Advances and prospects in lake environment science and engineering: A review

Abstract

Lake environment and engineering is an interdisciplinary basic research and applied research discipline, which is developed in recent 10-20 years, and studies the evolution law, interactive mechanism, protection and governance and harmonious development of lake water environment quality under changing environmental conditions. With the increasing intensity of human activities, lakes in China are faced with severe environmental problems such as eutrophication, cyanobacteria blooms and secondary disasters, and persistent and emerging pollution. It is urgent to develop regional integrated pollution prevention and control technology system for lake environment protection, to serve the national ecological civilization construction. This paper at first briefly introduces the concept and connotation of Lake Environment and Engineering; systematically describes the research on environmental behavior and reduction of major pollutants in lakes in recent 10 years around the world; analyzes the causes and control strategies of secondary disaster "black water" mainly caused by cyanobacteria bloom, and then shows the lake monitoring methods mainly based on lake sediment; summarizes the technical research development about lake pollution prevention and control. Finally, the paper looks forward to the extension of the research scale of lake environment and engineering to macro and micro dimensions, and the integration of ecological / hydraulic engineering and smart perception / big data technology.
