摘要：

[目的]对采煤塌陷区土壤中磷赋存形态以及释放规律进行研究,了解土壤磷污染特征。[方法]以淮南矿区潘一矿塌陷区为研究对象,应用分级提取的方法对塌陷区土壤中磷的赋存形态进行分析测定,采用室内柱状样模拟实验对土壤中磷释放特征进行研究。[结果](1)潘一杨庄塌陷区土壤TP的含量在103.58~489.89 mg/kg之间,平均值为248.47 mg/kg;(2)活性磷(BAP)的含量在86.94~378.24mg/kg,占TP含量的43.53%~91.12%,平均为71.1%。(3)TP累计释放量大小依次为:pH=12>pH=3>pH=6>pH=8>pH=10>pH=4。[结论]采煤塌陷区土壤中TP有极高的释磷潜力;不同pH值条件下,磷的释放强度大小为:碱性>酸性>中性。

摘要：

[Objective]This paper mainly studied the phosphorus speciation and release law in the soil of coal mining subsided area,to know the phosphorus pollution characteristics.[Methods]Phosphorus content and fractions in the soil of NO.1Panji subsided area were analyzed using sequential extraction method,and the release characteristics of phosphorus in the soil were studied using the columnar sample simulation experiment.[Results](1)Total phosphorus(TP)content in the soil varied from 103.58mg/kg to 489.89mg/kg,and the average content was 248.47mg/kg;(2)Bioavailable phosphorus(BAP)content varied from 86.94mg/kg to 378.24mg/kg,accounting for 43.53%~91.12% of TP;(3)The cumulative release quantity of TP was in the following order:pH=12>pH=3>pH=6>pH=8>pH=10>pH=4.[Conclusion]High potentiality of phosphorus release had been discovered by the research of soil in coal mining subsided area.In different pH conditions,the releasing strength of phosphorus was ranked as:alkaline>acid>neutral.
