河南省商丘地区土壤地球化学特征
|
摘要
基于河南商丘地区多目标地球化学调查数据资料,在正态和对数正态检验的基础上,统计获得了土壤54种元素(指标)的地球化学基准值和背景值,查明了土壤元素指标组合、分布特征、富集贫化规律。结果表明,调查区土壤元素含量普遍低于全国土壤基准值,其中Se元素含量仅为全国的0.28倍,而Ca O含量最高,为全国的1.96倍;对比发现研究区多数元素(指标)的背景值与基准值相当,说明表生成土作用过程中这些元素的迁移重分配作用较弱,人为活动对其污染影响较小;而Corg、N、Se、Hg、P、TC等元素(指标)在表层富集,反映出较为显著的表生富集和人为污染叠加的特点。因子分析表明,风化作用、淋溶作用及农业施肥、生物地球化学循环过程是影响研究区表层土壤地球化学特征的主要因素。
Based on the Multi-Purpose Regional Geochemical data of Shangqiu area in Henan Province and on the basis of normal and logarithmic normal tests,we calculated geochemical baseline and background values of 54 elements(indicators) in soil,analyzed enrichment or dilution of main elements in soil,and discussed geochemical characteristics of elements in surface soil. Results show that compared with national values,the geochemical baseline values are generally low. The content of Se is the lowest with only 0.28 times of the national value,while CaO is the highest,which is 1.96 times that of the country. The differences between baseline and background values of most elements(indicators) are not obvious,due to slight hyper-genesis effect and human activities; however,elements including Corg,N,Se,Hg,P,TC are enriched in surface soil because of obvious anthropogenic input. The factor analysis shows that the weathering,leaching and plant rhizosphere enrichment are the main factors affecting the geochemical characteristics of surface soil in the study area.
