Caracterización del paisaje de piedemonte identificando los cambios de cobertura vegetal Villavicencio, Meta, años 2000-2016

Abstract

In the present work, the characterization of the landscape was carried out in an area of piedmont associated with changes in plant cover affected by various anthropic, economic and legislative factors, in order to assess the state in which it is located and the process of changes in a 16-year multitemporality, as an input for the conservation creation of the piedmont of Villavicencio, Meta. In the present work an exercise of characterization of vegetation coverings of piedmont was carried out by temporary succession from the year 2000 to 2016 from an ecological and environmental approach, based on the established guidelines for the use and conservation of vegetation cover of the land use planning plan from the city of Villavicencio. Under the Corine Land cover methodology, we defined the categories and types of coverage that occur in a piedmont landscape, a territory that is constantly expanding, with important dynamics that are in contrasts of wide visibility. As a first step for the fulfillment of the objectives, the coverages present in the piedmont were identified and characterized in a temporality of 16 years; where for the development of the objective the use of satellite images and remote sensors will be used to determine the spectral signature for each coverage and generate a supervised classification for the grouping and location of each category. With the coverages established, landscape metrics of composition, form and connectivity were implemented, determining the distribution of vegetation cover, the fragmentation that they have presented and the connectivity for established temporality. As a last objective, areas of importance were determined with respect to the degree of fragmentation and transformation that occurs for each type of coverage, these zones are determined from a conditional model by various variables (metrics, classification, appropriate use, etc.), executed in a flow chart. Areas whose objective is to add as an input for the conservation, restoration or improvement of the visual quality of the piedmont area of Villavicencio. The results confirm the importance of identifying the changes in the foothills of the Piedmont as an element to consider in the conservation of vegetation cover in Villavicencio, Meta.
