摘要
淮北平原第四系地下水丰富,是区域内主要的生活、生产水资源之一。淮北平原土壤类型主要是钙质结核土和黄泛冲积物形成的新近沉积粉土,土壤母质均富含碳酸钙和氟。文章研究了钙质结核土及高氟水的区域分布;在分别探讨钙质结核土和高氟地下水成因的基础上,从土层性质、气候、水文地质等方面探讨了两者在形成过程中的关系;分析了F-与K+、Na+、Ca2+的相关关系,从而探讨了钙质结核土对高氟地下水形成的促进作用。
The groundwater in Quaternary System is rich in Huaibei Plain,and it is the mostly important resource of life and production in this area.Huaibei Plain agrotype is newly-aggraded silt,which is mostly formed by calcareous concretion soil on superficial layer soil,and the parent soil material is rich in calcium carbonate and fluorine.This paper studies the areas of distribution of calcareous concretion soil and high-fluorine groundwater.Based on the analysis of respective causes of calcareous concretion soil and high-fluorine groundwater,the relationship between them in their formation process is explored from aspects of soil properties,climate,hydrogeology,and so on.The relationship between F-and K＋,Na＋,Ca2＋ is analyzed,which indicates that calcareous concretion soil promotes the formation of high-fluorine groundwater.
