摘要：

The article describes main trends of modern changes in the most important parameters of the ecological and climate system of the Republic of Mordovia. Based on the spatio-temporal analysis of the relationship between climate component modifications, the authors formulate general provisions with regard to the changes that are occurring on regional agroecosystems in the studied region. The yield of agricultural crops correlates more with integral indicators such as bioclimatic potential, the modifications of which reflect the complex influence of changes in the regional climate system on the production capacities of agroecosystems rather than the extremes of individual climate parameters. The conducted research revealed a tendency to decreasing the bioclimatic potential on the territory of Mordovia against increasing in the sum of active temperatures and an increasing the duration of the vegetative period, which is associated with a decrease in the annual amount of precipitation and, in general, humidification of the territory, which are the main factors in the climate production conditions in Mordovia's current climatic conditions. Calculations of the biological efficiency index of the climate showed a significant spatial variability, which is expressed in a decrease the index from the north-west to the south-east of the republic. Nevertheless, for most farms in the administrative regions of the republic, you can state a high efficiency of using the ecological and bioclimatic potential of landscapes, which affects the volume of agricultural production.
