Research On The Green Road System Planning Of Beijing Tianjin Hebei Urban Agglomeration

Greenway is a series of natural and cultural landscape resources,which is suitable for the linear green space of walking,cycling,etc.Urban greenway network refers to rely on is located in the city proper chunks of forest land,water,fields and villages around the building corridor,will focus on urban and rural scenic areas,nature reserves,forest wetland park in series with the exchange of the ecological network system and form ecological elements.Due to large scale urban agglomeration,it has an important position in national development,research and construction of challenging,but the greenway system as an important part of urban ecological system,the research is of great significance to the coordinated development of urban agglomeration area,so this article chooses the Beijing-Tianjin-Hebei urban green system as the research object.With the rapid development of economy and urbanization,the urban ecological environmental problems continuously emerging,regional harmonious development problems become the focus of the attention,how to guarantee the rapid economic development at the same time,protect the ecological environment to the survival of people become a problem to be solved.In Beijing-Tianj in-Hebei urban green system as the research object,aiming at the sustainable development of ecological environment,on the basis of regional planning,ecological network,landscape ecology and other relevant theory,the integrated use of comparative analysis and GIS spatial analysis methods,study of Beijing-Tianjin-Hebei urban green system planning.Main contents and conclusions:1)through the analysis of the theory and practice of greenway system at home and abroad,this paper puts forward the research method and framework of this paper;2)in the region of the comprehensive consideration within the scope of all kinds of resources and environment,urban layout,the related policy planning elements,on the basis of the importance of each factor by Delphi expert grading method for weight assignment,get the greenway concept of quantitative evaluation of urban green road line selection model;3)using GIS analysis to establish buffer zones for each element,and then weighted superposition of each element with superposition analysis to obtain the suitability evaluation result of green road selection in urban agglomeration;4)in the city green way based on the results of suitability evaluation,put forward the waterfront landscape,mountain ecological greenway,leisure culture,bashang grassland forest greenway four types,including 7 main green road line selection of Beijing-Tianj in-Hebei green system planning layout;5)from the slow road,landscape,service facilities,marking system from five aspects of Beijing-Tianj in-Hebei urban agglomeration,the integration of green way special facilities are studied,and the green way implementation mechanism and safeguard measures are proposed.Based on the evaluation of space suitability,this paper provides a new way of thinking for green channel selection by using quantitative analysis method.In the planning of greenway system,the reasonable utilization rate of the belt and linear space with low utilization rate can better save the increasingly stressed urban resources,thus effectively protecting the ecological environment of urban agglomeration.
