摘要
徐州市云龙湖是典型的浅水性城市湖泊,由于城市人口增加,城市湖泊负荷过重,可能导致湖泊水体富营养化。对云龙湖分布于东、西两湖的4个采样点进行采样,利用综合营养状态指数法对叶绿素a、总氮、总磷等相关指标进行分析,得到近7年来两大不同功能区水体的营养化特征及变化规律。最后评价结果显示,云龙湖水体多年稳定地处于中、贫营养化状态。西湖富营养化程度比东湖高,夏季富营养程度高于冬季,说明不同的湖区功能和温度都会影响富营养化程度。笔者通过开展此项研究分析,掌握了云龙湖水体污染特征和变化规律,可为有关部门采取云龙湖治理措施提供依据。
Yunlong Lake in Xuzhou City is a typical shallow water city lake. Due to the increase of urban population, overload of urban lakes may result in eutrophication of lake water bodies. Four sampling sites of Yunlong Lake located in the east and west lakes were sampled, and the related indicators such as chlorophyll a, total nitrogen, and total phosphorus were analyzed using the comprehensive nutrition state index method. Four sampling sites in Yunlong Lake located in the East Lake and West Lake were sampled. Comprehensive indicators of nutritional status were used to analyze chlorophyll a, total nitrogen, and total phosphorus. The trophic characteristics and changing rules of water bodies in two different functional areas in the past seven years were obtained.The final evaluation results show that the water of Yunlong Lake has been steadily in the middle and poor trophic state for many years. The degree of eutrophication of West Lake is higher than that of East Lake. The degree of eutrophication in summer is higher than that in winter, indicating that different lake functions and temperatures will affect the degree of eutrophication. By carrying out this research and analysis, the author grasped the characteristics of pollution and the law of change in the water bodies of Yunlong Lake, which provided the basis for the relevant departments to take measures to control Yunlong Lake.
