以我国石油(特指原油)资源流动为研究对象,以我国省级行政单元作为石油资源空间流动的节点,从1985~2007年中选取5个特征时点,借助齐夫定律,研究了我国石油资源输出量和输入量的位序-规模分布特征。结果表明:(1)各特征时点石油输出量和... 以我国石油(特指原油)资源流动为研究对象,以我国省级行政单元作为石油资源空间流动的节点,从1985~2007年中选取5个特征时点,借助齐夫定律,研究了我国石油资源输出量和输入量的位序-规模分布特征。结果表明:(1)各特征时点石油输出量和输入量的位序-规模分布均满足齐夫法则。(2)从无标度区范围来看,石油输出量的无标度区范围变化不大,而输入量的无标度区范围呈现出先缩小后又逐年扩大的趋势。(3)从空间分形结构来看,石油输出量的无标度区没有分段,始终呈现为单分形,而输入量则经历了由双分形向单分形的演化。(4)从空间分布形态来看,各特征时点石油输出量均呈帕累托分布模式,而输入量的空间分布形态变动较大,经历了对数正态模式—帕累托模式—对数正态模式—帕累托模式的演变。我国石油输出量和输入量位序-规模分布的不同步变化,与大油田分布、石化产业布局以及石油流通体制等有着密切联系。 展开更多

In a world of climate change and socio-economic development, oil is the strategic resource that is closely intertwined and interdependent. Tracing the evolution of petroleum resources flow is fundamental to understanding petroleum supply and demand, and can also serve as the basis for assessing CO2 emissions from petroleum products. This paper aims to provide a petroleum products flow accounting framework that divides petroleum flow into four phases, three flows, three libraries, and two processes, and summarizes the approach to measure and analyze petroleum resources flows. It takes China as an example for empirical research, and finds that: ①China's petroleum production, consumption and import have significantly increased over the past two decades, and the combination of increasing demand and limited supply have created an urgent need for China to diversify its petro-leum sources globally to ensure its oil security.②Final consumption accounts for the use of most petroleum products and special attention should be paid to the losses in the petroleum refining process. ③With the exception of crude oil, petroleum product flows among various sectors has changed greatly. Particularly, the flow of petroleum products into transport and residential consumption has trended upward significantly, whereas the flow to industry is trending downward.④CO2 emission data shows that CO2 emission amounts increased rapidly from 456Mt in 1993 to 1517Mt in 2013. Previously, the top three C02 emitters were the industrial sector, the transport sector including the transport, storage and post segments, and the thermal power sector. Currently, the largest emitters are the transport sector, the industrial sector and the residential consumption sector. Finally, poorly demarcated system boundaries and incomplete databases and models constrain research on industry flows of petroleum resources for non-energy use. 展开更多
