“…In the least-cost distance model, the existing green space patches with suitable ecological functions constitute the network source points, forming the ecological function flow diffusion and maintaining the ecosystem balance [32]. The basic definition of the widely used landscape connectivity theory was mainly proposed by Taylor et al Landscape connectivity is the degree of promoting or hindering the movement of organisms between source patches in a certain ecological process, forming a network in the mode of resource nodes and corridors [33]. In the process of landscape connection, landscape resistance refers to the influence of elements on ecological flow rate, and the resistance increases with the increase of the frequency of crossing various landscape boundaries [33,34].…”

In the process of landscape connection, landscape resistance refers to the influence of elements on ecological flow rate, and the resistance increases with the increase of the frequency of crossing various landscape boundaries [33,34]. It can be seen that the theory of landscape connectivity is to explore the organic relationship between similar patches or heterogeneous patches in the process of function and ecology [34].…”

The ecological value, cultural value, economic value and industrial value of the county space, where a variety of human activities and natural ecological processes are carried out, act as the key elements considered in county spatial planning. However, there is a lack of carrying space for integrating these values in the actual Chinese county construction. In this article, the construction of a county greenway network is based on multiple needs, such as ecological protection, characteristic landscape, leisure and recreation. The ecological, cultural and economic values of resources are taken as the basis of identifying a greenway network. We establish the gravitation-resistance model to measure network flow based on the attraction and resistance between resources. In particular, by means of network flow analysis and the geographic information system (GIS), the resistance and gravity are assigned to the resources and landscapes, respectively. The attraction between elements is then measured using the gravitation-resistance model. The distribution of resources and the trend of integration are analyzed by the combination of the centrality of resources and the ratio of supply to demand. Based on the analysis results of network flow, the paper puts forward a strategy for developing a county greenway network, and improves the scientific evaluation of the spatial resource. It provides a new perspective for the construction of a county greenway network.
