Abstract: 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.

Key words: channel, domain surface, network, node, resources flow, spatial perspective
