Designing Of Typital Design Pattern Of Greenway In Pearl River Delta City Group

The international greenway movement originated in 80 years of 20th and the European ecological network organization established in 2000 promote the domestic development of greenways. In 2009, the Pearl River Delta (above referred to as PRD) using of the urban linkage, following the basic principles of ecological, localization, diversity and humanity, has built a regional greenway. In this paper, basing on research and case design, regarding regional greenway of the Pearl River Delta city g as study object, generalizing the theory of greenway planning and design, according to the Classification of "Regional Greenway Of Pearl River Delta Planning and Design Technical Guidelines", analysising of the greenway building elements of the Pearl River Delta Green Road, desiged10 typical types of design patterns. This outcome expectations contribute to theoretical innovation of the greenway and planning practices.In this paper, having a systematic research study and the sort on greenway, summed up theories of the design of greenway such as patch -matrix - corridor, landscape ecological flow, edge effects, ecological succession, plant science, animal behavior, safety Distance, Recreation, Public green space service radius theory. And greenway design theory applied to the actual case design.Basing on the existing types of classification of the Pearl River Delta, according to the main functional characteristics of ecological greenways, country-based Green Road, Green Road, refinement in the class of ten greenway. The classification system of greenways which based on the Location of greenway (categories) - the main function of greenway (in class), is conducive to the construction and management, can also serve as the main basis for design of the greenway.Through the field research and analysis of been built greenway in Pearl River Delta, making systematic review and analysis of the basic building elements of greenway in the Pearl River Delta city group greenway, described natural elements and artificially constructed elements of greenway.On the location of classification system about the Location of greenway (categories) - the main function of greenway (in class), selecting typical types of greenway in Pearl River Delta city group, having focus of location and functional characteristics of the biological pathways based greenway, the embankment type of water source protection greenway, Country channel type, country and other 10 types greenway, according to location and functional characteristics, firstly pose the most typical design patterns of the Pearl River Delta Greenway.
