绿色基础设施雨污管理规划研究进展

传统雨水和污水管理基础设施的弊端在高速城市化进程下日益显现,绿色基础设施已被认为是更具可持续性的、理想的替代设施.从目标制定、设施类型选择、所选设施数量及规模确定、选址和绿色基础设施网络优化5个方面对绿色基础设施规划于雨水和污水管理领域的已有研究进行了总结,分析不足和未来研究方向.鉴于难以量化绿色基础设施收益限制了相关规划研究的发展,指出通过跨学科、多部门合作,建立水文生态耦合模型探究水文过程和生态过程交互机制是支持绿色基础设施提供水文、生态和社会综合效益的量化研究的可行途径.阐述了分别从设施尺度和网络尺度进行完整的绿色基础设施规划研究的必要性,明晰了景观格局优化是在设施尺度研究的基础上进行绿色基础设施网络优化以保障并提升绿色基础设施功能的技术路线,指出对绿色基础设施的规划研究应逐渐由雨污管理功能延伸至社会生态系统中兼顾生态环境和社会经济视角的多项生态系统服务的提供.

Planning Research on the Green Infrastructure in the Stormwater and Wastewater Management:A Review

The weeknesses of traditional stormwater and wastewater management infrastructures are gradually increasing in the process of rapid urbanization,green infrastructure has been considered as a more sustainable and ideal alternative.The existing researches on green infrastructure planning in the field of stormwater and wastewater management from five aspects: targets formulation,facility type selection, number and scale determination of alternative facilities,site selection and green infrastructure network optimization are summarized,the deficiencies and future research directions as well.The development of related planning research is impeded by the complexity in quantifying the benefits of green infrastructure,threfore the feasible pathway that the establishment of hydroecology coupling models through interdisciplinary and multi-departmental cooperation which explore the interaction mechanism of hydrological processes and ecological processes and support the quantitative research of hydrological,ecological and social comprehensive benefits provided by green infrastructure is pointed out.The necessity of conducting a complete green infrastructure planning research from facility scale to network level respectively is stated.The landscape pattern optimization based on facility scale research as the technical route for green infrastructure network optimization that ensure and enhance the functions of green infrastructure is narrated.The fact that the research field of green infrastructure planning ought to expand to the supply of various ecological services that cover both nature and social perspectives in social-ecology system from the management of stormwater and wastewater management gradually is expounded.
