【摘要】：对区域交通格局与区域经济格局之间内在逻辑关系的研究源远流长，廓清两者相互关系对区域城镇格局的规划和产业结构的调整具有现实意义。鄱阳湖生态经济区具有特殊的自然环境和社会经济等区位条件，有必要对该区域的交通和经济格局相互关系的特质进行洞悉。GIS空间分析方法在空间分布规律和空间关系等方面的研究上，具有传统分析方法不可比拟的优越性。本文通过对鄱阳湖生态经济区公路交通格局和经济格局的研究，进而对两者相互关系的探讨，尝试为构建区域交通和经济协调发展优化模式提供针对性和建设性的建议。本文基于GIS空间分析技术和公路网数据，对以南昌市为中心的鄱阳湖生态经济区小时交流圈进行划分；并讨论了2020年规划的交通网一日交流圈的范围；也利用重力度量模型、最短距离度量模型和路网变形系数模型构建评价指标体系，分析了鄱阳湖生态经济区31个县区、298个空间节点的公路路网通达性；最后，结合路网密度和GDP之间相关性的分析，对研究区域的交通发展与经济发展的相互关系进行了初步探究。通过对小时交流圈、路网通达性、经济联系度、城市断裂点和路网密度等角度的分析研究，，综合讨论了鄱阳湖生态经济区公路交通格局和经济格局两者相互关系的特质。研究结果表明：以南昌为中心的一日交流圈已经基本涵盖了鄱阳湖生态经济区东部和南部的各县市，2020年交通规划网完成后将实现一日交流圈涵盖整个地区。鄱阳湖生态经济区的公路路网目前发育并不成熟，其通达性的空间格局呈现出不规则的圈层结构，东西向的通达性递减趋势快于南北向，鄱阳湖西岸通达性优于东岸,受自然环境因素的影响显著。通过区域公路交通格局与经济格局的空间分布规律存在一定的相似性，并对鄱阳湖生态经济区未来交通建设提出建议。
[Abstract]:The study on the internal logical relationship between regional traffic pattern and regional economic pattern has a long history. It is of practical significance to clarify the relationship between them for the planning of regional urban pattern and the adjustment of industrial structure. Poyang Lake Ecological Economic Zone has special geographical conditions such as natural environment and social economy. It is necessary to understand the characteristics of the interrelation between traffic and economic pattern in this area. The spatial analysis method of GIS has incomparable advantages over the traditional analysis method in the study of spatial distribution law and spatial relationship. Based on the study of road traffic pattern and economic pattern in Poyang Lake Ecological Economic Zone and the relationship between them, this paper tries to provide some suggestions for constructing the optimal mode of regional traffic and economic coordinated development. Based on GIS spatial analysis technology and highway network data, this paper divides the hour exchange circle of Poyang Lake ecological economic zone centered on Nanchang city, and discusses the scope of the daily communication circle of traffic network planning in 2020. Using gravity metric model, shortest distance measurement model and deformation coefficient model of road network, the evaluation index system is constructed, and the road network accessibility of 298 spatial nodes in 31 counties and regions of Poyang Lake Ecological Economic Zone is analyzed. Finally, based on the analysis of the correlation between road network density and GDP, the relationship between traffic development and economic development in the study area is preliminarily explored. Based on the analysis and study of hour exchange circle, road network accessibility, economic connection degree, urban fracture point and road network density, the characteristics of the relationship between road traffic pattern and economic pattern in Poyang Lake Ecological Economic Zone are discussed synthetically. The results show that the one-day exchange circle centered on Nanchang has basically covered the counties and cities in the eastern and southern parts of Poyang Lake Ecological Economic Zone. After the completion of the traffic planning network in 2020, the one-day exchange circle will cover the whole area. The road network of Poyang Lake ecological economic zone is not mature at present, and its spatial pattern of accessibility shows irregular circle structure. The trend of east-west access decline is faster than that of north and south, and the accessibility of West Bank of Poyang Lake is better than that of East Coast. By the natural environment factor influence is remarkable. There are some similarities between the regional highway traffic pattern and the economic pattern, and some suggestions on the future traffic construction of Poyang Lake Ecological Economic Zone are put forward.
