METHOD FOR REMOTE DETERMINATION OF ANTHROPOGENIC TRANSFORMATION OF PHYTOCENOSIS IN THE STRIP OF REMOVAL OF TRANSPORT ROUTES AND POWER TRANSMISSION LINES Russian patent published in 2019 - IPC G01N33/00 G01C11/00 

FIELD: physics.

SUBSTANCE: invention relates to the field of earth surface exploration. Method is implemented using an IPVI vegetation index in a strip of off-take of transport routes and power transmission lines. At that, using aircrafts, remote digital geocoded spectrozonal photography is carried out and ground-based digital spectral photography is carried out using a spectroradiometer in range of 320 to 1,100 nm with division into subranges of the transport and power transmission lines of the earth's surface referred to the strip of discharge, as well as located in this band of reference sections of dominant phytocenosis in summer. Obtained spectrozonal images are converted into colour synthesized by vegetation index, computer estimation of energy distribution of said image is carried out and compared with data of spectral ground survey of reference section with established phytocenosis on levels of reflected energy, outlines of dominant phytocenosis are separated with separation according to levels of vegetation index IPVI, as well as surface contours in the absence of phytocenosis, creating cartographic geo-information layers of phytocenosis contours by levels of the vegetation index IPVI and surface contours in the absence of phytocenosis, transforming such layers into a map projection corresponding to the working scale of the map, spatial arrangement and area of each circuit are set, and the level of anthropogenic transformation in the strip of removal of transport routes and power transmission lines is determined from the ratio of the sum of areas of contours with IPVI values from 0 to 0.6 to the total area of the withdrawal strip. At that, assessment of degree of anthropogenic transformation of phytocenosis is carried out according to scale of values of anthropogenic transformation level, and at 0.8–1 phytocenosis are completely transformed with rarefied ruderal phytocenosis, at 0.6–0.8 is strongly transformed with dominant ruderal phytocenosis, at 0.4–0.2 weakly transformed with domination of natural phytocenosis, level of anthropogenic transformation <0.2 characterizes completely restored natural phytocenosis.

EFFECT: higher information value and reliability of determination.
