衣藻增殖、悬浮与沉降过程对水-泥界面磷素动态的影响
DOI: 10.3969/j.issn.1000-2006.2014.06.012, PP. 60-64
Keywords: 莱茵衣藻,磷素,碱性磷酸酶,水华
Abstract:
为阐明水华过程藻群动态对水-泥界面磷素变化的影响,采集太湖梅梁湾水样和泥样,以莱茵衣藻(chlamydomonasreinhardtii)为对象,通过室内模拟实验(76d),研究藻体增殖、悬浮与沉降过程水-泥界面不同形态磷素含量及碱性磷酸酶活性(apa)的变化。结果表明:衣藻快速增殖与悬浮导致水体ph与do含量明显升高,总磷和无机磷浓度迅速降低,但底泥有机磷含量平均高出无藻处理1.5倍。此外,衣藻沉降期底泥水溶性磷含量明显降低,这是由于部分沉降在底泥表面的藻体继续存活并吸收利用了水溶性磷。上覆水apa在藻体大量沉降后平均高于增殖和悬浮期1～3倍。相比较而言,底泥apa在藻体快速增殖与悬浮期达到最高,此后,apa降低,但仍高于无藻处理2倍以上。因此,衣藻水华过程加速了水-泥界面磷素的释放,部分沉降至底泥表面的存活藻体吸收利用磷素进而增殖和再悬浮,这可能是富营养化水体水华反复和多次暴发的重要原因之一。
