滇池北部示范区沉积物磷的分布特征研究

Distribution of Phosphorus in the Sediments of the Pilot Zone in the North Bay of Dianchi Lake

在滇池北部示范区内、外布点5个,采集原状低扰动柱状沉积物样品,分析样品中总磷(TP)、无机磷(IP)和有机磷(Org-P)的含量,研究了磷的垂向分布特征和形成原因。得出示范工程对沉积物中磷具有显著削减作用的结论。

Five sediment samples inside and outside of the pilot zone in the North bay of Dianchi lake were collected to test the distribution of phosphorus. The vertical distribution of phosphorus as well as itsformation was identified and compared to each other according tothe results of total phosphorus（ TP）,inorganic phosphorus（ IP） and organic- Phosphate（ Org- P）. The results showed that thepilot project worked well to reduce the content of phosphorus significantly in sediments inside of the pilot zone.
