| Under the background of rapid urbanization,the construction and development of urban ecological environment face many problems.At the same time,with the economic development and the improvement of living standards,people’s demands for the quality of living environment and material culture are increasingly prominent.Urban greenway is an urban open space with multiple functions including ecological restoration,historical and cultural protection,and landscape construction.It is an important way to solve current urban problems.At present,the exploration and practice of greenway networks at home and abroad are mostly concentrated in the region or city area,and there are few studies on the central urban areas where construction activities are concentrated.The built-up environment in the central urban area of Bozhou is dense.In the process of rapid urbanization,land and space resources are increasingly tight.It is urgent to fully integrate various landscape resources to highlight the functional diversity of urban greenways and the characteristics of public spaces to meet people multiple needs.This study focuses on the central urban area of Bozhou,taking greenway elements and related systems as research objects,and analyzing relevant concepts and theories,clarifying the specific connotation of greenway is to be able to effectively connect various natural,humanistic and park green spaces within the urban area.The network-like open space formed by resources and other points of interest is an important way to protect the traditional style and sustainable development of the city and improve the urban environment.Secondly,it combs the relevant theoretical research and practical cases at home and abroad,clarifies the construction elements,construction system,data sources and processing methods of the greenway network in the downtown area of Bozhou,providing technical support for further quantitative research.Then,it analyzes the natural geographical conditions,social and human conditions and related planning of the central urban area of Bozhou,combined with the field investigation of the existing green roads,in-depth research on the current status and existing problems of the green road construction in the central area of ? ?Bozhou,and lays the foundation for further research.The focus of this study is to build a green road network suitability index systemwith Bozhou central urban characteristics,and a method based on the construction process,combined with the status quo of green road construction development in Bozhou central urban areas to build a systematic and multifunctional green road network.Based on the theoretical and practical research results,the construction principles of the greenway network in the central urban area of Bozhou were put forward,and combined with the greenway network structure,the index system framework of greenway suitability evaluation was established from the two levels of nodes and lines.Among them,the node-level indicators mainly include four types:natural ecology,leisure and recreation,history and culture,and life services;the line level is mainly evaluated from four aspects: connectivity,landscape,service,and ecology of the connection path.The core research ideas are: to determine the classification of various types of nodes according to quantitative standards and relevant regulations;based on the analytic hierarchy process and expert consultation method to clarify the weight indicators of the main line elements;combined with cost connectivity,cost distance analysis and related planning and greenway The construction situation revises the greenway network construction result;then analyzes the greenway network structure index,and uses this to verify the optimization effect of the construction result on the greenway network system in the central urban area of Bozhou.In order to scientifically and effectively implement and operate the results of the construction of the greenway network in the central urban area of Bozhou,this paper proposes corresponding strategic suggestions from the two levels of specific planning,design and operation management.The first is the level of planning and design.This article puts forward suggestions from the aspects of construction principles,different types of route design strategies,junction space and functional design to support service facilities.The second is the operation management level.This article mainly puts forward suggestions on policy support,capital guarantee and diversified management,market-oriented operation with multi-party participation,and greenway brand building.Figure [62] table [20] reference [83]... |
