摘要
对广东省惠州西湖富营养化现状进行了调查,结果表明,惠州西湖生态系统退化严重、系统的自净能力低、几乎没有大型水生植被,加之湖水浅、沉积物颗粒细以及大量的鱼类活动,造成水体中营养盐和总悬浮物浓度高、透明度低。内外源污染共存是惠州西湖富营养化的主要原因。因此,惠州西湖要实现水环境的根本好转,不仅要削减外源污染,还需进行生态系统修复。
The investigation was carried out on Huizhou West Lake to understand the environment conditions.The results showed that ecological degradation was very seriously and itself depurative ability was very low. There was almost no aquatic macrophyte vegetation,but a great deal of fish living in it,on the other hand,the lake was shallow and the grain of the bottom mud was small. So,it was easy to make the nutrient salt and total suspended particle concentration in water high and the transparency low. Interior and exterior pollution sources coexisting was the main reason for eutrophication of the lake.So,in order to make the water quality good completely,it should not only cut off the exterior pollution sources,but also do the ecological restoration in the lake.
