Ecological Recreation Across the Jinma Mountain Region: A Comprehensive Evaluation of Suburban Mountain Greenway Networks

Investigating the construction of greenway network systems in mountainous suburban areas from an integrated “ecology–recreation” perspective is crucial for promoting the coordinated development of regional multifunctionality. Taking Jinma Mountain in Kunming as a specific case study, this research comprehensively adopts a multivalue, multidimensional perception evaluation method to construct an assessment framework for suburban mountainous greenway networks that couples ecological and recreational functions. The results show that the Jinma Mountain greenway network exhibits a unique “multiple rings intertwined and dense network” pattern, with an optimized density of 0.79 km/km², achieving efficient utilization. Compared to single-function greenways, the network’s ring index (α), connectivity index (β), and cohesion index (γ) have improved by 12.88%, 20%, and 4.19%, respectively, demonstrating a high degree of coupling and coordination. These improvements demonstrate the rationality and scientific rigor of the designed evaluation system, offering significant advantages over traditional single-function greenways. This comprehensive evaluation system not only supplements existing research on greenway networks but also provides a theoretical reference for integrated “ecology–recreation” and sustainable development in mountainous suburban areas.
