基于城市生态廊道概念应用的三个衍生概念生成与辨析

Generation and Analysis of Three Derived Concepts Based on the Application of Urban Ecological Corridor Concept

城市生态廊道建设是国土空间规划体系下城市生态空间规划落地实施的重要途径。生态要素及廊道概念的界定、研究对象及研究层级的梳理、生态廊道功能的定位是当前城市生态廊道研究中的关键问题。在梳理城市生态廊道相关概念演化发展的基础上,提出了3个新概念——城市生态空间廊道、城市绿地生态廊道及城市复合生态廊道,阐述概念产生的背景、内涵和外延层面的差异性及概念衍生的必要性,聚焦概念辨析、要素明晰、地类衔接、规划对接、管控实施等方面,为国土空间规划体系下市域层面的生态空间规划、功能分区和用途分类衔接、复合生态空间管控等提供理论基础。

The construction of urban ecological corridors is an important way in the implementation of urban ecological space planning under the territorial space planning system.The definition of ecological elements and corridor concepts,the carding of research objects and levels,and the positioning of ecological corridor functions are the key issues in the current urban ecological corridor research.Based on the analysis of the related concepts of urban ecological corridor,three derived concepts-urban ecological space corridor,urban green space ecological corridor,and urban composite ecological corridor-were proposed in this paper.Then,the paper expounded the background of the new concepts,discussed the differences of three new concepts in the connotation and extension levels,and the necessity of putting forward the concepts.This paper mainly focused on the concept identification,element clarity,land type convergence,planning docking,and management and control implementation,so as to provide reference for the ecological space planning,functional zoning and land use classification convergence,and composite ecological space management and control at the city level under the territorial space planning system.
