With the continuous development and application of high-level science and technology, men go further and further in breadth and depth space of resources development and utilization. We would like to review the history of development of utilizing “horizontal” breadth & “vertical” depth spaces resources, and to look forward to its future, in order to observe the relation of “horizontal” between “vertical” and the relation between time and space during man’s utilization of resources in a four-dimensional view. “Horizontal” and “Vertical” are “three-dimensional” reference coordinates, while history and future are the “four-dimensional” time.
