城市绿色空间旨在抵消温室气体（GHG）排放，去除空气和水污染物，冷却当地气候，改善公众健康。为了利用这些服务，各市政当局集中努力在城市环境中设计和实施基于生态系统服务的“绿色基础设施”。在某些情况下，这种基础设施的环境效益已得到很好的记录，但这些效益往往不明确，没有量化，和/或被潜在的成本所抵消。量化城市绿色基础设施中的生物地球化学过程可以提高我们对设计的城市绿色空间所产生的城市生态系统服务和损害（负面或意外后果）的理解。在这里，我们提出了一个框架，以集成生态地球化学过程的设计，实施和评估的净效益的绿色基础设施，并提供例子，温室气体减排，雨水径流缓解，并改善空气质量和健康。
Urban green space is purported to offset greenhouse-gas (GHG) emissions, remove air and water pollutants, cool local climate, and improve public health. To use these services, municipalities have focused efforts on designing and implementing ecosystem-services-based “green infrastructure” in urban environments. In some cases the environmental benefits of this infrastructure have been well documented, but they are often unclear, unquantified, and/or outweighed by potential costs. Quantifying biogeochemical processes in urban green infrastructure can improve our understanding of urban ecosystem services and disservices (negative or unintended consequences) resulting from designed urban green spaces. Here we propose a framework to integrate biogeochemical processes into designing, implementing, and evaluating the net effectiveness of green infrastructure, and provide examples for GHG mitigation, stormwater runoff mitigation, and improvements in air quality and health.
