基于空间视角的资源流动内涵与构成要素的再思考

资源流动研究已成为资源科学领域新的研究视角和学科成长点,但对资源流动的理论提升、方法总结和范式探讨依然相对较少。论文从地理学的空间视角,对资源流动的内涵及构成要素进行分析。论文给出资源流动的定义,并指出,节点具有业务职能功能、效用功能及社会经济功能,空间位置和流量是节点两个突出的空间特征,不同的节点必然会形成不同的等级,未来应加强对节点功能的量化分析以及完善和发展节点分布特征及等级划分的研究方法;通道和网络具备从属和引导功能,衡量其发育程度主要根据网络的结构特征与网络节点特征,未来应探讨伴随新的交通方式而出现的新功能,系统地对通道网络进行优化分析,构建集多种运输方式为一体的多方式的资源流动通道网络优化模型,针对资源流动流量、强度以及成本等因素进行优化研究;域面是节点、通道网络的载体,根据资源流动节点吸引和辐射的范围,可以将域面划分为不同的等级,加强国际市场因素对我国资源流动域面影响的研究。同时指出,进一步从理论上探讨节点、通道、流动网络及流场的类型,在流动中所起的作用以及彼此之间的作用机制等,将是对资源流动构成要素研究的重要突破。

Rethinking of Connotation and Constituent Elements of Resources Flow Based on Spatial Perspective

Research of resources flow has become a new perspective, but it is still lack of the theories, approaches summary and paradigms of the research. The theory, method and innovation of the research framework need to be expanded and improved. In order to reveal the connotation and the constituent elements of resources flow based on spatial perspective, this article summarizes the theoretical studies on resources flow from the aspects of connotations, essence, and elements. Resource transverse flow relies on the geographical space, and different geographical space has different natural phenomena and cultural phenomena, so it is of great significance to study the resources flow from the perspective of space. The resource flow is defined from the perspective of space in this article. The potential differences of resources exist among regions, so one-way flow, bidirectional flow and multidirectional flow will happen because of the force of the resource field and the external force. A node has business function, utility function and social economic function. Spatial location and traffic are two prominent spatial characteristics of the nodes. Different nodes are at different levels. In the future, the quantitative analysis of the functions should be strengthened, so are the methods to divide the hierarchy. Channels and network have the functions of affiliation and guiding. Their development degrees are mainly measured from the structure and the nodes of the network. In the future, new functions will appear with the emergence of new way of transportation, so the new functions should be discussed and the channel network system should be optimized. Building an optimization model including a variety of modes of transportation which can study resources flow, intensity and cost has important practical significance. Domain is the carrier of nodes, channels and networks. The influence of international market on the resources flow domain should also be studied. Research also points out that it is important breakthroughs of the study of the constituent elements of resources flow that further theoretically explores node, channel, network types of resources flow and the roles and the mechanisms among them. Space factors of resources flow are important content of the theory research. It is of great significance to understand the spatial pattern and the structure of the resources flow. The exploration of new analysis model on the basis of empirical research combining with the new element that will emerge in the future will be the important breakthrough in the study of resource flow elements. The establishment of the theoretical system of resource flow must be based on a multidisciplinary integration. Research of resources flow is involved in resources science, eco-logy, economics, management, sociology and geography and so on, but these disciplines have not been jointly researched. It is the key to combine the study in resources science, ecology, economics, management, sociology and geography and integrate their theories.
