基于扎根理论的“G-LEF”复合型绿道分类方法研究

Research on"G-LEF"Compound Greenway Classification Method Based on Grounded Theory

科学的绿道分类有助于系统认知绿道的基本特性,并有效指导绿道的规划设计与建设。既有绿道分类方法多因由主观诉求主导而产生分类不明、重复分类等问题,进而造成绿道设计与建设中的形式主义、“千道一面”、关系混乱及未成系统等现象。文章通过梳理绿道相关导则与文献,对现有绿道分类现状和问题进行分析,采取扎根理论,以级别(Grade)、区位(Location)、要素(Element)及功能(Function)为分类依据,提出“G-LEF”复合型绿道分类方法,以期为绿道的规划、建设与管理提供科学依据。

Current classification methods of greenways are miscellaneous and subjective and may mislead the design and construction of greenways into formalism,similarity,and lack of systematization.A rational classification may help people’s cognition of greenway characters and guide the planning and construction of greenways.Based on a review of relevant literature and regulations,the paper makes an analysis of status quo and problems of greenway classification,extracts the four classification bases of grade,location,element and function under the guidance of the grounded theory,puts forward a greenway classification method based on"G-LEF"compound(grade,location,element,function)from grounded theory,in order to provide a scientific basis for greenway planning,construction and management.
