城市绿地生态网络概念辨析及构建方法探析

Exploring the Conceptual Analysis and Construction Method of Urban Green Space Ecological Network

中国城市建设在近50年取得了辉煌成就,但快速城市化过程也导致了生境破碎、生物多样性下降、生态系统服务功能低效等问题。在国土空间生态保护修复和城市高质量转型发展背景下,城市绿地生态网络的建设对提升生态系统服务功能及构建城市生态安全格局具有重要意义。研究旨在辨析城市绿地生态网络的概念及内涵,总结城市绿地生态网络的主要特征,梳理其发展历程,提出城市绿地生态网络主要构建方法;同时,明确其作为应对城市生态环境胁迫和挑战的重要途径之一,及未来发展的主要方向。以期进一步完善城市绿地生态网络理论,为中国城市绿地网络建设提供参考。

China's urban construction has made brilliant achievements in the past 50 years,but the process of rapid urbanization has also led to problems such as habitat fragmentation,decline of biodiversity,and inefficient ecosystem service function.In the context of ecological protection and restoration of national land space and high-quality transformation and development of cities,the construction of urban green space ecological network is of great significance to the enhancement of ecosystem service function and the construction of ecological security patterns.The main purpose of this paper is to identify the concept and connotation of urban green space ecological network,summarise the main features of urban green space ecological network,sort out the development history of urban green space ecological network,and put forward the main construction methods of urban green space ecological network.At the same time,as one of the important ways to cope with the urban ecological environment coercion and challenges,the main direction of the future development of urban green space ecological network is clarified.The results of the study are intended to further improve the theory and provide a reference for the construction of urban green space network in China.
