安徽省土壤中氟分布的研究

安徽省２２９ 个土壤剖面土壤总氟和土壤水溶性氟含量测定数据表明，５ 个地理分区之间土壤总氟差异不大，Ａ 层和Ｃ层均值分别为５２２ ｍ ｇ／ｋｇ 和６０４ ｍ ｇ／ｋｇ；而土壤水溶性氟在不同地区之间的差异显著，其分布规律是自北向南降低：淮北平原＞ 江淮丘陵＞ 沿江平原＞ 皖南山区＞ 大别山区。土壤总氟与土壤水溶性氟无相关性。

Study on the Distribution of Fluorine in Soils of Anhui Province.

The results of 229 analyses on soil profiles, soil total fluorine and soil water soluble fluorine showed that there was no large difference on soil total fluorine among the 5 geographical areas of Anhui Province. The mean contents of soil total fluorine in A horizon and C horizon of the 5 areas were 522 mg/kg and 604 mg/kg, respectively. However, significant differences were existing in the contents of water soluble fluorine in soils of the different areas. An obvious decreasing tendency from north to south of the province on soil water soluble fluorine was observed. The results also showed that there was no correlation between the contents of soil total fluorine and soil water soluble fluorine.
