摘要
通过对鄱阳湖周边厚覆盖区土壤垂深剖面的构成特点、土壤酸碱度、元素分布分配规律的分析研究,探讨了区内元素的相关组合特点及元素在深度方向上“含量稳定性拐折点”的位置,揭示了区域内土壤垂深剖面的地球化学特征与环境意义。根据数理统计原理,结合区域内土壤垂深剖面的地球化学特征和大规模生产的条件,指出区域内土壤第Ⅰ环境的合理采样深度为-150^-180cm。
Based on an analysis of structural characteristics of soil vertical profile, soil acidity-alkalinity and regularity of element distribution in thick overburden areas around the Poyang Lake, this paper has tentatively discussed characteristics of element associations and the position of 'turning point of element content stability' towards the depth, and revealed geochemical characteristics of regional soil vertical profile and their environmental significance. According to statistical principle in combination with geochemical characteristics of regional soil vertical profile and conditions for large-scale production work, it is pointed out that the rational sampling depth of regional soil No. Ⅰ environment is -150～-180 cm.
