摘要
惠州西湖属于城市浅水型湖泊,通过连续1个年度对惠州西湖5个子湖水环境、浮游植物、浮游动物和底栖动物及鱼类的调查分析,研究发现治理后的惠州西湖仍处于富营养化状态,水生生态系统结构简单,初级生产者只有藻类无水生植物,浮游动物、底栖动物种类少,鱼类单一,生态系统处于非健康状态。近年对西湖采取了开辟新水源、环湖生活污水截污、底泥疏浚等工程技术措施,治理措施的生态效果不明显,文章反思了治理措施的不足,认为应加强对城市浅水湖泊系统机理的研究,为湖泊的生态恢复提供理论和技术支持。
The Huizhou Westlake is a shallow lake in Huizhou city. Using present monitoring data,the ecosystem in the Westlake has been analyzed. The results show that the water body of the Westlake is euthrophicated, although at present the water quality is better than several years ago. Although some measures have been applied in recent years to control eutrophication （such as dredging sediment, introduction of reservoir fresh water into the Westlake, etc）, the deterioration tendency of the lake ecosystem has not been controlled efficiently. Aquatic ecosystem restoration should be adopted.
