To address the key issues in the evaluation of the aesthetic and cultural functions of commonly used colorful foliage tree species in southern China (focusing on Guangzhou, Shenzhen and Foshan cities in the Pearl River Delta), the authors initially constructed a system of evaluation indicators with 3 criterion layers (B1–3), 9 subcriteria layers (C1–9) and 27 indicator layers (D1–27) and established a comprehensive indicator method, based on literature combing and theoretical practice, the method of expert evaluation (Expert Survey Method) and the principle of hierarchical analysis. The paper mainly aims to effectively evaluate the aesthetic and cultural functions of the colorful leaf forests in the Pearl River Delta, to clarify the key points of conservation and development of cultural ecosystem services in the forest city agglomeration, to enhance the compatibility and practicality of colorful forest construction technology with the construction of a beautiful bay area, and to expand the theoretical connotation and application technology of urban forestry and human habitat.

针对珠三角城市群中广州、深圳、佛山等地及周边地区常见的彩叶树种美学文化功能评价中的关键问题, 在文献梳理和理论实践的基础上, 运用专家评估法和层次分析原理建立综合指标法, 构建包括3个准则层(B1~3)、9个次准则层(C1~9)和27个指标层(D1~27)的评价指标体系, 以期有效地评价珠三角彩叶林的美学与文化功能, 明确森林城市群生态系统文化服务保护与开发的重点, 提升彩色林相营建技术与美丽湾区建设的匹配性与实用性, 拓展城市林业和人居环境学科理论的内涵与应用。
