EXPERIENCE OF EVALUATING THE COMPOSITION AND PROPERTIES - OF THE LITHOGENIC BASE OF THE WORLDS ECOSYSTEMS

Properties and reactions of the main petrographic and mineralogical or ders of land ecosystems are investigated. The intensities and diversit y of fourteen globally significant orders, that is, their potential ec ological variability, are estimated, and the categories of variability are calculated. The highest categories characterize the orders of the lithogenic base of ecosystems of the main agricultural territories. T he ecological variability of petrographic and mineralogical orders of ecosystems is formed in the prolonged evolution of the geographical en vironment.
