A method for isolating the transition zones (ecotones) of different spatial levels in subboreal LANDSCAPES

摘要

A method of isolating the transition zones (ecotons) different spatial levels in Subboreal landscapes comprising identifying communication geographical zones with radiation heat flux on land and radiation dryness index, allocation inside each latitudinal zone boundaries natural areas corresponding to specific values ​​of radiation dryness index, characterized in that Feedback radiative heat flux on land - (R) with the normalized latitude subbborealnogo belt - (x) describe the energy balance equation geog aficheskih zones logistic function expressed by R = A / [1 + 0,72exp (4,25-Bx)] + C, where A - radiative heat flux coefficient B - zoning coefficient C - minimum annual radiative heat flux, and for zero (0) normalized latitude range adopted Latitude 90 °, and the unit (1) Latitude 0 ° (equator), the allocation ecotons produce: the zero value of the second derivative determined latitude center ecotone first spatial level and on its extrema - latitude and lower ecotone upper border of the first spatial level of zero values ​​of the third and subsequent derivatives establish centers interzonal Ecotones appropriate spatial level, and by determining the extrema of these derivatives transition zones latitude boundaries (ecotons) and secrete them latitudinal range.
