基于GIS的湖北省交通运输基础设施空间特征研究

Spatial Characteristics of Transportation Infrastructure in Hubei Province Based on GIS

以湖北省市域为研究单元,借助GIS对数据的采集、分析功能,获取各市道路网密度、站场密度.在道路网基础上深化对站场的研究,以此探讨综合交通运输基础设施与地形、人口密度、GDP密度等多维因素的相关性,评估湖北省交通发展水平,并为预测未来湖北省各市路网发展变化提供依据.结果表明:湖北省道路、站场(加权)密度具有集聚特征,并由鄂东地区至鄂西地区依次减小;交通设施密度随地势增高而降低,并且与人口密度、GDP密度呈正相关性,但有少数城市交通发展水平较湖北省整体水平偏低.

Taking the city area of Hubei Province as the research unit, the density of road network and station yard of each city can be obtained by using data collection and analysis of GIS. On the basis of road network, the study of station yard is deepened in this paper. The correlation between comprehensive transportation infrastructure and multi-dimensional factors such as topography, population density, GDP density is explored to evaluate the level of transportation development in Hubei Province. The correlation can be used as the basic data for predicting the future development and changes of road network in various cities of Hubei Province. The results show that the density of roads and stations (weighted) in Hubei Province has the characteristics of agglomeration, and decreases in turn from Eastern Hubei to Western Hubei. The density of transportation facilities decreases with the increase of terrain, and is positively correlated with population density and GDP density. However, a few urban traffic development levels are lower than the overall level of Hubei Province.
