Statistical Characteristics and Community Analysis of Urban Road Networks

“…As can be seen, TABLE Ⅲ shows how these networks rank in terms of their robustness. The WBC can measure how frequently a given node of URNs can be passed by the shortest paths of all OD pairs [3]. According to [27], a network is more robust if the proportion of nodes with high BC is lower, which means the WBC of a network can be related to the robustness of the network.…”

“…Urban road networks (URN) are crucial infrastructure components of urban transportation and constitute an essential backbone underpinning most social and economic activities [2,3]. Road traffic networks and infrastructure are vulnerable to disasters [4][5][6], however, some of which, like extreme weather events or earthquakes, can be so disruptive as to lead to a complete system failure [7,8].…”

To date immunity to disruptions of multi-scale urban road networks (URNs) has not been effectively quantified. This study uses robustness as a meaningful -if partialrepresentation of immunity. We propose a novel Relative Area Index (RAI) based on traffic assignment theory to quantitatively measure the robustness of URNs under global capacity degradation due to three different types of disruptions, which takes into account many realistic characteristics. We also compare the RAI with weighted betweenness centrality, a traditional topological metric of robustness. We employ six realistic URNs as case studies for this comparison. Our analysis shows that RAI is a more effective measure of the robustness of URNs when multiscale URNs suffer from global disruptions. This improved effectiveness is achieved because of RAI's ability to capture the effects of realistic network characteristics such as network topology, flow patterns, link capacity, and travel demand. Also, the results highlight the importance of central management when URNs suffer from disruptions. Our novel method may provide a benchmark tool for comparing robustness of multi-scale URNs, which facilitates the understanding and improvement of network robustness for the planning and management of URNs.

“…ese results could be attributed to the increases in woodland, which offset the value of individual services lost by reducing cultivated land. A comparison of the traditional and landscape ecology planning schemes reveals that the latter can improve the area's comprehensive service function value, prevent the simple pursuit of grain production, and realize the modern land regulation goals of protecting biodiversity and improving rural ecological service functions and landscape value through natural resource protection [44], the biological restoration of the ecological environment, nonpoint source pollution control, and the construction of ecological networks and green infrastructure [45].…”

Improving Land Use Planning through the Evaluation of Ecosystem Services: One Case Study of Quyang County

Competition for land is increasing as demand for multiple land uses and ecosystem services rises. Land regulation of the principles of landscape ecology is necessary to develop more sustainable approaches to land use planning. The research evaluated the present land patterns and determined best practices for its regulation of Dongwang Township in Quyang County, located in the Taihang Mountain area of Hebei Province, China. The research used the landscape ecology theory to construct an index system for landscape pattern analysis based on the GIS and Fragstats 3.3 software. In this study, we examined the specific reasons that landscape ecology is superior to traditional methods in land consolidation planning and design, which is conducive to the comprehensive development of land ecological benefits. Landscape ecological planning can effectively reduce landscape fragmentation and improve intensive management. The result found that the descending order of the Shannon index was current landscape, landscape ecological planning, and traditional planning. Landscape ecological planning could protect the natural diversity than traditional planning. Landscape ecological planning enables the creation of long corridors, with higher densities and connectivity and lower average corridor widths than traditional planning. Besides, it can improve ecological service function values in the study area to varying degrees, thus discouraging residents from limiting themselves to grain production. This research has great potential to improve the visibility of ecosystem services in local land use planning and, thus, to improve the ecological functioning of future landscapes.
