城市绿色基础设施空间形态的GIS生态服务评价模型

GIS-based Eco-services Evaluation Model for Evaluating the Physical Form of Urban Green Infrastructure

借助GIS数据分析模型,构建以生态服务为核心价值的城市绿色基础设施的客观评价方法。基于Birkeland的"提供生态服务的正开发"理论,提出绿色基础设施是一种能提供生态服务的有效途径。从绿色基础设施所能够提供的两大与植被有关的生态服务——生物多样性的支持与碳调节出发,以上海临港新城为基地展开研究,创立易于操作、直观的生态服务效能评价的计算机方法技术,即GIS生态服务评价模型(GEEM),通过对十二大生态因子的研究,阐述生态服务效能与城市绿色基础设施空间形态的耦合机理,对进一步优化城市绿色基础设施的空间形态起到积极引导的作用。

This paper aims to build an objective evaluation method that centers on the provision of eco-services and is based on GIS analysis model. Based on the theory of Positive Development through the provision of eco-services, this paper proposes green infrastructure is an effective approach to provide eco-services. It discusses two vegetation eco-services, namely supporting biodiversity and regulating carbon, and their provision via green infrastructure. Lingang New City in Shanghai is studied as the case. The GEEM is proposed as a practical and effective method to evaluate the provision of eco-services. It discusses twelve parameters and clarifies the relationship between physical form of green infrastructure and the provision of eco-services, based on which the strategies for physical form are proposed as a conclusion.
