description [Objective] The natural vegetation succession characteristics and influencing factors for a reclamation area in Tianjin City were studied in order to provide a scientific basis for ecological restoration and reconstruction of the reclamation area. [Methods] The plant community types, succession patterns and influencing factors in a reclamation area of Tianjin City were analyzed by field survey and sampling, laboratory measurements and TWINSPAN, detrended correspondence analysis and canonical correspondence analysis, etc. [Results] ① The natural vegetation succession sequence in the reclamation area of Tianjin City followed the order of: Ass. Suaeda salsa →Ass. Phragmites australis+Suaeda salsa →Ass. Aeluropus sinensis→Ass. Phragmites australis→Ass. Tamarix chinensis-Cynanchum chinense. Soil salinity gradually decreased and the number of the plant species gradually increased as succession proceeded. ② Total soil salinity, distance from urban secondary roads, and distance from the 15 m isobath were significantly different in different succession stages, and these were the main factors influencing the primary succession of vegetation in the reclamation area of Tianjin City. [Conclusion] Vegetation succession in the reclamation area of Tianjin City was affected by both natural and human factors. Scientific regulation of environmental factors (e.g. total soil salinity) could provide favorable environmental conditions for vegetation restoration in reclamation areas.
