| 摘 要： | 通过2002年和2003年对东北地区松花湖水体富营养化状况进行调查和采样分析，对大量数据的多元相关分析和多元逐步回归分析、AGP试验和利用综合营养状态指数法进行评价。结果表明：松花湖处在中营养和轻度富营养状态；总磷是限制水体富营养化的主要因子之一。水体中变温层的形成，限制了上、下层湖水的混合，对下层水体中的溶解氧、无机氮和可溶性磷酸盐产生影响，随着变温层的消失，下层内的营养物质转移到湖上层，为藻类的繁殖提供条件。 |

| Abstract: | The eutrophication level in the Song hua lake, Northeast China was investigated in 2002-2003. Investigation and experimental data were processed and analyzed by the multiple correlation and multiple stepwise regression methods. And the eutrophication level in the Song hua lake was assessed by AGP test and the complex index of nutrients state. The results indicated that the Songhua lake was in the mesotrophication level, where total phosphorus content in the lake was one of the effective factors of the eutrophication level in the Song hua lake. The results from the water temperature monitoring showed that metalimnion has been formed in the Song hua lake, the metalimnion location was deepened from the summer to the autumn, and then which was gradually disappeared from the autumn to the winter. Mixing of upper and down lake water was limited because of the metalimnion exist. It made dissolve oxygen content decease in down water of the Song hua lake, but there inorganic nitrogen and PO 3- 4-P content were higher than that of upper lake water. With the metalimnion disappeared upper and down lake water were mixed. The nutrient matter in the down lake water would be moved to upper lake water. It would provide sufficiently nutrient matter for the algal growing in next year. |
