The results show: (1)The relevant studies in the longitudinal time dimension have significant phase characteristics, and the literature originates from landscape planning and environmental resources journals. (2) High-frequency published author groups guide the main research directions in the field. Literature support institutions are mainly from many universities in Europe and America. (3) The main keywords are derived by co-occurrence, emergence, and timeline analysis in the horizontal keyword dimension-analysis of research frontiers in terms of practice design, child and adolescent developmental characteristics, and social attributes. (4) Based on research methods and perspectives to analyze the differential of related literature on important metrics and developmental levels. To address the shortcomings of existing studies and provide some reference for the future direction of green exposure research on child and adolescent health.
