STUDY OF THE PHENOLOGICAL PHASE OF VEGETATION USING SATELLITE REMOTE SENSING METHODS IN THE AREA OF MAGYARKANIZSA MUNICIPALITY

Summary/Abstract: According to a German scientific article published in February 1999 (Menzel & Fabian, 1999), the phenological phases of vegetation (the different periods of vegetation development) are more sensitive and easier to observe from year to year, and can therefore be an indicator of changes in the biosphere. The research examined data from more than 30 years1 in Europe and found that spring events, such as bud break, are occurring 6 days earlier, while autumn events, such as leaf colour change, are occurring 4.8 days later. This means that the average annual growing season has increased by 10.8 days since the early 1960s. These shifts can be attributed to changes in air temperature. Temperatures have risen over large parts of the northern hemisphere continents over the past century. In particular, minimum temperatures have shown a more pronounced increase than maximum temperatures. (Scheifinger, Menzel, Koch, & Ch, 2003) A study confirms that earlier flowering of plants can be observed in most places in Europe among the studied areas. (Schleip, H. Sparks, Estrella, & Menzel, 2009) During the preparation of this thesis, a report was prepared of the annual average temperatures and annual precipitation between 1984 and 2019, by examining the data of the hydrometeorological station closest to the studied area (Palic, Serbia).
