Abstract:

Azolla in regional water bodies plays an important role in maintaining the function of wetland ecosystem,material and energy cycles,and enhancing the self-purification capacity of water,but its excessive growth will reduce the wetland biodiversity,water quality and landscape benefits,threatening the function and structural stability of small wetland ecosystem. This paper reviews the comprehensive roles of Azolla in regional water bodies from the perspectives of resource utilization,environmental remediation,and ecosystem maintenance. In view of the overgrowth phenomenon of Azolla in small water bodies in southern China,the impacts of its massive proliferation and diffusion on regional water quality and landscape are summarized. Based on the growth,reproduction and distribution patterns of Azolla in regional water bodies and the influencing factors,this paper proposes ecosystem reconstruction and integrated regulation methods to prevent the excessive reproduction of Azolla,aiming to provide references for the comprehensive utilization and ecological control of Azolla.

Key words: Azolla, small wetland, resource utilization, differentiated strategies by time and zone, integrated control
