Assessment of Natural Plant Communities through the Use of Remote Sensing Data of the Stavropol Territory Steppes

Introduction. The relevance of the study steppe phytocenoses is caused by unsatisfactory state natural grass stands, namely a low level biodiversity and high degree degradation. aim work to determine features connection Earth remote sensing data with degradation stands in unstable moistening zone arid Stavropol Territory. certain temporal spatial resolutions make it possible carry out almost continuous monitoring stands. Materials Methods. was carried 2016–2020 on ground at discount areas (100 m2) according requirements methods generally accepted phytocenology. Vegetation condition assessed using based values Normalized Difference Index. According satellite data, Index cartograms were constructed for each point study. Results. proportion polygons 18.8% research objects located an average 37.5%, while 70.6 23.5%, respectively. In moistening, highest coefficients rank correlation between area occupied herbaceous vegetation value index are observed case if range 0.0–0.4, 0.0–0.3 (at 0.01 significance level). Discussion Conclusion. When assess ecosystems Territory, necessary use regression models specific various soil climatic conditions.
