| 绿道在改善城市生态环境、提升人居环境品质、增
强城市居民福祉和推动城市高质量发展等方面具有重要作用。
中国开启绿道建设已逾10年，开展对已建成绿道供给水平的
综合评价，将有助于全面掌握绿道供给水平现状，进而为未来
绿道优化建设提供科学指导。从生态保护、交通连接和休闲游
憩3个层面，采用层次分析法构建绿道供给水平评价体系，以
南京市主城区已建成绿道为例，基于实地调查数据和网络大数
据，按照“单因子-多因子-总体”的思路测度和评析绿道供
给水平的空间分布特征，并依据现存问题，提出了连接生态斑
块、构建生活圈绿道循环系统、完善内部服务设施等5项针对
性的优化策略。 |

| Abstract: |
| Greenways play an important role in urban ecological
and living environment, the well-being of residents, and highquality
urban development. As China has been implementing
greenway construction for over 10 years, carrying out a
comprehensive evaluation of the supply level of built greenways
will help to understand the overall current condition of greenway
supply, identify existing problems, and provide scientific guidance
for future greenway construction. Taking the built greenways in
main urban area of Nanjing as an example, this study proposes
an applicable evaluation system from three aspects: ecological
protection, transportation connection, and leisure and recreation,
using Analytic Hierarchy Process. Based on on-site and online
data, the spatial distribution characteristics of greenway supply
level are evaluated under the process of "single factor, multi factor
and overall". Then based on existing problems, five targeted
optimization strategies are proposed, including connecting
ecological patches, building a greenway circulation system for life
circle, improving internal service facilities, etc.. |
