Whole-region Tourism Greenway Network Organization Mechanism Based on Gravity Model Flow Measurement

This abstract has open access
Abstract Summary
(1) Problem: In the process of the continuous expansion of large cities, the imbalance of urban and rural resources has been brought about. Greenway is an important resource that connects urban and rural areas and combines man-made with nature. It plays an important role in the connection of their environment. The organizational mechanism of greenway network is the core content of Greenway planning. In China, the construction of whole-region tourism has entered a stage of rapid development in urban and rural areas. How to seek the rational use of resources through the combination of whole-region tourism and greenway network planning is the main problem to be solved in this study. (2) Background: At present, the quantitative evaluation of greenway network is mainly focused on discussing the relationship between points and lines in the network. Its organizational methods are mostly based on graph theory, Euclidean distance, connectivity and probability theory. In order to organize the greenway network from the perspective of whole-region tourism, it is necessary to mobilize the industrial, ecological, residential and other resources of cities and towns for coordinated planning. Therefore, the previous quantitative evaluation methods cannot meet the research needs. This study takes Ning'an City as an example. It is an important node town connecting urban and rural areas in both administrative level and spatial environment. At the same time, Ning'an City has a good base of tourism and ecological resources. (3) Reference: This study refers to Greenway Network Planning and organization methods at home and abroad. Based on the literature and research results of gravity model flow measurement, the cost distance formula is improved in greenway network evaluation and organization, and the network flow is allocated to each path through gravity model, so as to enhance the scientificity of the evaluation. (4) Method: The research methods of this paper are as follows. Firstly, the existing greenway network structure of Ning'an City is sorted out and summarized. Then, through the minimum cost path method, the potential greenway network structure is formed based on comprehensive elements and general elements respectively. Through the combination of existing structure and potential structure, a preliminary abstract network structure is formed. Then, gravity model is used to measure and classify the traffic among abstract network nodes. Two kinds of greenway network structures are compared and analyzed based on Synthesis and general elements respectively. On this basis, the structure optimization and network certification of greenway network are carried out through field investigation. (5) General application: Provide reference for the planning and implementation of actual greenway network in urban and rural area of tourist towns.
