Abstract: | The paper is an expanded version of a Lomonosov lecture given April 12, 1956, in the Earth Science Museum of Moscow University. Yefremov criticizes the confusion derived from the dual meaning of “landscape” as used by Soviet geographers: (1) landscape as an areal unit of varying taxonomic rank constituting a complex of all components that interact within the earth's surficial sphere (or landscape sphere), and (2) landscape as an indivisible basic areal unit, or “molecule,” or “cell” of physical geography. Yefremov defends the first and assails the second point of view. |
