城市生态基础设施评估模型、管理模式与调控方法研究

城市生态基础设施指为人类生产和生活提供生态服务的自然和人工设施，保证自然和人文生态功能正常运行的公共服务系统，是社会赖以生存发展的基本物质条件，包括自然生态设施与具有生态服务的人工建设用地。目前我国缺乏城市生态基础设施的基础理论、技术体系与管理方法研究。与生态基础设施密切相关的城市热岛效应、灰霾效应、水体污染和城市内涝等问题已成为制约城市可持续发展的主要瓶颈之一。本项目以城市生态基础设施管理问题为研究对象，主要运用生态系统服务InVEST评估模型、生态系统管理、遥感和GIS空间分析等多学科综合方法，辨识城市生态基础设施结构与功能的生态耦合关系与作用机制，建立城市湿地和绿地生态基础设施的系统评估模型、格局优化与适应性生态系统管理方法，提出城市地表硬化的复合生态效应评估与生态工程改造方法，最后提出基于生态系统服务的城市生态基础设施的综合管理模式与系统调控方法,并在北京、常州和淮北进行实证研究。

Urban ecological infrastructure, including natural ecological facilities and artificial construction land with ecological services, is the basic material conditions for human survival and development and could provide ecosystem services to human life and ensure the natural and cultural functions under normal working conditions. At present, the basic theories, technology system and management methods about urban ecological infrastructure were lacking in our country. Moreover, various of urban environmental problems related to ecological infrastrudture such as urban heat island effect, gray haze effect,water pollution and urban flood have become bottlenecks restricting urban and regional sustainable development. This project aims to study the urban ecological infrastructure management issues using InVEST model for ecological services, ecosystem management methods, remote sensing and GIS sptial analysis techniques and other multi-disciplinary comprehensive methods. This research will analyse the coupling relationship and mutual mechanism between the structure and functions of urban ecological infrastructure, establish evaluation methods for wetland and green space ecological infrastructure services of cities, pattern optimization methods and management models, put forward the ecological reconstruction and design methods for urban soil sealing in the city. Finally, the comprehensive management pattern and systemetic regulation approach based on ecosystem services for urban ecological infrastrucure will be advanced and the case studies will be applied in Beijing, Changzhou and Huaibei cities.
