摘要
道路网密度的研究有助于区域交通规划的制定,对区域经济发展具有促进作用。以贵州省88个县(区)为研究单元,以总道路网密度和加权道路网密度为主要指标,综合运用空间分析方法研究贵州省农村“组组通”背景下道路网密度的空间分布特征,并对道路网密度与社会经济因素的相关性进行初步分析。结果表明:(1)贵州省总道路网密度的平均值为0.702km/km2,加权道路网密度的平均值为0.060km/km2,省内各县(区)的道路密度差异较大,道路网空间分布不平衡;(2)贵州省各县(区)路网密度在空间上存在正相关性,空间分布具有一定的集聚特征;(3)贵州省道路网密度与人口密度、GDP密度表现为显著正相关关系。
The study of road network density contributes to the formulation of regional transportation planning and promotes regional economic development.Taking 88 counties of Guizhou Province as the research unit,using the total road network density and the weighted road network density as the main indicators,the spatial distribution characteristics of the road network density under the background of"Roads Connectivity among Villages"in Guizhou Province are studied by using spatial analysis method.The correlation between road network density and socio-economic factors is analyzed.The results show that:(1)the average value of total road network density in Guizhou Province is 0.702 km/km2,and the average value of weighted road network density is 0.060 km/km2.The road density of each county is quite different,and the spatial distribution of the road network is not balanced.(2)There is a positive correlation between the network density of counties in Guizhou Province,and the spatial distribution of road network density has certain agglomeration characteristics.(3)There is a significant positive correlation between the road network density,the population density and GDP density in Guizhou Province.
