Problems solved by technology

However, most of the existing achievements are based on the topological statistical parameters of complex networks, ignoring the geographic space attributes of the traffic network ontology, that is, only considering the connectivity of the network and ignoring the actual distance, resulting in the fact that the land use correlation analysis cannot be truly Reflecting the role of the road network, it cannot effectively reveal the spatial differentiation of land use landscape patterns

Embodiment

[0037] Such as figure 1 Shown, the detailed steps of the present invention are as follows:

[0038]1. Process road data and land use data (shp format) through ArcGIS10.1 software. Create a geographic database (GeoDatabase) and create a new dataset (dataset) in it, create a topology, and create a topology according to the prompts, add topology processing rules; perform topology analysis. The topological processing rules include must not have pseudo-nodes, must not have wired overlap (between different elements) (must not overlay), must not self-cover (must notself overlay), must not have wired intersections (between different elements) (must not intersect), and must not self intersect. After the topology processing is completed, build a network dataset (NetWork Dataset) for roads under the same dataset. Set the corresponding traffic speed according to the road level, and set the time and distance respectively when setting the impedance attribute. The time is the length divid...

Abstract

The invention relates to a method for quantifying characteristics of a road network and the effect of the characteristics of the road network on land utilization, and belongs to field of traffic and land utilization planning. The method for researching correlation between roads and land utilization includes the steps that center values of road segments in the road network are quantified through a complex network multi-centricity measurement model, a region is divided into sub regions of different grades according to the center degree through a nuclear density evaluation and reclassification method, landscape indexes of the sub regions are calculated, and eventually correlation coefficients between road centrality and land utilization landscape patterns are obtained respectively through Spearman rank correlation analysis. According to the method, the center characteristics of the road network are taken into account from the geographic space aspect, the structure of the road network is measured, and the characteristics of the road network and interaction between the characteristics of the road network and region land utilization are better quantified compared with traditional road characteristic parameters, and theoretical support is provided for traffic network and land utilization planning.

Description

technical field [0001] The invention belongs to the field of traffic and land use planning, in particular to a method for quantifying road network characteristics and land use effects. Background technique [0002] The transportation network system plays a key role in the economic development of the urban agglomeration and the formation of the spatial structure. While bringing extensive social and economic benefits, it also changes the surrounding environment. It is an important research direction of transportation geography to deeply reveal the comprehensive effect and mechanism of infrastructure network on the natural-human-society-environmental system, and to explore the mechanism and approach of adjusting and optimizing the relationship between infrastructure network and regional development. As a typical geospatial network composed of intersections of several linear entities and linking entities, the distribution and structure of the road network determine the location ...
