Abstract:

As one of the most typical wetlands,marsh plays an important role in hydrological and economic aspects,especially in keeping biological diversity.In this study,the definition and connotation of the ecological water storage of marsh is discussed for the first time,and its distinction and relationship with ecological water requirement are also analyzed.Furthermore,the gist and method of calculating ecological water storage and ecological water requirement have been provided,and Momoge wetland has been given as an example of calculation of the two variables.Ecological water use of marsh can be ascertained according to ecological water storage and ecological water requirement.For reasonably spatial and temporal variation of water storage and rational water resources planning,the suitable quantity of water supply to marsh can be calculated according to the hydrological conditions,ecological demand and actual water resources.

Key words: marsh, ecological water storage, ecological water requirement, Momoge wetland
