四川长宁竹海国家级自然保护区竹类资源生态教育价值评价

Evaluation on the ecological education value of bamboo resources in Sichuan Changning Bamboo Sea National Nature Reserve

  • 摘要: 自然保护区是开展生态文明教育, 发挥生态产品价值, 彰显生态社会效益的重要平台。为探索自然保护区竹生态文化特定价值的发展空间, 推动社会生态文明观的形成, 通过实地调查与层次分析法, 以四川长宁竹海国家级自然保护区为研究实验区, 对保护区竹类资源生态教育价值进行评价。研究表明:(1)基于生态教育目的与竹类植物人文内涵及景观形态, 按专家评定从观赏价值、文化科普价值和应用价值3个方面确定12个3级指标, 构建自然保护区竹类资源生态教育价值评价体系。(2)评价的约束层权重分别为观赏价值0.4183、文化科普价值0.3692、应用价值0.2125。(3)利用层次分析法筛选评价了56种竹类植物, 并将开发利用等级划分为4种级别, Ⅰ级有11种竹种, 利用价值高;Ⅱ级有17种竹种, 利用价值较高;Ⅲ级有13种竹种, 利用价值较低;Ⅳ级有15种竹种, 开发利用价值低。(4)据该体系下评分结果选择Ⅰ级、Ⅱ级竹种从“空间营造、文化普及、产业发展”三方面进行应用探讨, 提出可贯穿运用种群模式:“箬叶竹-孝顺竹-绿槽毛竹”, 并依此探索跨学科模式下的竹类生态教育方案, 以求向西南地区竹类自然保护地生态教育资源开发提供科学参考。

     

    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.
