By utilizing the coupled AVIM-RIEMS2.0, which was linked with the regional climate model RIEMS2.0 (Regional Integrated Environment Modeling System Version 2.0) by the land surface model AVIM (Atmosphere-Vegetation Interaction Model), and typical years were selected to perform integral experiments. The simulated results were compared with observations and reanalysis data to evaluate the performance of the coupled model over East Asia. The coupled model showed good performance in simulating the seasonal variation and spatial distribution of wind field at 850 hPa, geopotential height at 500 hPa, surface air temperature, precipitation, and surface heat fluxes. The capability of RIEMS2.0, which is a two-way model coupled with AVIM to include a dynamic vegetation process, showed improvement over the single RIEMS2.0. The wind at 850 hPa was obviously improved in northeastern and North China in winter and in eastern China in summer. Geopotential height at 500 hPa was captured in northern China but did not show obvious improvement in southern China in summer. The coupled model improved the surface air temperature, which was lower in winter and higher in summer than that simulated by RIEMS2.0. For the regional average, the coupled model reduced the overestimated precipitation simulated by RIEMS2.0 and more accurately simulated surface fluxes of latent and sensible heat in most areas of China. Overall, AVIM-RIEMS2.0 showed an obvious improvement in northern China, but not in southern China, and particularly in South China.
