In this paper, the research progress and the character of ecological factors in agroforestry was briefly described. The light, temperature, humidity, soil water content, wind speed, soil nutrition, economic and ecological benefits in agroforestry systems etc. were summarized. We indicated the advantages and disadvantages in agroforestries related to high yield and resource use. It is suggested that the agroforestry systems could improve productivity with optimizing nature resources.
