The process of hydrodynamic lake has directly and indirectly affected the material ,energy transmission and conversion,water-gas, water-soil interface to exchange ,which is the basis content of lake environment.Of the current shallow lakes hydrodynamic research fingdings indicate that the hydrodynamic effect is an important control factor of the shallow lakes evolution of the ecological environment,which has far-reaching implications in the waters of the lake ecosystem and the environment.For example,the nutrient-rich sediments in the bottom of lakes occurred suspension and removal in the waves and currents'force,which influence the release of the sediment nutrients,and lead to suspension in water quality conventration,and then colour and transparency. Meanwhile,with the development of economy,a large number of industrial waste water and domestic sewage drained into lakes.These pollutants occurred migration and proliferation in the power process,which created a series of environment impact to the lake.Thereforce,the dynamic process plays an important role in shallow lake ecosystems.Wave as an important motivating factor in the spread of material is different from other hydrodynamic factors.This paper first summarizes the research results of mechanism of pollutants under the hydrodynamic factors ,and a more comprehensive overview.According to content,the author designed research programs ,and conducted the experiments in the wave in different water depth and different elements of wave ,and summarized the law of dissolved pollutant transport and diffusion in form ,concentration and location in the instantaneous point source and continuous point source,and acquired some useful conlusions in the pollutants'transport and diffusion.
