Research On Planning And Design Of Community Greenways In Shallow Mountain Area Of Beijing

With the development of economy and the increase of population,Beijing's urban construction is spreading to the surrounding mountainous areas.As a transitional area between deep mountain area and plain area,shallow mountain area is facing a strong demand for land development,undertaking more human activities,and its ecological environment and human settlement environment are affected to a certain extent.Greenway has the functions of connecting ecological patches,integrating green space,protecting historical and cultural heritage,providing residents with green travel environment and promoting the development of local industrial economy.It is one of the ways of rational land use development in shallow mountainous areas.In the greenway network system,community-level greenway is most closely related to the daily life of residents,which can create a beautiful living environment for local residents while taking into account the ecological environment protection in shallow mountainous areas.This paper reviews the research status of shallow mountain area and community-level greenway,and summarizes the related concepts of shallow mountain area and community-level greenway.Through the study of relevant cases,this paper explores the planning and design methods that can be used for reference,and expounds the planning and design concept and principles of community-level Greenway in shallow mountain areas of Beijing.Taking Yanqi Town in Huairou District of Beijing as an example,the research process and results are as follows:(1)Combing the basic conditions of Yanqi Town,selecting nine influencing factors of elevation,slope,slope direction,roads,villages,available sites,streams and ravines,ornamental spots and industries,and using land suitability evaluation in GIS geographic information analysis platform to get the appropriate planning scope.(2)Construct the greenway network,carry out zoning planning,and plan the difficulty of the tour route and the greenway post station.(3)Special planning for a high-suitability area and landscape design for high-grade patches.
