我们通过研究生态系统产生效益的机制，并将其与热暴露指标联系起来，提供了一种评估绿色空间热缓解影响的新方法。我们展示了生态系统服务框架如何利用城市绿地生态建模的最先进的供需方法，整合到当前的环境健康研究实践中。我们比较了通过高分辨率蒸散模型指标测量的波士顿冷却生态系统服务供应，以及基于暴露、危害和人口特征的热暴露风险评分测量的冷却效益需求。所得的蒸散发指标遵循与基于植被丰度的传统绿地指标类似的模式，除了在较温暖的地区，如不透水地表水平较高的地区。我们确定了整个波士顿市的供需不匹配区域，其中一些与经济适用房综合体和长期护理设施相吻合。这个新颖的es框架提供了跨学科的方法来优先考虑城市地区，在这些地区，绿色空间干预可以根据与热相关的需求产生最大的影响。
We provide a novel method to assess the heat mitigation impacts of greenspace though studying the mechanisms of ecosystems responsible for benefits and connecting them to heat exposure metrics. We demonstrate how the ecosystem services framework can be integrated into current practices of environmental health research using supply/demand state-of-the-art methods of ecological modeling of urban greenspace. We compared the supply of cooling ecosystem services in Boston measured through an indicator of high resolution evapotranspiration modeling, with the demand for benefits from cooling measured as a heat exposure risk score based on exposure, hazard and population characteristics. The resulting evapotranspiration indicator follows a pattern similar to conventional greenspace indicators based on vegetation abundance, except in warmer areas such as those with higher levels of impervious surface. We identified demand-supply mismatch areas across the city of Boston, some coinciding with affordable housing complexes and long term care facilities. This novel ES-framework provides cross-disciplinary methods to prioritize urban areas where greenspace interventions can have the most impact based on heat-related demand.
