目的 基于AHP-DEMATEL法对自然缺失症儿童玩具进行创新性研究，建立更加科学合理的设计体系，使设计方案更科学、全面。方法 通过文献整理、用户研究和专家评估，获取自然缺失症儿童玩具设计的各项指标要素，构建评价指标模型。运用AHP法和DEMATEL法分别对各项指标的初始权重和各指标之间影响权重进行评估。利用初始权重和影响权重求得综合权重，再以此为依据筛选关键指标因素，进行设计创新。结果 在自然缺失症儿童玩具设计当中，“自然体验”“人机尺寸”“教育性”等指标是关键评判标准，设计工作应重点围绕这些指标进行。结论 AHP-DEMATEL法的使用对设计流程的客观性显现具有显著意义，同时也能帮助研究者获取更客观合理的设计要素权重，在儿童玩具设计领域具备一定的参考价值。

The work aims to study the innovation of toys for children with nature deficit-disorder based on the AHP-DEMATEL method, and establish a more scientific and reasonable design system to make the design scheme more scientific and comprehensive. Through literature review, user research and expert evaluation, various indicator elements of toy design for children with natural deficit disorder were obtained, and an evaluation indicator model was constructed. AHP and DEMATEL methods were used to evaluate the initial weight of each indicator and the impact weight between each indicator. The initial weight and the influence weight were used to obtain the comprehensive weight, and then the key indicator factors were screened on this basis to carry out design innovation. The results showed that in the design of toys for children with natural deficit-disorder, "natural experience", "human-machine size", "educational nature" and other indicators were the key evaluation criteria, and the design work should focus on these indicators. The use of AHP-DEMATEL method has remarkable significance for the objectivity of the design process, and it can also help researchers obtain more objective and reasonable weight of design elements, which has certain reference value in the field of children's toy design.
