Abstract:
Nature reserves, as important platforms for ecological civilization education, can give play to the value of ecosystem products and highlight ecological and social benefits. The rich bamboo forest resources endow the Sichuan Changning Bamboo Sea National Nature Reserve with highly representative and unique ecological education functions in terms of ecological value, cultural connotations, and aesthetic forms. In order to explore the development space of the specific value of bamboo ecological culture in nature reserves and promote the formation of the social-ecological civilization concept, the present study conducts an evaluation and study on the ecological education value of bamboo resources in the Changning Bamboo Sea National Nature Reserve in Sichuan. Methods: Over a period of more than two years, a comprehensive analysis was carried out by conducting field surveys in nature reserves, thus revising previous data. This study considered the climatic characteristics of the nature reserves, the geographical distribution of bamboo resources, and their development potential. It also referred to the practical application of eco-education and market demand, incorporating expert advice and relevant literature. The Analytic Hierarchy Process (AHP) was employed to develop a multi-lyered comprehensive evaluation model that includes target layer
A, criterion layer
C, index layer
P, and bottom layer
D. By calculating the weight of each factor based on pairwise comparisons within the model, an overall assessment of the bamboo species was achieved to evaluate and analyze the bamboo resources in the nature reserves. Results: (1) Based on the purpose of ecological education as well as the humanistic connotation and landscape form of bamboo plants, 12 three-level indicators were determined from three aspects: ornamental value, cultural popularization value, and application value according to expert evaluation. Besides, the evaluation system of ecological education value of bamboo resources in nature reserves was constructed. (2) The weights of the evaluation constraints were ornamental value (
C1) 0.4183, cultural popular science value (
C2) 0.3692, and application value (
C3) 0.2125, respectively. (3) AHP was used to screen and evaluate 56 species of bamboo plants. In addition, the development and utilization levels were classified into 4 levels. To be specific, there were 11 species of bamboo in Grade Ⅰ, with high utilization value. There were 17 species of bamboo in Grade Ⅱ, with relatively high utilization value. There were 13 species of bamboo in Grade Ⅲ, with low utilization value. There were 15 species of bamboo in Grade Ⅳ, with low development and utilization value. Conclusion: Based on the system′s scoring results, Grade Ⅰ and Grade Ⅱ bamboo species were selected for application discussions from three dimensions: space construction, cultural popularization, and industrial development. A population model
Indocalamus longiauritus-
Bambusa multiplex-
Phyllostachys edulis f.
bicolor was proposed. This study explored bamboo eco-education projects in an interdisciplinary context, and provided a sustainable industry upgrading approach centered on new high-quality productivity for bamboo resource conservation in the Southwest region, which holds significant value for broader promotion.
