【摘要】：對區(qū)域交通格局與區(qū)域經濟格局之間內在邏輯關系的研究源遠流長，廓清兩者相互關系對區(qū)域城鎮(zhèn)格局的規(guī)劃和產業(yè)結構的調整具有現(xiàn)實意義。鄱陽湖生態(tài)經濟區(qū)具有特殊的自然環(huán)境和社會經濟等區(qū)位條件，有必要對該區(qū)域的交通和經濟格局相互關系的特質進行洞悉。GIS空間分析方法在空間分布規(guī)律和空間關系等方面的研究上，具有傳統(tǒng)分析方法不可比擬的優(yōu)越性。本文通過對鄱陽湖生態(tài)經濟區(qū)公路交通格局和經濟格局的研究，進而對兩者相互關系的探討，嘗試為構建區(qū)域交通和經濟協(xié)調發(fā)展優(yōu)化模式提供針對性和建設性的建議。 本文基于GIS空間分析技術和公路網數(shù)據(jù)，對以南昌市為中心的鄱陽湖生態(tài)經濟區(qū)小時交流圈進行劃分；并討論了2020年規(guī)劃的交通網一日交流圈的范圍；也利用重力度量模型、最短距離度量模型和路網變形系數(shù)模型構建評價指標體系，分析了鄱陽湖生態(tài)經濟區(qū)31個縣區(qū)、298個空間節(jié)點的公路路網通達性；最后，結合路網密度和GDP之間相關性的分析，對研究區(qū)域的交通發(fā)展與經濟發(fā)展的相互關系進行了初步探究。 通過對小時交流圈、路網通達性、經濟聯(lián)系度、城市斷裂點和路網密度等角度的分析研究，，綜合討論了鄱陽湖生態(tài)經濟區(qū)公路交通格局和經濟格局兩者相互關系的特質。研究結果表明：以南昌為中心的一日交流圈已經基本涵蓋了鄱陽湖生態(tài)經濟區(qū)東部和南部的各縣市，2020年交通規(guī)劃網完成后將實現(xiàn)一日交流圈涵蓋整個地區(qū)。鄱陽湖生態(tài)經濟區(qū)的公路路網目前發(fā)育并不成熟，其通達性的空間格局呈現(xiàn)出不規(guī)則的圈層結構，東西向的通達性遞減趨勢快于南北向，鄱陽湖西岸通達性優(yōu)于東岸,受自然環(huán)境因素的影響顯著。通過區(qū)域公路交通格局與經濟格局的空間分布規(guī)律存在一定的相似性，并對鄱陽湖生態(tài)經濟區(qū)未來交通建設提出建議。
[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.
