摘要
巢湖水体的氮、磷和叶绿素a的研究已取得较多进展,但关于其四季时空赋存特征及其与环境因子相关性的研究仍匮乏.本研究于2021年1月、4月、7月和10月对巢湖湖区开展了氮、磷和叶绿素a及环境因子的全面研究.结果表明,巢湖的主要污染物是总氮和总磷,西半湖污染高于东半湖;氨氮、总氮比总磷和叶绿素a对夏季巢湖水体富营养化的贡献更大,温度和溶解氧对夏季水华的发生产生促进作用;氮、磷和叶绿素a动态变化的影响因素具有季节特异性.
Abstract
More progress has been made in the study of nitrogen,phosphorus and chlorophyll a in the waters of Chaohu Lake,but there is still a lack of studies on their spatial and temporal fugacity characteristics in all seasons and their correlation with environmental factors.In this study,a comprehensive study of nitrogen,phosphorus and chlorophyll a and environmental factors in Chaohu Lake was conducted in January,April,July and October 2021.The results showed that the main pollutants in Chaohu Lake were total nitrogen and total phosphorus,with higher pollution in the western half of the lake than in the eastern half;ammonia nitrogen and total nitrogen contributed more to the eutrophication of Chaohu Lake waters in summer than total phosphorus and chlorophyll a.Temperature and dissolved oxygen contributed to the occurrence of water blooms in summer;and the factors influencing the dynamics of nitrogen,phosphorus and chlorophyll a were seasonally specific.
