Eco-DRR（基于生态系统的灾害风险减少）作为替代“灰色”或已建基础设施的基础设施，因其引进和维护成本低、提供各种生态系统服务和地方社区发展等吸引人的特点而备受关注。另一方面，灰色基础设施仍然是减少灾害风险的一个核心措施，因为人们对其设计和抵御自然灾害的功能有着全面的了解。关于在减灾的许多方面使用绿色基础设施而不是灰色基础设施的争论提出了一个重要的问题：在什么情况下绿色基础设施更可取？本文采用理论方法，提供了一个确切的条件下，引入绿色基础设施是可取的，考虑到方面的不确定性，推导出最佳规模的绿色基础设施和灾害风险（或预期的损害）。在最佳的绿色基础设施，我们显示了一个确切的水平的人口，在此情况下，使用生态DRR是最好的灰色基础设施，表示的参数，反映的概率发生的危害，防止暴露于危害的概率，人口规模，和脆弱性的损害累积暴露，以及成本和收益的两个基础设施。我们的研究结果提供了有用的信息，政策决策是否采用灰色或绿色基础设施在一个地区，通过应用结果，以各种情况下，通过假设参数的确切值。
The Eco-DRR (ecosystem-based disaster risk reduction) is attracting attention as infrastructure that substitutes “gray” or built infrastructure, owing to its attractive characteristics such as lower costs of introduction and maintenance, provision of various ecosystem services, and local community development, among others. On the other hand, gray infrastructure is still a central measure of DRR, as there is a comprehensive understanding of its design and functioning against natural hazards. The argument about the use of green infrastructure instead of gray infrastructure in many aspects of DRR raises an important question: under what circumstances is green infrastructure more desirable? This paper uses a theoretical approach to provide an exact condition under which introducing green infrastructure is desirable, taking into consideration the aspect of uncertainty in deriving the optimal size of green infrastructure and the disaster risk (or expected damage). Under optimal green infrastructure, we show an exact level of the population, under which using Eco-DRR is preferable to gray infrastructure, expressed by parameters reflecting the probability of occurrence of hazard, probability of preventing exposure to the hazard, population size, and vulnerability to damage accruing from exposure, as well as costs and benefits of the two infrastructures. Our results provide useful information regarding policy decision-making about whether to adopt gray or green infrastructure in an area, by applying the results to various cases by assuming the exact values of the parameters.
