Table 5: Average scores of demographic characteristics on influencing dimensions. activities. Educational background is a comprehensive influencing factor, but the higher the level of education, the stronger the ability to capture information and the higher the environmental cognitive potential. In addition, gender and age have certain effect, but their difference is not significant. The above results indicate that there are significant generalizability and representativeness. Both guided and self-help education modes have significant positive influence on the perception and effectiveness of environmental education, which is consistent with other similar studies. It is indicated that different education models have universal applicability in improving the effectiveness of environmental education [34]; moreover, open space and interactive facilities can significantly improve tourists' perception and effectiveness of environmental education. Similar studies have reached similar conclusions in other national parks and nature reserves, that is, spatial design plays important role in environmental education [27]. At the same time, stratified random sampling method was used to ensure the gender representiveness of samples. The male to female ratio in the study is determined to be 55:45, which is consistent with the actual sex ratio of tourists in Wuyi Mountain National Park, thus improving the external validity of the results in previous studies. Based on the above discussion, the following suggestions were proposed to improve the effectiveness of nature education. 1. Improvement of resource element interpretation system. The perception and effectiveness of environmental education are affected by the interpretation of resource element. Therefore, it is necessary to improve the connotation of resource element interpretation system in national parks. First of all, we need to sort out knowledge resources of environmental education in Wuyi Mountain National Park, focus on local knowledge, and systematically plan the environmental education knowledge system in Wuyi Mountain National Park. Secondly, we should improve the usability and convenience of resource element interpretation media to increase the depth of perception and effectiveness of environmental education. 2. Design of environmental education space combined with tourists' preference. The planning and design of environmental education space should integrate the characteristics of national parks and tourists' personality perception. As a key element to enhance perception and effectiveness, open space should be considered as the focus of environmental education space design.
