| 摘 要： | 研究了典型城市浅水湖泊莫愁湖沉积物中磷形态及间隙水中TDP、PO43--P含量的垂向分布情况,沉积物中IP是TP的主要组成部分,与湖泊富营养化密切相关的Fe-P占IP的30%左右,Or-P占TP的30%左右。柱状沉积物中磷形态的垂向分布规律比较复杂,但基本上随深度先增后减的趋势。沉积物中TPI、P、Or-P、Ca-P、Fe-P、DP之间都具有极显著的正相关关系,但与Al-P、Oc-P的相关关系不明显,间隙水中TDP、PO43-P浓度与沉积物中Or-P含量具有显著的正相关关系,但相关程度并不高,与其他形态则没有明显的相关关系。

| Abstract: | Phosphorus forms in sediments and vertical distribution of phosphorus forms in interstitial water of typical urban shallow lake Mochou were investigated.IP(inorganic phosphorus) was the major part of TP,Fe-P(Ferrum phosphorus) was closely related to eutrophication,which accounted for about 30% of IP,Or-P(organic phosphorus) accounted for about 30% of TP.Vertical distributions of phosphorus forms in core sediments were complicated,basically exhibited a trend of firstly increased and then decreased with depth... |
