| 摘 要： | 取两个池塘底泥和上覆水进行室内模拟水体小环境试验,设对照组及5个处理组,进行4个月培养,采用连续分组法测定底泥中无机磷形态及其含量,分析底泥潜在无机磷变化及其与上覆水体可溶性活性磷(DRP)含量的关系.结果表明,池塘底泥中无机磷各形态含量依次为钙10结合磷(Ca10-P)＞闭蓄态磷(O-P)＞铝结合磷(Al-P)＞铁结合磷(Fe-P)＞钙8结合磷(Ca8-P)＞钙2结合磷(Ca2-P);4个月后两池塘底泥中的Ca2-P和Fe-P增加,Ca10-P、O-P、Al-P减少;上覆水体中DRP含量与O-P、Ca2-P、Ca8-P和Ca10-P之间呈显著正相关;底泥中无机磷各形态对上覆水体中DRP含量的直接影响大小依次为O-P＞Ca8-P＞Ca2-P＞Ca10-P＞Fe-P＞Al-P;5个处理组上覆水体中DRP含量都低于对照组;沸石与芽孢杆菌组合处理的上覆水体中DRP含量最低,表明采用沸石与芽孢杆菌组合进行底泥处理是控制上覆水中DRP含量的有效方法.

| Abstract: | The sediments and overlying water sampled from two different ponds A and B were placed in glass aquaria and cultured for 4 months under indoor environment to simulate pond environment, and six treatments were designed in the experiment to compare their effects on the forms of P and the content of dissolved reactive phosphorus (DRP). The amounts and forms of inorganic phosphorus (IP) in sediments were evaluated using a sequential chemical extraction, the relationship of potentially mobile P in sediments and ... |
