Structural Modeling of Heat Mitigation with Green Infrastructure Connectivity in Dense Urban Districts

Abstract

The rapid expansion of global urban areas has exacerbated the urban heat island effect, presenting a severe challenge to public health, energy consumption, and environmental sustainability. While the deployment of green infrastructure has been widely recognized as a viable mitigation strategy, the vast majority of urban planning frameworks treat green spaces as isolated functional units. This study investigates the critical role of spatial connectivity among green infrastructure networks in dense urban districts to optimize heat mitigation. Utilizing advanced structural modeling techniques, this research assesses how continuous ecological corridors influence microclimate variables compared to fragmented green patches. A comprehensive analytical framework is established to evaluate land surface temperatures, ambient air temperatures, and cooling distance decay through simulated urban morphologies. The structural models synthesize variables such as canopy volume, sky view factors, and evapotranspiration potentials across highly densified urban grids. Findings indicate that interconnected green infrastructure configurations enhance the advection of cool air, significantly expanding the spatial extent of the urban cooling island effect. Furthermore, structural connectivity reduces localized heat accumulation by facilitating uninterrupted wind corridors and shading gradients. By providing empirical modeling evidence, this paper underscores the necessity of paradigm shifts in urban environmental design, advocating for continuous green networks rather than isolated aesthetic installations. The insights derived from this structural assessment offer actionable guidance for urban planners seeking to maximize climate resilience in high-density metropolitan regions.
