, 2007 沉积物磷负荷在湖泊富营养化的发生与恢复过程中具有关键作用,其释放受物理、化学与生物机制调节,而碱性磷酸酶催化有机磷的矿化,故当为促进沉积物磷循环的重要因素。本文讨论了长江中下游部分湖泊沉积物碱性磷酸酶分布及其在磷释放过程中的作用。五里湖疏浚与未疏浚区以及太湖、巢湖、龙感湖、东湖、月湖、龙阳湖、莲花湖等不同湖泊的不同区域表层沉积物碱性磷酸酶活性(APA)明显不同,这种空间异质性与湖泊富营养化程度相联系。此外,APA随沉积物的深度递减,或在中间与较深层次出现峰值,且具明显的季节性 ...

, 1995 本文研究长江口和九龙江口悬浮物中磷的化学形态分布及不同环境条件下的转化与释放。结果表明，长江口和九龙江口悬浮物中易于溶解释放的非磷灰石无机磷分别占总磷含量之21.3%和48.1%。水体盐度增大、缺氧环境以及海洋浮游植物渗出物和海洋细菌的作用，均可不同程度地促进悬浮物中磷释放到水相，同时引起固相内部磷形态的转化。文中对悬浮物中磷的潜在生物可利用形态也作了初步探讨。The distribution and transFormation of diFFerent Forms of phosporus and ...
