【摘要】：昌九一体化是江西省委省政府在2013年提出的经济发展战略,是为了策应长江中下游城市群的发展及推进鄱阳湖生态经济区的建设,目的是希望让南昌市和九江市这两个省内经济发展领军城市进行产业协调部署、资源共享、联动发展,组成区域经济协作的示范发展模式,带领全省经济全面发展。鉴于交通服务能力在区域发展中的基础地位和重要作用,对区域经济一体化的研究往往将交通服务能力和建设水平放在重点位置,而可达性是评价交通服务水平的有力指标。本文选择在促进昌九一体化视角下对昌九区域公路交通可达性进行研究,有以下考虑:(1)国内对于欠发达地区的一体化发展区域研究较少;(2)昌九一体化江西省重要的战略部署,其发展能够带动全省经济发展、产业布局优化;(3)将微观层面的研究方法和理论应用在小微区域,对拓展可达性运用尺度有现实意义。本研究从促进昌九一体化目的出发,以时间距离成本为评价指标,从不同层面、用多种尺度结合的方式定量分析昌九区域公路交通可达性,旨在评估现有公路交通基础设施水平和服务能力是否能满足昌九一体化发展的战略要求。研究表明:1)以南昌市城区和九江市城区为核心的小时交流圈均已覆盖昌九区域大部分地区,同城化效应已初步显现;2)受空间距离和交通状态双重影响,城区道路交通体系影响城区之间交流便捷性,需进一步提升城区主次干道的通行能力和通达水平;3)昌九区域整体可达性状况良好,但区域内差异大,可达性分布格局呈现高等级道路指向性、路网密度指向性。需进一步优化区域路网规划,提升路网布局平衡性;4)水系对昌九区域公路交通可达性的阻隔作用明显,水系两岸可达性值差异大,需结合隧道、桥梁建设减少水系对可达性的影响。在上述分析的基础上,本研究针对现有的交通建设、规划问题从增强昌九一体化程度的角度上提出了在交通建设和规划方面科学合理的意见和建议。
[Abstract]:Changjiu integration is an economic development strategy put forward by the Jiangxi Provincial Party Committee and the provincial government in 2013, in order to respond to the development of the urban agglomeration in the middle and lower reaches of the Yangtze River and to promote the construction of the Poyang Lake Ecological Economic Zone. The purpose of this paper is to make the leading cities of economic development in Nanchang and Jiujiang carry out coordinated industrial arrangements, share resources and develop in a coordinated way, and form a demonstration development model of regional economic cooperation to lead the overall economic development of the whole province. In view of the basic position and important role of traffic service capacity in regional development, the research on regional economic integration often puts traffic service capacity and construction level at the key position, and accessibility is the powerful index to evaluate the traffic service level. This paper chooses to study the accessibility of highway traffic in Changjiu region from the perspective of promoting the integration of Changjiu. There are the following considerations: (1) there are few studies on the integrated development of the less developed areas in China; (2) the important strategic deployment of Changjiu integrated Jiangxi Province, whose development can promote the economic development of the whole province and optimize the industrial layout; (3) the application of microcosmic research methods and theories in small microregions is of practical significance in expanding the application scale of reachability. Based on the purpose of promoting the integration of Changjiu and Changjiu, the paper takes the cost of time distance as the evaluation index, and quantifies the accessibility of highway traffic in Changjiu region by the way of combining various scales from different levels. The purpose of this paper is to evaluate whether the existing highway transportation infrastructure and service capacity can meet the strategic requirements of Changjiu integration. The results show that: 1) the hourly AC circle with Nanchang city and Jiujiang city as the core has covered most areas of Changjiu region, and the effect of co-urbanization has been preliminarily shown; 2) under the influence of space distance and traffic condition, urban road traffic system affects the convenience of communication between urban areas, so it is necessary to further improve the traffic capacity and accessibility level of the main and secondary trunk roads in urban areas; 3) the overall accessibility of Changjiu region is good, but there are great differences within the region. The distribution pattern of reachability shows high grade road directivity and road network density directivity. It is necessary to further optimize the regional road network planning and improve the balance of road network layout. 4) the water system has an obvious barrier effect on the accessibility of highway traffic in Changjiu region, and there is a great difference in the reachability between the two sides of the river system, so it is necessary to combine the tunnel and bridge construction to reduce the influence of the water system on the accessibility. On the basis of the above analysis, in view of the existing traffic construction, the paper puts forward some scientific and reasonable opinions and suggestions on traffic construction and planning from the angle of enhancing the integration of Changjiu and Changjiu.
