Abstract: The research on hydrologic and thermal characteristics is important to the ecological benefits quantification, structure optimization, and management improvement of agro-forestry system (AFS). The Chinese and English literatures on radiation, evapotranspiration or transpiration, soil moisture, root system and water use efficiency characteristics of AFS from 1980 to present was retrieved and analyzed in this paper. The retrieved database included Science Direct, CNKI, Springlinker, CABI Abstracts, and the Chinese database of China Academy of Forestry Library. Moreover, the research advances of hydrologic and thermal characteristics of AFS in recent 35 years were summarized, and the prospects were proposed respectively. The objective of this study was to provide a reference for AFS research on structure and function. The results showed that: (1) the AFS could adjusted the solar radiation distribution and canopy heat balance. However, few studies have been performed to measure the light distribution in AFS quantitatively. (2) Because the systematic and integrated study on the mechanism of hydrological process was lacking, it was difficult to obtain a unified conclusion about the effects of AFS on water. (3) Even though the progress of water interaction under inter-species was obtained, the further study on water consumption sources, water transport, and water use efficiency of AFS was required. Moreover, the analysis of spatial and temporal variation of the interaction between inter-species was required in the future. (4) The most current existing data origin from the experimental measurements, and the representation was limited. Therefore, the further study on model simulation was required.
