摘要: 为了测评东钱湖的水质营养化状态,从2014年4月到9月监测湖水温度、透明度（SD）、水质总氮（TN）含量、总磷（TP）含量、叶绿素（Chla）含量以及沉水植物生物量的变化情况。结果显示,湖水水温缓慢增加到8月中旬,而TP含量、TN含量、Chla含量以及沉水植物生物量的动态变化特征具有明显的统一性,即东钱湖的水质在沉水植物和浮游植物的生长前期较为劣质。相关性分析表明,沉水植物生物量与TP和TN为高度负相关,而与水温为正相关。综合分析后认为,沉水植物生物量的增加是导致后期东钱湖水质转换的关键因素,说明沉水植物对东钱湖水生环境稳态转换具有重要作用。

Abstract: From April to September 2014, variation of water temperature, transparency, contents of total nitrogen (TN), total phosphorus (TP) and chlorophyll (Chla) of Dongqian Lake and the biomass of submerged plants in the Lake were monitored for determination of the eutrophic status of the Lake. The results showed that when the water temperature increased gradually till the middle of August, dynamic changes of the contents of TP, TN and Chla as well as the biomass of the submerged plants appeared obvious uniformity. That was, water quality of the Lakes was inferior at the early growth period of the submerged plants and phytoplankton. Correlation analysis showed that the biomass of submerged plant was highly negatively correlated with the contents of TP and TN but positively correlated with the water temperature. After comprehensive analysis, it was considered that the increased biomass of the submerged plants was the determinant for water quality shift of the Lake in the later phase, indicating that submerged plants played an important role in the steady-state shift of the aquatic environment of Dongqian Lake.
