| 摘 要： | 选取了滇池外海北部、中部和南部柱状沉积物样品,结合上覆水磷和柱状沉积物有机质数据,研究了有机质(OM)及粒径组成对沉积物释放的影响,并探讨了不同形态磷对沉积物释放的影响及贡献.结果表明:1沉积物间隙水ρ(DTP)和ρ(SRP)均与OM、沉积物黏土(4.00μm)和粉砂粒(4.00~63.00μm)含量呈显著负相关,但与砂砾(63.00μm)含量呈显著正相关,表明沉积物有机质含量的增加显著降低了其间隙水中磷的质量浓度,且黏土和粉砂粒含量的增加也会降低间隙水磷的质量浓度,抑制了沉积物磷的释放.2滇池沉积物潜在可移动磷(BD-P和NaOH-nrp)与黏粒和粉砂砾均呈显著正相关,与砂砾呈显著负相关,表明黏粒和粉砂砾可能对沉积物磷的移动能力提升,砂砾可能对沉积物磷的滞留能力提升.3在较短时间尺度内,外海北部沉积物磷以释放为主,中部和南部以滞留为主;在较长时间尺度内,外海北部和中部沉积物磷以释放为主,南部的以滞留为主.控制滇池沉积物磷释放需要考虑不同磷形态特征及有机质和粒径的影响,采取相应措施以主要控制滇池北部沉积物磷的释放.
