| 摘 要： | 通过分析三峡库区新生典型消落区上覆水及沉积物中磷的赋存形态，揭示消落区沉积物中磷的分布特征和释放规律. 结果表明，不同类型的新生消落区沉积物磷的分布特征与消落区类型、原有使用背景、临时性使用情况等因素有关. 消落区类型对消落区上覆水ρ(总磷)的影响较弱. 消落区沉积物w(活性磷)与淹没状态相关，由露出到淹没状态活性磷逐渐减少，沉积物中w(钙磷)和w(闭蓄态磷)相对较恒定. 受水陆交替非稳态环境因素的影响，水陆交替沉积物w(总磷)相对较低. 消落区沉积物与上覆水中磷的迁移、转化主要以活性磷的释放和沉积为主.

| Abstract: | The distribution characteristics and release regulation of phosphorus dispersed in the sediments were revealed by the analysis of phosphate in the overlying water and sediments in the newly emerged typical fluctuation zones in Three Gorges Reservoir Area(TGRA).The results show that the phosphorus distribution characteristics in sediments of different types of newly emerged fluctuation zones are relevant to the varying categories of fluctuation zones,the original zone conditions in use,and the temporary zone... |
