浅水湖泊草-藻型稳态转换理论研究进展

Study progress of steady-state transformation theory of phytoplankton and macrophyte in shallow lakes

浅水湖泊是地球表层水体的重要构成之一,其在生物多样性保护及区域社会经济发展等方面发挥着重要的作用。气候变化和高强度的水资源开发利用导致湖泊物理、化学特性在时空格局上发生了显著变化,同时也引起一系列的社会、环境、气候等负面响应。以长江流域浅水湖泊稳态转换理论研究为例,介绍了太湖、洞庭湖及滇池等典型浅水湖泊稳态转换理论研究过程中解决众多的理论和实际问题,为区域发展提供了强大支撑;同时对浅水湖泊水生植物适宜生物量评估方法进行总结归纳,展望了浅水湖泊稳态转换理论研究存在的问题及未来需要突破的研究难点。

Shallow lakes are important components of the Earth s surface water bodies.They serve as irreplaceable functions in regional socio-economic development and conservation of biological diversities.Climate variations and intensive water consumption result in significant deviations in temporal change and spatial pattern in terms of physical and chemical processes.Taking the steady-state conversion theory research of the shallow lakes in the Yangtze River Basin as an example,this paper introduces multiple theoretical and practical problems solved in the study of steady-state conversion theory of typical shallow lakes such as Taihu Lake,Dongting Lake and Dianchi Lake.Meanwhile,the methods for setting suitable biomass of aquatic plants in shallow lakes were summarized.Finally,the remaining problems and difficulties in the study of steady-state transformation research of shallow lakes are discussed.
