| 摘 要： | 广东省肇庆七星岩是我国著名的风景游览胜地 ,里湖是其中的重要组成部分。面积约 2 .6× 1 0 5 ｍ2 ,近年来 ,里湖水质有劣化趋势 ,表观上出现不同颜色 ,有藻类突发现象。对景区产生不良影响。既往研究表明 ,影响里湖水质的关键组分除浮游藻类叶绿素ａ与氮、磷含量之外 ,水中的ＤＯ和ＣＯＤ、ＢＯＤ也是极其重要的指标。研究它们的相互关系 ,旨在探讨其内在联系及变化规律 ,对于湖泊生态环境的保护和水污染的治理具有重要意义。1 研究材料与方法1 .1 主要仪器日立Ｆ -30 0 0型荧光分光光度计 (日本) ;ＷＺ -80 0Ｄ2 型紫外分光光度计(北京…

| Abstract: | Four seasonal field investigations have been conducted in the Seven Stars Lake in Zhaoqing between Apr.1996 and Jan.1997. The water of the lake was sampled once for each season. Three major eutrophication elements, phytoplankton,nitrate and phosphate were analyzed quantitatively. According to the monitoring data,the concectration levels of the elements and their distributions,relationships among the elements were analyzed. The results are important for predicting eutrophication of the water and studying the mechanisms of the eutrophication in the Seven Sear Lake. |
