  • 摘要: 为识别巢湖流域污染物的特征、来源及其沉积物有机磷各形态分布与富营养化的关系，测定了7条巢湖入湖河流沉积物中有机磷各形态的含量，分析不同污染类型入湖河流沉积物中有机磷各形态分布的差异及与其他因素间的相关性。研究发现，不同污染类型入湖河流沉积物中水土保持控制型河流沉积物中有机磷各组分的相对含量顺序为残渣态Po >富里酸-Po >HCl-Po >胡敏酸-Po >NaHCO3-Po，平均的相对比例为7.5：3.1：1.9：1.5：1.0，而城市污染控制型和面源污染控制型河流沉积物中有机磷各组分的相对含量顺序恰好相同，面源污染控制型河流沉积物Po各形态含量低于城市污染控制型和水土保持控制型河流。中活性Po和OM、TP、Pi、Po、TN、NaHCO3-Pi、NaOH-Pi呈正相关，非活性Po与Po、NaOH-Pi呈显著正相关关系，反映了中活性Po很容易转化为生物可利用磷和非活性Po，且非活性Po仍然具有潜在的生物活性。
    Abstract: In order to identify the characteristics and sources of pollutants in Lake Chaohu Basin, as well as the relationship between eutrophication and distribution of organic phosphorus forms, the contents of various forms of organic phosphorus in sediments from seven inflow rivers of Lake Chaohu were determined, and analyses were given respectively on the distribution differences of various forms of organic phosphorus in the sediments of inflow rivers with different pollution types, and the relationship with other factors. The results show that the relative content order of Po fractions is residual Po>fulvic acid-Po >HCl-Po >humic acid-Po >NaHCO3-Po in sediments of soil and water conservation river, with the relative proportion of average: 7.5:3.1:1.9:1.5:1.0. The relative content order of Po fractions in sediments of urban pollution and non-point source pollution rivers is nearly identical, and the content of Po fractions in non-point source pollution rivers is lower than urban pollution and soil and water conservation rivers. The study finds that the middle labile Po is correlated with OM,TP,Pi,Po,TN,NaHCO3-Pi and NaOH-Pi. Furthermore, nonlabile Po is significantly correlated with Po and NaOH-Pi. They reflect that the middle nonlabile Po may easily convert into bioavailable phosphorus and nonlabile Po, while nonlabile Po still has the potential of bioavailable.

摘要: 为识别巢湖流域污染物的特征、来源及其沉积物有机磷各形态分布与富营养化的关系，测定了7条巢湖入湖河流沉积物中有机磷各形态的含量，分析不同污染类型入湖河流沉积物中有机磷各形态分布的差异及与其他因素间的相关性。研究发现，不同污染类型入湖河流沉积物中水土保持控制型河流沉积物中有机磷各组分的相对含量顺序为残渣态Po >富里酸-Po >HCl-Po >胡敏酸-Po >NaHCO3-Po，平均的相对比例为7.5：3.1：1.9：1.5：1.0，而城市污染控制型和面源污染控制型河流沉积物中有机磷各组分的相对含量顺序恰好相同，面源污染控制型河流沉积物Po各形态含量低于城市污染控制型和水土保持控制型河流。中活性Po和OM、TP、Pi、Po、TN、NaHCO3-Pi、NaOH-Pi呈正相关，非活性Po与Po、NaOH-Pi呈显著正相关关系，反映了中活性Po很容易转化为生物可利用磷和非活性Po，且非活性Po仍然具有潜在的生物活性。
