The dynamic density functional theory（DDFT）was used to study the autocongregation effects of diblock copolymer and triblock copolymer surfactant on the mesoscopic structure with the objects PEB［（PEO）11-（PBO）11］and PL64［（PEO）13-（PPO）30-（PEO）13］.Under the autocongregation effect，the multilamellar vesicles of PEB were observed.A much greater lamellar number would be observed if the initial PEB congregation had better autocongregation，and on the contrary，much more water would be contained in the multilamellar vesicle if the initial PEB congregation had worse autocongregation.Under the autocongregation effect，the spheric mesoporous structure and congregation structure of spheres and coshes of PL64 were also observed.Furthermore，through depicting the evolution of order parameter and morphology，the formation mechanisms of the multilamellar vesicle of PEB，the spheric mesoporous structure and congregation structure of spheres and coshes of PL64 were presented.
