摘要: |
测定了1998-2000年冬、春季太湖梅梁湾口雨水、地表径流水的pH值和N、P等营养元素化合物离子浓度.因降雨带进太湖的TIN、PO43-和COD分别占同期入湖TN、TP和COD总量的9.8%-15.5%、1.9%-2.2%和3.5%-6.0%;依据1999年冬、春季太湖梅梁湾口湖水总硬度和总碱度测定值,结合历史资料分析,指出湖水总硬度对总碱度比值的升高是太湖水体生态系统受持续性酸性降水长期影响的一种反馈形式 |

Abstract: |
It has been measured that the pH value and concentrations of nutrients such as N and P etc. in the rain and runoff at the mouth of Meiliang Bay, Lake Taihu from January 1998 to June 2000. Due to the affection of rainfall, the TIN, PO43- and CODMn are amounts to 10-15%, 2.0% and 4-6% of the total pollutes loads that was enter to the lake in the same period respectively. It was measured also that the total hard ions and alkalinity concentrations at the mouth of Meiliang Bay, Lake Taihu, in the March-June of 1999. According to the analysis with historic dada it has been found that the ratio of total hard ions over to the alkalinity in water of lake was raised with time. This phenomenon could reflect the response of aquatic ecosystem, Lake Taihu, to the deposition of acid rainfall in long term. |
