Natural education is an important starting point for the construction of ecological civilization,and the professional skills of natural education tutors are key elements that drive the high-quality development of the natural education industry and affect the effectiveness of experience. A questionnaire survey was conducted and analyped,with SPSS 24.0 software.The exploratory factor analysis was used extract,the core dimensions of natural education tutors' skills. Then,multiple linear regression analysis and difference tests were applied to evaluate the relationship between each core dimension and emperience effectiveness,analyze the differences in tutors' skill evaluations among experiencers with different demographic characteristics,and explores the key factors influencing the effectiveness of natural education activities. The results show that:1) The core dimensions of natural education tutors' skills include ecological literacy and basic skills,curriculum design and interactive perception skills,as well as guiding exploration and interpretation skills.2) The tutors' ecological literacy and basic skills,as well as their skills in guiding exploration,thinking and explanation,can exert a significant positive impact on the experience effectiveness. By contrast,there is no statistically significant correlation between the tutors' curriculum design and interactive perception skills and the experience effectiveness.3)There are significant differences in experiencers' evaluations of tutors' curriculum design and interactive perception skills based on their educational levels;4) Overall,participants gave high ratings to all three dimensions of the tutors' skills,indicating that the groups participating in natural education activities expressed a high level of satisfaction with the tutors' professional competencies. Nevertheless,there is still room for further improvement. Enhancing tutors' ecological literacy and basic skills,as well as their skills in guiding exploration,thinking guidance and explanation,and providing differentiated natural education experiences,is conducive to optimizing the design of natural education courses,improving the teaching quality of tutors,and holds great significance for promoting the professional development of natural education.
