The Role of Geographers in the Study,Mapping, Economic Appraisal,Utilization, Conservation and Renewal of the Natural Resources of the USSR

The paper discusses, mainly from a programmatic point of view, the need for research into the relationships between climate and vegetation. Four lines of research are proposed: (1) the correlation between the distribution of vegetation and climate indices; (2) relationships between the distribution of vegetation and seasonal types of climate; (3) seasonal and annual changes in plant communities related to corresponding changes in the surface layer of the atmosphere and the soil and subsoil; (4) the exchange of matter and energy within an ecological system.
