摘要
从破坏植被加速湖泊淤积速度、围湖造田使湖泊日渐萎缩、江湖隔绝促进水生高等植物生长、垸湖沼同体而互相转化等方面论述了人类活动加速了江汉湖群湖泊沼泽化的进程,并提出缓解湖泊沼泽化的措施;人类活动既具有加速湖泊沼泽化进程的作用亦具有延缓甚至逆转沼泽化进程的双向作用。
The influence of human activities on the swamping of Jianghan lake groups is discussed as follows: The siltation of the lakes has been accelerated since plants in those lakes were destroyed as a result of human activities; Reclaimed land from lakes results in lake shrinking. The rivers and lakes in this area have segregated and led to an accelerating growth of the aquatic plants. Lake water pollution has already changed the relationship between aquatic plants and plankton. It is concluded that Jianghan lake groups may be withering into marshes and finally disappear if no measures are taken. Some suggestions to prevent them from being swamped are put forward.
