Abstract: With the advancement of the "14th Five-Year Plan" for the construction of child-friendly cities, it is necessary to take the initiative to explore strategies for improving the spatial environment according to satisfaction assessment of Learning Trail spaces in child-friendly neighborhoods. An essential component of urban commuting infrastructure, the Learning Trail spaces in old urban neighborhoods are both the physical spaces ensuring road safety, stability, and tranquility, and the emotional and socially inclusive spaces for vulnerable groups such as children. Studying old urban neighborhoods and building child-friendly Learning Trail spaces in neighborhoods can improve urban sustainability and inclusivity. It is also a key way to create a high-quality life and promote high-quality urban development. 
　　A case study based on the child-friendly Learning Trail spaces of the Zhaojue neighborhood in Chengdu was carried out. A standard evaluation system for the friendliness of Learning Trail spaces was built using data from semi-structured interviews, the photovoice method, and the Kano-AHP model. The system is composed of four criteria layers (safety of the "walking path", accessibility of the "arrival path", comfort of the "sensory path", and enjoyment of the "play path") and 28 indicator layers. Model data was also collected. The sensitivity coefficient of each indicator was calculated by using the Kano model. Later, fitting and optimization were conducted by combining the weights of evaluation indicators after satisfaction correction of users (children aged 3~12 and their guardians) in the AHP model and the comprehensive coefficient of expert evaluated weights of indicators. This study explored the demand types for Learning Trail spaces and the prior satisfied sequences of indicator factors. On this basis, some feasible strategies to improve child-friendly Learning Trail spaces were proposed.
　　Some major conclusions could be drawn: 1) road cleanness and educational intelligence significantly influence user satisfaction. Key attention is paid to ecological sustainability and thematic interest. 2) With respect to expert-evaluated weights of indicators, the safety of the "walking path" shows the highest weight, followed by the accessibility of the "arrival path". The comfort of the "sensory path" and the enjoyment of the "play path" show the lowest and equal weight. Users pay more attention to the enjoyment of the "play path". 3) The sequence for implementation is "constructing a safe and continuous path, configuring a comfortable and ecological sensory path, building an intellectually and enjoyable play path, and improving an accessible path to all age groups" .
　　Based on the current status and satisfaction evaluation of Learning Trail spaces, this study proposed the child-friendly principle, the systematic principle of multi-dimensional co-construction, and some optimization recommendations. 1) Constructing a safe and continuous "walking path" is the first step to enhancing the commuting environment and the basic physiological and safety needs of children. For instance, a 15-minute child-friendly travel network system should be developed to improve children's right-of-way. An early traffic system and late management mechanism should be established and perfected. 2) While meeting the basic needs of children, it should configure a comfortable ecological "sensory path" to transit toward the intermediate perceptual needs. For example, it can reshape the appearance of old urban areas and eliminate users' dissatisfaction by regular maintenance (e.g., pruning plants and clearing visual blind spots), and enhancing road cleanliness. 3) Building an intellectually interesting and enjoyable "play path" responds to aesthetic and self-actualization needs. For example, thematic interest can be injected into the physical space of the Learning Trail through history and culture, and the educational intelligence of the environment should be promoted through games. 4) Perfecting the "arrival path" for all age groups is the final sequence for a child-friendly to all-age-inclusive environment. For instance the facility's versatility for the travel needs of diversified groups and the intensive diversity of transition nodes in Learning Trail spaces and activity fields should be considered. This study provides ordered path and scientific references for building Learning Trail spaces in child-friendly neighborhoods. It is conducive to build a child-friendly commuting environment in neighborhood spaces and promote social sustainability.

摘要： 随着“十四五”规划中儿童友好城市建设政策的推进，应通过儿童友好社区学径空间的满意度评价，积极探索其空间环境提升策略。以成都市昭觉儿童友好社区为例，采取半结构化访谈、影像发声法、Kano-AHP模型等方法，建立“行径”安全性、“达径”可达性、“感径”舒适性和“游径”趣味性4个准则层和28个指标层的学径空间友好性标准评价体系。探究用户（3~12岁的儿童及其监护人）和专家不同视角下学径空间各类指标的优先满足序列。得到1）道路整洁度和教育益智性指标因子对用户满意度有显著影响，而生态可持续性与主题趣味性等方面较为重视；2）相较于专家评价权重排序行径安全性>达径可达性>感径舒适性=游径趣味性，用户更重视游径趣味性；3）“构建安全连续行径-配置舒适生态感径-建设益智趣味游径-完善全龄共享达径”的优先序列实施建设。为建设儿童友好社区的学径空间提供了有序途径与科学依据，有助于在社区空间层面为儿童营造友好的通学环境和促进社会可持续发展。
