Review On Research Progress Of Greenway In The World

In the world,the theory and application of the Greenway is one of the hot issues of urban planning and ecological protection.Since 1867 Olmsted proposed "park system”,theoretical research of foreign greenway has become a single landscape design to a comprehensive interdisciplinary,in 100 years,.The related greenway construction is gradually transformed from a single linear recreation space into a multifunction and multilayer network system.Thus,the green way is important to solve the contemporary ecological problems and social problems.After 21 Century,the research and construction of green road just unfolding around the world.Greenway as a exotic is introduced to China relatively late,and the theory foundation is weak.In recent years,the foreign greenway theory has not premise of further research and localization,some domestic provinces and cities copy the way of planning and construction way,around the large-scale general suitable construction.so the content of the construction of the science and rationality to be in-depth discussion and research.This paper has combed the research achievements of scholars in China for the past 30 years,and put forward some thoughts on research and construction of China.The introduction part first introduces the research background,purpose and research methods.First,using bibliometrics method on the greenway status research,its characteristics summarized as three research levels(theoretical research,empirical research,application design),1 + 4 subject structure(landscape arc hitecture and urban planning,architecture,ecology,forestry)and six hot spot to composite function,planning and design,urban and rural,tourism development,urban greenway,transportation system).Secondly,using sample data characteristics and attention degree map analysis combined approach,the domestic research process is divided into three stages: the germination period(concept),the initial growth period(explore the formation and practice of theory of Greenway system),the rapid growth period(P RD regional greenway network construction and national Greenway movement).Finally,through the discussion of the different stages research and hot,founding the greenway research focus,namely urban greenway coupling of four main research direction(multifunctional greenways planning,urban and rural planning theory research,greenway function of tourism development and management,green road and traffic system)were introduced in detail.After summarizing and thinking,to ensure the healthy development of domestic greenway,greenway should update the traditional concept of the transition from "Tao" to "ecological network system",and using elastic landscape,green infrastructure,ecological network,landscape ecology and other related theory to perfect the theory of Greenway foundation;the status and demand of national policy,optimize and upgrade of Green Road,development mode to form a multi-level,systematic,green road construction to promote economic backward areas;planning ways and means of the greenway is improved by means of elastic and big data technology,the green road construction activities more scientific and the times;perfect organization,perfect laws and regulations,the Greenway Construction Law,and effectively improve the participation of the people of the green road construction and management.
