城市地区面临着一些环境问题，包括过度的热应力和温室气体和污染物的集中排放。在过去的几十年里，许多缓解战略已经设计和实施，以抵消这些问题，改善城市的环境质量，这可以大致分为白色，绿色或蓝色基础设施。城市减缓战略的运作和效力涉及景观动态、人类活动和大气传输之间的复杂相互作用，这会导致复合而不是单一的环境影响。在这项研究中，我们进行了一个严格的审查的复合环境影响的城市缓解战略，并评估，除了有针对性的冷却效果，由此产生的共同利益，权衡，或意想不到的后果，在建筑节能，空气质量的改善，碳排放抵消，对人类健康的影响。此外，我们提出了一种新型的数学框架，能够以统一的方式评估复合环境影响，并给出了一些初步结果作为概念验证。确定了一些知识差距，要求未来的跨学科协同作用之间的城市工程师，大气和气候科学家，流行病学家。
Urban areas confront a number of environmental issues including excessive thermal stress and concentrated emissions of greenhouse gases and pollutants. In past decades, many mitigation strategies have been designed and implemented to counteract these issues and ameliorating the environmental quality in cities, which can be broadly classified as white, green or blue infrastructure. The functioning and efficacy of urban mitigation strategies involve complex interactions between landscape dynamics, anthropogenic activities, and atmospheric transport, which leads to compound, rather than singular, environmental impacts. In this study, we conducted a critical review of the compound environmental impact of urban mitigation strategies, and evaluated, besides the targeted cooling effect, the resultant co-benefits, trade-offs, or unintended consequence, in terms of building energy saving, air quality improvement, carbon emission offset, and impact to human health. Furthermore, we proposed a novel mathematical framework that is capable of assessing the compound environmental impact in a unified way, together with some preliminary results as the proof-of-concept. A number of knowledge gaps are identified which calls for future transdisciplinary synergy among urban engineers, atmosphere and climate scientists, and epidemiologists.
