Dangshan,and analyzes the differences in the levels between Dangshan and northern Anhui,indicating that the background level of soil nitrogen in Dangshan is significantly lower than that in northern Anhui,and the levels of P,Na2O and CaO are significantly higher than those in northern Anhui,the levels of 23 indicators such as Cl,MgO and SiO2 in Dangshan County are equivalent to those in northern Anhui.Finally,the characteristics and influencing factors of element associations are studied through the factor analysis of 27 indicators of the surface soils.The results of this study provide a scientific basis for the sustainable development and utilization of soil resources,the adjustment of agricultural planting structure and the formulation of high-efficiency micro element fertilizer in Dangshan.关键词
