英文摘要	Floodplain hydro-geomorphology is the major factor for vegetation growth and biomass. Characterizing interaction between the vegetation and hydro-geomorphology is essential to better understanding river ecosystems in arid regions. In this study, considering the various hydro-geomorphological dynamics of floodplains, the study area was divided into four functional zones and spatialized lateral variations of the floodplain fluvial disturbance intensity, sediment erosion and deposition process, moisture dynamics and vegetation growth condition through Landsat and daily Moderate Resolution Imaging Spectroradiometer (MODIS) time series between 2010-2015. And analyzed the various interactions between floodplain vegetation and hydro-geomorphology in different floodplain lateral zones. Results shows that the highest vegetation NDVI values (>0.4) are distributed in the regularly static floodplain area where characterized regular flood inundation and has moderate moisture ability. Vegetation NDVI values in the frequency inundation, wet and highly dynamic floodplain area are mainly less than 0.2. Results indicate that different hydro-geomorphological processes dominated in floodplains, therefore plants and hydro-geomorphology interact each other in different ways from river to floodplain margins. Using remote sensing time series can be better characterizing the different interactions between floodplain vegetation and hydro-geomorphology. This study can help to better management of river ecosystems in the arid region floodplains.
