Abstract: What is geography? In the author's opinion, the geographical ideas, as a historical product, advance and evolve with the progress of epoch. Therefore, geographers should keep a dynamic view in recognizing the discipline they devoted to. As different countries have various historical, physical, social and economic conditions, their geographies are developed according to different models and tackle different problems. So, the development of geography also has areal differentiation among countries. Actually there is no one geography the world over. The author tries to verify his views by analysing the changes of the ancient, the modern and the contemporary geographies and the variances between the W. European, the N. American and the Soviet geographies. The ideas of "quantitative revolution", "theoretical revolution", regional science, Marxist geography, unified geography and the rejuvenation of regional geography are introduced in the paper.

Key words: development of geography, quantitative revolution, theoretical revolution, regional science, Marxist geography, unified geography, rejuvenation of regional geography
