PHOTOSYNTHETIC AND PRODUCTION POTENTIAL OF PLANTS IN ZONAL AND INTRAZONAL ECOSYSTEMS OF MONGOLIA
A comprehensive stationary study of zonal and intrazonal ecosystems (montane, dry and desert steppes, different types of deserts, floodplain meadows) was conducted in Mongolia for many years within the framework of the Joint Biological Expedition with USSR (now Russia). An important place in this complex was taken by the study of the dynamics of plant photosynthesis and primary biological production. Under fluctuations of the total and monthly precipitation, as well as with or without additional watering, the regularities of changes in maximum photosynthetic capacity and plant production are revealed. According to connection equations between these integral characteristics of plant growth and development, the values of production potential are calculated in some communities.
