基于水生态系统服务综合效能提升的城市河流生态修复研究

针对城市双修背景下河流生态修复工作存在的3大误区与困境，通过荟萃分析的文献定量研究，厘清了城市河流修复的生态效应，指出河流生态修复对水生态系统服务有着积极的提升作用，丰富物种多样性，增加物种数量与分布密度，对调节性生态系统服务有显著的正面影响。研究构建了城市河流生态修复方面，水生态系统服务综合效能提升的概念模型，包括以水质净化为基础、生境多样性为核心、文化性服务为关键的3个方面。

Urban River Ecological Restoration Based on Improving the Overall Capacities of Water-relatedEcosystem Services

There are three major misunderstandings and difficulties regarding urban riverecological restoration in the context of urban renovation and restoration. Using a meta-analysis,this paper aims to clarify the ecological effects of urban river restoration through quantitativeliterature research. The results showed that urban river ecological restoration positivelycontributed to water-related ecosystem services. It can also increase the richness of riverbiodiversity, species number and density, which have significant positive impacts on regulatingecosystem services. This paper also proposes a framework for the ecological restoration ofurban rivers through which the overall capacity of water-related ecosystem services can beimproved. The framework includes three aspects, which were water quality improvements asthe foundation, habitat diversity as the core, and cultural service as the key.
