【摘要】：公路网空间分布格局与区域经济、人类生活布局不一致,严重制约着区域社会经济协调可持续发展。为了使公路网建设更好地服务于经济发展与人民生活,对公路网空间分布格局进行研究尤为必要。参考经济贫富差距的测定方法,构建表征公路里程相对区域面积、人口数量、各产业产值及经济总产值分布格局的洛仑兹曲线,定量计算衡量青海省国、省道布局与以上诸要素协调程度的基尼系数,反映国、省道建设的公平性与合理性,为未来公路网规划建设的协调有序发展提供基础信息。综合计算结果表明,青海省国、省道里程相对地域面积的分布较为均衡合理,但与人口数量、经济产值的相对布局严重失衡,建议合理规划公路网建设,有效调整产业布局。
[Abstract]:The spatial distribution pattern of highway network is inconsistent with regional economy and human life distribution, which seriously restricts the coordinated and sustainable development of regional social economy. In order to make the construction of highway network better serve the economic development and people's life, it is necessary to study the spatial distribution pattern of highway network. Referring to the measurement method of the economic gap between the rich and the poor, the Lorentz curve, which represents the relative area of highway mileage, the number of population, the output value of each industry and the distribution pattern of economic output value, is constructed, and the country of Qinghai Province is quantitatively calculated and measured. The Gini coefficient of the coordination degree between the distribution of provincial roads and the above elements reflects the fairness and rationality of the construction of provincial roads in the country and provides basic information for the coordinated and orderly development of the future highway network planning and construction. The comprehensive calculation results show that the distribution of relative area of provincial mileage in Qinghai Province is more balanced and reasonable, but it is seriously unbalanced with the relative distribution of population and economic output value. It is suggested that the construction of highway network should be rationally planned and the industrial layout adjusted effectively.
