In the Southern Dynasties, Liang Jiangyan wrote "Ode to the Moss": "If you are in the water, the mirror will bring lakes and rivers, and the forest will be flowered." Sha Ting's He Long: "The lakes and mountains in those areas have become the graves of enemy mechanized troops!" Ai Qing's poem "Dongshan Huihai": "No matter the waterfall in the forest, no matter the reflection in the lake, the moonlit night in early spring and the morning light in Shan Ye, it is saturated with the painter's love."
Basic Introduction Chinese Name: Lake and Marsh mbth: Lake and Marsh Athena Chu: hüzh?o Interpretation: The water surface on land is big or small, deep or shallow. Related Poems: The theme of "Tai Fu" is limnology, paleolimnology, limnology, limnology, limnology, limnology, limnology community, China Marine Limnology Society, construction purpose, business scope, academic activities, limnology in a broad sense, and it is a study of land and water. Modern limnology mostly refers to limnology in a narrow sense, that is, limnology with inland static water as the research object, excluding flowing water as the research object. In other words, limnology is a science about limnology. Oceanography is the study of the ocean, so the study of physical, chemical and biological phenomena in inland waters, such as lakes, rivers and groundwater, is called limnology. P.S.Welch( 1952) regards this subject as a branch of ecology, which is limited to the study of biological production on land and in water and its influencing factors. Paleolimnology Paleolimnology is a branch of hydrogeology, which studies inland water bodies from the perspectives of chemistry, physics, hydrology and geology, including natural and man-made lakes, swamps, ponds, streams, rivers, wetlands and groundwater. Through the detailed analysis and study of many well-preserved paleolimnological evidences around the world, we can get a lot of information about the evolution history of the lake. The dynamic change of lake surface is controlled by climatic factors, so it has become a main branch of lake environment research. This paper briefly describes the evidence of paleolimnology from five aspects: geomorphology, facies association and sedimentology, geochemistry, paleoecology and archaeology, in order to restore the past lake evolution history more accurately and provide strong evidence for the study of regional and global environmental evolution. Plankton in lakes and swamps English name: limnoplankton Definition: Plankton that can only live in fresh water and still water. Applied disciplines: ecology (first-class discipline), water ecology (two disciplines), lake fish; ; lacustrine fish
Definition: Fish that inhabit lakes and swamps. Applied disciplines: aquatic science (first-class discipline), basic aquatic science (two disciplines) Lake-student wetland English name: Definition: wetland formed by the swamping process of coastal or shallow lakes in still waters such as lakes. Including shallow lakes, reservoirs and large ponds. The Ramsar Convention on Wetlands included the lake itself in the scope of wetlands. Applied disciplines: ecology (first-class discipline), water ecology (two disciplines) Lake and swamp communities are mainly composed of lake and swamp zoobenthos. It consists of green plants as producers, animals and fungi as consumers and bacteria as decomposers. These biological communities and the still water environment (lens environment) constitute a relatively closed lake ecosystem. The light transmission intensity is above the assimilation and respiration compensation point, which is the shallow surface layer or nutrient production layer of the lake where green plants can grow; The part below this layer is the deep water layer or the nutrient decomposition layer. There is a variable water layer between the two water layers. The bottom of the nutrient production layer is called the coastal zone. The bottom of the nutrient decomposition layer is called the deep bottom layer. The uppermost part of the deep seabed zone with large dip angle is called the sub-coastal zone. There are emergent plants, floating plants and submerged plants living in coastal areas. Plankton lives on the surface of shallow lakes far from the shore. Biological debris deposited in the nutrient decomposition layer and the bottom of the water is decomposed by bacteria, releasing nutrients such as N, P and K.. China Ocean and Lake Society (hereinafter referred to as Society) is referred to as China Ocean and Lake Society (hereinafter referred to as CSOL). China Ocean and Lake Society is a non-profit academic organization with legal person voluntarily composed of ocean and lake workers. It is an important social force for the development of ocean and lake undertakings in China and a part of China Association for Science and Technology. There are nearly 8,000 members, including professional committees 18, 9 local branches and 4 working committees. Construction purpose: conscientiously implement the party's basic line, abide by the Constitution, laws, regulations and national policies, and abide by social ethics. Carry out the spirit of democratic organization, unite and mobilize scientific and technological workers in marine lakes and marshes to focus on economic construction, adhere to the idea that science and technology are the primary productive forces, implement the strategy of rejuvenating the country through science and education and sustainable development: the policy of "letting a hundred flowers blossom and a hundred schools of thought contend", fully carry forward democracy and conduct free academic discussions. Advocate dialectical materialism, adhere to the scientific attitude of seeking truth from facts and excellent style of study, and carry forward the fashion of "respecting knowledge and talents". Advocate the spirit of dedication, innovation, truth-seeking and cooperation, unite the vast number of marine and freshwater workers, promote the prosperity and development of marine and freshwater technologies, promote the popularization and promotion of marine and freshwater technologies, promote the growth and improvement of marine and freshwater talents, promote the combination of marine and freshwater technologies and economy, serve the construction of socialist material civilization and spiritual civilization, hold high the banner of patriotism, safeguard national unity, promote the reunification of the motherland, and serve China's socialist modernization.
