Determination of the state of artificial plantings of the green belt of Astana using remote sensing data of the Earth

To determine the further strategy of conservation and maintenance of artificial plantings of the green belt of Astana, it was necessary to assess the vital condition of woody and shrubby plants, which became the primary task of our research. For this purpose, ground-based taxational observations were carried out, multispectral data of remote sensing of the Earth (remote sensing) and GIS tools were used. The purpose of the research was to determine the areas of weakened and dying forest crops in the green belt of Astana using remote sensing data. The research methodology consisted in laying reference plots in forest crops of various species composition and age, in which trees were taxed and their vital condition was determined. Based on the decoding of multispectral images of reference sites, the identification of the rock composition and the living condition of artificial plantings of the entire green zone of Astana was carried out. As a result of ground-based research and remote sensing data processing, it was revealed that in the green belt of Astana, the main area is occupied by forest crops related to the «weakened» state of life – 40.3%. «Healthy» forest crops occupy 31.5% of the area, «dying» – 28.3%.
