Green infrastructure is an increasingly popular strategy to simultaneously address challenges associated with urbanization and global environmental change, including increased flooding and rising temperatures. While many cities aim to expand green infrastructure to deliver ecosystem services, their impacts will be limited without significant uptake on private property. Most studies and programs to date focus on public land, so little is known about what would motivate private residents to implement green infrastructure. This study addresses this gap, combining household survey and spatial data from the Phoenix metropolitan region in Arizona by examining what factors predict green infrastructure implementation, with a particular focus on flooding and heat risks. The results suggest that residents are generally aware of their relative exposure to these hazards, but their risk perceptions do not translate into increased implementation of green infrastructure. Prior experience of flood damage is a predictor of stormwater infrastructure implementation, but experience with heat did not impact planting vegetation to mitigate the effects of extreme temperatures. Instead, the decision to implement green infrastructure is likely constrained by limited capacity based on income and homeownership, which can impede people’s ability to make management decisions on private residential property. More research is needed to unpack the seemingly complex factors that shape residents’ decisions to implement green infrastructure on their property.

绿色基础设施是一种越来越受欢迎的战略，可以同时应对与城市化和全球环境变化相关的挑战，包括洪水泛滥和气温上升。虽然许多城市旨在扩大绿色基础设施以提供生态系统服务，但在不大量占用私有财产的情况下，其影响将是有限的。迄今为止，大多数研究和计划都集中在公共土地上，因此对于促使私人居民实施绿色基础设施的动机知之甚少。这项研究通过检查哪些因素预测了绿色基础设施的实施，特别是洪水和热风险，结合了住户调查和亚利桑那州凤凰城大都会地区的空间数据，解决了这一差距。结果表明，居民通常都知道他们相对容易受到这些危害，但是他们的风险感知并不能转化为绿色基础设施实施的增加。先前的洪水破坏经验是实施雨水基础设施的预兆，但是高温的经验并没有影响种植植被以减轻极端温度的影响。取而代之的是，实施绿色基础设施的决定可能受到基于收入和房屋所有权的有限能力的约束，这可能会阻碍人们对私人住宅物业做出管理决定的能力。需要做更多的研究来揭示看似复杂的因素，这些因素影响着居民在其财产上实施绿色基础设施的决策。但是他们的风险感知并不能转化为绿色基础设施实施的增加。先前的洪水破坏经验是实施雨水基础设施的预兆，但是高温的经验并没有影响种植植被以减轻极端温度的影响。取而代之的是，实施绿色基础设施的决定可能受到基于收入和房屋所有权的有限能力的约束，这可能会阻碍人们对私人住宅物业做出管理决定的能力。需要做更多的研究来揭示看似复杂的因素，这些因素影响着居民在其财产上实施绿色基础设施的决策。但是他们的风险感知并不能转化为绿色基础设施实施的增加。先前的洪水破坏经验是实施雨水基础设施的预兆，但是高温的经验并没有影响种植植被以减轻极端温度的影响。取而代之的是，实施绿色基础设施的决定可能受到基于收入和房屋所有权的有限能力的约束，这可能会阻碍人们对私人住宅物业做出管理决定的能力。需要做更多的研究来揭示看似复杂的因素，这些因素影响着居民在其财产上实施绿色基础设施的决策。但是受热的经验并没有影响种植植被以减轻极端温度的影响。取而代之的是，实施绿色基础设施的决定可能受到基于收入和房屋所有权的有限能力的约束，这可能会阻碍人们对私人住宅物业做出管理决定的能力。需要做更多的研究来揭示看似复杂的因素，这些因素影响着居民在其财产上实施绿色基础设施的决策。但是受热的经验并没有影响种植植被以减轻极端温度的影响。取而代之的是，实施绿色基础设施的决定可能受到基于收入和房屋所有权的有限能力的约束，这可能会阻碍人们对私人住宅物业做出管理决定的能力。需要做更多的研究来揭示看似复杂的因素，这些因素影响着居民在其财产上实施绿色基础设施的决策。
