THE ESTIMATION OF SPATIAL AND TEMPORAL REGULARITIES OF BIOLOGICAL PRODUCTIVITY OF PINE (PINUS SYLVESTRIS) IN MESCHERA SUBTAIGA ECOSYSTEMS(according to the materials of tree-ring research)

The results of the researches which have been devoted to the study of the factors of biological productivity of the pines growing in the forest phytocenoses of Ryazan Meschera have been generalized. The factors of biological productivity for the circulation periods of Vangengeim - Girs have been established by using of the dendrochronology. It is established that the factors of autumn and winter periods have the great significance for the growth of the pine in conditions of sandy soil and deep groundwaters. The factors of summer period have the great significance for the bioproductivity of the pine in conditions of wetland. It is shown that the pines growing in the different conditions of the habitat have similar changes of biological productivity.
