英文摘要	As a transitional zone between terrestrial and aquatic ecosystems, riparian ecosystems are critical in maintaining the health of river-ways and watersheds, and particularly sensitive to changes in hydrological regimes. Effects of dams on riparian zone are widely addressed, but less attention focus on riparian plant community of bar habitats. The Jingjiang reach downstream of the Three Gorges Dam has undergone significant changes of water and sediment condition and local base-level due to the Three Gorges Dam. To address responses of riparian plant communities to dams, the riparian plant communities of the mid-channel bars and the point bars in the Jingjiang reach were examined with a trait-based analysis. The results showed a lower species richness and a higher risk of invading by invasive species for mid-channel bars comparing with point bars. Moreover, the species richness of both the mid-channel bars and the point bars were observed increasing with the distance increasing from the dam, but the increasing rate of mid-channel bars was much smaller than that of point bar. Furthermore, functional redundancy of the mid-channel bar represented by the difference between functional diversity and species richness was marked lower than that of the point bars. Thus, we conclude that affected by the regulation of the dam, the mid-channel bars seem to be more hydrologically susceptible and harsher habitats for the assembly of plant community comparing with point bars. Therefore, more research of mid-channel bar downstream the dam were suggest and different emphasis of research and protecting management are needed for different bar types.
