中文摘要:
      在2003年10月27、28日和2004年8月19日的太湖水质试验数据基础上,研究与探讨了氮浓度、磷浓度与叶绿素a浓度、悬浮物浓度和CDOM(Colored Dissolved Organic Matter)浓度之间的定量关系。研究结果表明:①在2003年10月份和2004年8月份,太湖梅梁湾地区水体的氮、磷浓度介于1~4mg/L和0.1~0.3mg/L,该浓度恰好处于易发生水华的营养物质浓度供应区间;②与2004年8月19日相比,2003年10月27、28日的太湖藻类处于低增长、高消亡状态;③在太湖梅梁湾地区,氮、磷浓度与CDOM浓度、叶绿素a浓度和悬浮物浓度之间存在较强的线性相关性,其相关系数大于0.557;④在太湖水体中,磷浓度、CDOM浓度、叶绿素a浓度和悬浮物浓度的四因子关系模型比氮浓度、CDOM浓度、叶绿素a浓度和悬浮物浓度的四因子关系模型的相关系数高。
英文摘要:
      Basing on the in sute measurements collected at 27, 28 October, 2003 and 14 August, 2004, the quantitative relationship between nitrogen concentration, phosphorus concentration and chlorophyll-a concentration, CDOM (Colored Dissolved Organic Matter) concentration, and suspended sediment concentration was discussed by this paper. According to the analysis results of this paper, it was found that: ① On October, 2003 and August, 2004, the nitrogen concentration and phosphorus concentration were ranging from 1 mg/L to 4mg/L and from 0.1mg/L to 0.3mg/L, respectively. The concentration at that range was greatly suitable for the algae broom. ②By comparison with the algae growth status at 14 August, 2004, the algae is at low increasing rate and at high decay rate at 27, 28 October, 2003.③In the Meiliang bay of Taihu lake, the nitrogen concentration, phosphorus concentration were perfectly linear dependent on the chlorophyll-a concentration, CDOM concentration, and suspended sediment concentration, and the corresponding correlative coefficient was more than 0.557.④In the water bodies of Taihu Lake, China, of the correlative coefficient of four factors model of phosphorus concentration, chlorophyll-a concentration, CDOM concentration, and suspended sediment concentration was higher than the four factors model of nitrogen concentration, chlorophyll-a concentration, CDOM concentration, and suspended sediment concentration.
