Research On The Temporal And Spatial Evolution And Formation Mechanism Of Oil Resource Flow Characteristics In The “Belt And Road” Countries

On a global scale,the spatial distribution of oil production and consumption is highly separated,which inevitably leads to the phenomenon of oil resource flows.The rich oil reserves of the "Belt and Road" have enormous potential for development in this region.The paper takes the horizontal flow of petroleum resources in the "Belt and Road" as the research object,analyzes the flow characteristics of petroleum resources and the spatial pattern of source-settlement system in 1995-2016,discusses the mechanism of this change,and formulates the oil trade strategy for China.Provide theoretical basis and further enrich the research and development of petroleum geography.Specifically:First of all,this paper is based on the statistical data of the "One Belt and One Road" oil-related countries(in this paper,especially crude oil),and the overall analysis of the changes in the input and output of the "One Belt,One Road" oil-related countries.The results show that the "One Belt,One Road" petroleum resources are generally oversupply,and the output status is still stable and outstanding;the "One Belt,One Road" oil output and input volume order-scale are in line with the Qifu rule,and the space of the two scale structures The changes are not synchronized,but they all tend to mature;the spatial distribution pattern of output scale has always been Pareto mode,and the difference in input size distribution is smaller than the difference in output size distribution,but it is developing in an unbalanced direction;the absolute difference in output is The fluctuations are widened,the relative differences are not obvious,and the overall stability is presented.The absolute and relative differences in input are expanding.On this basis,the paper analyzes the evolutionary characteristics of the spatial pattern of petroleum resources flow in the "One Belt,One Road" oil-related countries.The study found that the change in the number of source and sink places is not obvious,and the ratio of the total export volume of the source land to the total import volume of the land is decreasing year by year;the large-scale sources of Saudi Arabia and Russia maintain high output and have outstanding advantages in oil output The distribution of source and output is highly uneven;the increasing input of the two major sinks in China and India has led to a more and more significant differentiation of the input volume of the sinks,which tends to be unbalanced,and the polarization of the input of the sinks is becoming more and more significant;The center of gravity centered on the "Belt and Road" is located in the east,the spatial distribution shows the northeast-southwest pattern,and gradually slopes toward the southwest.The geometric center of the center of gravity of the sink is southeast,which is a one-way moving path,showing a northwest-southeast trend.Finally,through comparative analysis of the oil production,consumption,GDP and circulation conditions of the "Belt and Road" countries and the movement trajectory and spatial coupling of the source and sink system,the mechanism of the"One Belt,One Road" petroleum resource flow source and sink system is discussed.The analysis shows that the center of gravity of the production has the greatest influence on the spatial evolution of the center of gravity of the source,and the circulation condition is second;the consumption,circulation conditions and GDP center of gravity all shift the center of gravity of the land to the east,and the impact of GDP increases.
