摘　　要：以陕西省为研究区,使用GIS空间分析方法,定量分析公路网建设、人口、GDP、海拔的空间分布特征。提出评价公路网建设与经济发展适应性的空间分析方法,以辅助公路工程预可研决策。研究方法也可为其他区域公路工程规划决策提供参考。In the pre feasibility evaluation stage of new highway projects,the traditional methods can not accurately analyze the micro correlation between the scale of regional highway network and regional economic development,topography and landform.Taking Shaanxi Province as the research area,we used GIS spatial analysis method to quantitatively analyze the spatial distribution characteristics of highway network construction,population,GDP and altitude.Then,we put forward a spatial analysis method to evaluate the adaptability of highway network construction and economic development to assist highway engineering pre feasibility study decision.The results show that(1)the spatial dependence analysis method can evaluate the rationality of the overall scale of the highway network,and provide technical support for the decision-making of road network construction planning.(2)The global spatial autocorrelation analysis of highway network density shows obvious spatial heterogeneity,and the overall scale of highway network construction in Shaanxi Province can meet the demand of regional population and economic scale in Shaanxi Province.However,the construction structure of highway network is not reasonable.The imbalance of highway network layout restricts the coordinated development of regional economy in Shaanxi Province.The research method can provide reference for other regional highway engineering planning decisions.
