五大连池冬季水体中磷的分布特征

在冬季对东北地区五大连池各池采取表层水样,对水体中总磷、溶解性总磷和溶解性磷酸盐进行了分析。结果表明五大连池冬季水体中总磷浓度在0.035 mg/L～0.144 mg/L之间,其中四池含量最高,二池含量最低。溶解性总磷的含量在0.027 mg/L～0.049 mg/L之间,三池含量最高,一池含量最低。溶解性磷酸盐的浓度在0.020 mg/L～0.042 mg/L之间,三池含量最高,二池含量最低。水体中磷以溶解态的形式存在为主,而溶解态中又以溶解性磷酸盐为主,占溶解性总磷的平均百分比为80.92%。总的来说三池、四池和五池磷水平较高,人类污染影响严重。

Species Distribution of Phosphorus in Water of Wudalianchi in Winter

Geochemical forms of phosphorus in water samples from Wudalianchi in the northeast of China were investigated. The results indicate that：the TP content in surface water varied from 0. 035mg/L -0. 144mg/L, the content is the highest in the fourth pool, the content is the lowest in the second pool. The TDP content in surface water varied from 0. 027mg,/L - 0. 049rag/L, the content is the highest in the third pool, the content is the lowest in the first pool. The DRP content in surface water varied from 0. 020mg/L -0. 042mg/L, the content is the highest in the third pool ,the content is the lowest in the second pool. The TDP content was the main fraction of the TP. The DRP content was the main fraction of the TDP. The average values of DRP in TDP is up to 80. 92%. The content of phosphorus in the third pool, the fourth pool and the fifth pool is higher than the first pool and the second pool. The people play a significant role to the phosphorus.
