The effect of the hydrothermal conditions of the Tom River Basin on the ecological structure of flora

Abstract

This paper presents the results of studying the relationship of the hydrothermal conditions (air temperature and precipitation) and the ecological spectrum of the flora of vascular plants in the Tom River Basin. Based on the calculated coefficients of linear correlation of the average monthly data on temperature and precipitation with the ecological groups of model basins, it is found that the influence of the main parameters of the hydrothermal regime (temperature and precipitation) in the plains and in the mountains affects the ecological spectrum of the flora to varying degrees. The greatest impact on the properties of the ecological spectrum is made by the hydrothermal conditions of the cold part of the annual cycle.
