BASIC TENDENCIES IN CHANGES OF THE EARTHS VEGETATION IN RELATION TO GLOBAL WARMING OF THE CLIMATE

An analysis is presented of current approaches to prediction of possib le changes of vegetation in relation to existing tendencies in global warning of the climate. Preference is accorded to the structural-funct ional approach in plant ecology based on study of the dissemination of plants with different types of photosynthesis (C3, C4, and CAM) and v ariants (biochemical and structural) of the C4 syndrome in relation to climatic factors. The possibility of realization of such an approach is demonstrated on the example of the latitude, altitude, and edaphic distribution of species of the families Poaceae and Chenopodiaceae.
