The pro-environmental behavior of tourists (PEBT) can reduce the impact of tourism activities on the environment, which has attracted more and more attention from scholars. Based on the 159 articles of the PEBT from 2003 to the present in the “Web of Science” database, analyzing the overall characteristics, core knowledge, and knowledge evolution of this field with the help of CiteSpace and Vosviewer software, to systematically grasp the development panorama and find the future direction of the research on PEBT. The results show that economics, ecology, and psychology have a strong knowledge spillover effect for research on PEBT. Three regional research circles, eight-core scientific communities, and four core prior knowledge groups have formed for research on PEBT. The research content mainly focuses on exploring the measurement, forming mechanism, and influencing factors of PEBT. The effect of attitude or place attachment to PEBT has once been the research hotspot in this field. The research focus is to explore PEBT under multiple scenarios from the perspective of multi-disciplinary in recent years. Finally, a series of directions for future research on PEBT were put forward, aiming to bring some useful references to scholars.

旅游者亲环境行为（PEBT）可以减少旅游活动对环境的影响，越来越受到学者们的关注。基于“Web of Science”数据库中PEBT从2003年至今的159篇文章，借助CiteSpace和Vosviewer软件分析该领域的整体特征、核心知识和知识演化，系统把握发展全景并找到未来PEBT研究的方向。结果表明，经济学、生态学和心理学对PEBT研究具有很强的知识溢出效应。已经形成了三个区域研究圈、八个核心科学共同体和四个核心先验知识群，用于研究 PEBT。研究内容主要集中在探索测量、PEBT的形成机理及影响因素。态度或地点依恋对PEBT的影响曾经是该领域的研究热点。近年来的研究重点是从多学科的角度探索多场景下的PEBT。最后，提出了未来PEBT研究的一系列方向，旨在为学者们带来一些有益的参考。
