Estudio multitemporal de la cobertura vegetal de los ecosistemas de la zona norte de la provincia de Chimborazo a través de imágenes satelitales “LANDSAT 8”.

Abstract

The present investigation proposes: to realize a multitemporal study from the vegetal cover of the ecosystems in the north zone from Chimborazo province through LANDSAT 8 satellite images; It implied the use of satellite images generating special information from different periods in the years 2013, 2015 and 2018 with the purpose of analyzing the tendencies of change at the vegetation cover, percentages and the dynamics experienced by the ecosystems of the 5 cantons within the study where samples of the diagnostic species of these ecosystems were also collected, an unsupervised classification was made giving as a result 16 categories, thus taking into account that the exchange rate within the 2013-2018 it is evidenced that the category of intervention represents the category with the greatest extension, which experienced a growth of 1.605%, which means 4530 from the year 2013, occupying 54.89% in the year 2018 of total area, meanwhile the urban area category is the one that more growth experimented in different periods, in 2013 year this category occupied 2.91% of the total of the area, in the year 2018 it increases 2.06% that occupies the 4,97% of the total area, however the ecosystems of badlands with their different categories occupies 32,02%, the same one that has experienced a decrease in 2,59% since 2013, while the forests for the year 2018 have the same 7.11% which experienced a decrease of 1, 03% during the 5 years of study being anthropic activities the main causes for the decline of these ecosystems, while water bodies only occupies 0.054% same that have experienced a loss of wetlands lost by 0.004% during these 3 periods of study.
