The Tentative Research On The Relationship Between The Traffic Patterns In Poyang Lake Eco-Economic Region Based On Spatial Analysis

The study on the internal logical relationship between the regional transportationand economic patterns has a long history; to clear the interactive mechanism betweenthe two above is very important to the programming of the urban pattern and theregulation of the industrial structure. The Poyang Lake eco-economic region isdifferent in its nature environment and social economical environment, thus, it’s verynecessary to know the relationship clearly. The GIS spatial analysis methods aresuperior to the traditional ways in the spatial distribution and spatial relationship. Byanalyzing the regional traffic and economical patterns and making further study on therelationship, this essay is trying to provide usable advices for the development of thetraffic and the economy.This essay is based on the GIS spatial analysis technology to divide the PoyangLake eco-economic region which set Nanchang as the center; discussed the range ofthe daily communication area after the building of the network in2020. Then, webuild index system by using the gravity measure model, network deformationcoefficient model and the shortest measure model and make analysis of the roadaccessibility of31counties and298space nodes within the Poyang Lakeeco-economic region. Finally, we study the relationship between the regional trafficand the development of the economy combined with the study of the network densityand the GDP.Through the analysis of the different angles such as hourly communication area,network accessibility, economic connection, city breaking point and network densityetc. we achieve some results about the relationship between the traffic and theeconomic pattern. The results showed: The daily communication area which setNanchang as the center is covered the whole counties of the east and south of thePoyang Lake eco-economic region and it will cover the whole area after thecomplement of the traffic planning nets in2020. The network of the Poyang Lakeeco-economic region is not ripe and is susceptible to the nature environment, so theaccessibility of the network showed an irregular layer structure. The decline trend ofthe accessibility in the east-west is faster than the north-south. The accessibility of the west bank of the Poyang Lake is better than the east bank. And finally, we provideconstructive advices for the construct of the Poyang Lake eco-economic region.
