| Since 2010,the General Office of the Guangdong Provincial Committee and the General Office of the Guangdong Provincial People’s Government have issued the "Opinions on the Implementation of Livable Urban and Rural Areas".The Pearl River Delta region has taken the lead in building six regional greenways in series with more than 200 development nodes such as major forest parks,nature reserves,scenic spots,country parks,waterfront parks and historical and cultural relics,which constitute the main body of the Pearl River Delta greenway network.Frame.After nearly 10 years of development in the Pearl River Delta region,waterfront greenway Construction has been continuously improved and perfected.As an important part of waterfront greenway,waterfront trail has also been a good opportunity for upgrading and transformation.This paper takes the waterfront trails space as the breakthrough point,aiming at further exploring the design method of waterfront trails space.Based on the quantitative research of waterfront trail in China is still in its infancy,the author tries to explore the suitable quantitative index range of waterfront trails space by using spatial syntactic analysis.By combining theoretical and case studies,the author chooses the waterfront landscape of Guangzhou,Foshan,Shenzhen three places.Four urban waterfront greenbelts with good view resources,abundant types of trails and wide radiation range were investigated.The four urban waterfront greenbelts were compared and analyzed qualitatively and quantitatively.On the qualitative level,the elements of the trails,spatial sequence,spatial interface and plant allocation were analyzed in depth,trying to find the commonness and characteristics of the cases,and pointing out the existence of the cases.The inadequacies and some references lay the foundation for the design strategy.On the quantitative level,spatial syntax is used to quantitatively analyze the global integration degree,integration degree and selectivity degree under different topological radius and asynchronous row radius,and intelligence degree.The potential meaning and logical relationship of spatial syntax in the spatial design of waterfront trails are explored,and quantitative conclusions and viewpoints are drawn,which enhances the scientificity of previous planning and design.According to the systematic combing of the related theories of trails space and space syntax,and combined with the relevant conclusions of the case,the general principles and design strategies of waterfront pavement space design are summarized.Finally,through the design strategies of macro,meso and micro levels to guide the preliminary design of theYayao River landscape belt in Zengcheng,Guangdong Province,the functional layout and the high correlation between dynamic and static zoning and the distribution of integration degree are discussed quantitatively by using spatial syntax at macro level,and the high-low spatial integration ratio of main landscape nodes is verified to be in line with the syntactic quantification.The reference standard guides the planning and design of the type of pavement,vertical,interface and node facilities at the meso and micro levels,which reflects the applicability of the strategy.To sum up,this paper summarizes a set of design principles and Strategies of waterfront trails space by combining qualitative and quantitative methods,hoping to provide more syntactic quantitative reference and new ideas for the early design of waterfront trails space,so as to better improve the quality of urban waterfront green walkway construction in the Pearl River Delta region and even in the whole country. |
