Human activities, whose main carrier is large-scale engineering, make comprehensive impacts on ecosystem servies by altering habitat, ecosystem structionand biogeochemical cycles. Large-scale basin engineering influences directly material fluxes and their compositions from river discharge into the sea by changing esturine habitat and biogeochemical cycle. However, large-scale estuarine engineering affects directly estuarine ecosystem mainly by altering local estuarine habitat.
