Abstract

Macrophyte is an ecologically-diverse taxon that consists of a type of different groups of plants that adapt to the aquatic environment over a long period of time, such as aquatic vascular plants and higher algae (Chara, etc.). Macrophytes can be classified into four different types based on growth form: Emergent macrophytes, floating macrophytes, floating-leaved macrophytes and submergent macrophytes. Aquatic macrophytes exist between water-sediment, water-air and water-land interface. They are important components of the lake ecosystem and are important regulators of lake evolution and lake ecological balance. Besides, they improve water quality and increase the stability of water environment by inhibiting the growth of phytoplankton and thus reduce the stock of algae. So they are often used as indicators of changes in the lake environment and as a basis for establishing good lake ecology.
