| description | This article presents a characterization of the areas likely to integrate a Green Infrastructure (GI) for the Tunja city at local scale and spatial analysis is mainly applied to the land cover and land use of the study area. To identify the areas that could be integrated into the GI, four thematic dimensions were first zoned (ecological connectivity, multifunctionality, ecological status and accessibility to the population); they were later normalized on a scale of 1 to 10 to make them comparable; the dimensions were combined by an Analytic Hierarchy Process (AHP) and finally those areas whose pixel values were above the third quartile were selected in the integration of the dimensions. The zoned dimensions the following weights were obtained: ecological connectivity (48%), multifunctionality (30%), ecological status (13%) and accessibility to the population (9%). It was found that the main areas likely to integrate into the GI are concentrated in the western fringe of the city; however, the northwestern area has a greater fragmentation and lower ecological status than the southwestern zone (which refers mainly to the Protective Forest Reserve El Malmo). Likewise, several areas or patches were identified to the south of the city (referring mainly to wooded areas and presence of wetlands) as well as small wooded areas in the urban perimeter, but with greater isolation among the other areas of GI. Within the urban perimeter the zoning of areas that could be integrated into a GI was practically null. |

Within the urban perimeter the zoning of areas that could be integrated into a GI was practically null. Se presenta una caracterización de las áreas susceptibles de integrarse a la Infraestructura Verde (IV) del municipio de Tunja a una escala local y aplicando principalmente análisis espacial sobre las coberturas y usos del suelo de la zona de estudio. Para identificar las áreas susceptibles de integrarse a la IV se zonificó en primer lugar cuatro dimensiones temáticas (conectividad ecológica, multifuncionalidad, estado ecológico y accesibilidad a la población); posteriormente se normalizaron en una escala de 1 a 10 para hacerlas comparables; enseguida se combinaron las dimensiones mediante un Proceso de Análisis Jerárquico (AHP, siglas en inglés) y finalmente se seleccionaron aquellas zonas cuyos valores de pixel estaban por encima del tercer cuartil de datos en la integración de las dimensiones. En las dimensiones zonificadas se obtuvieron los siguientes pesos: conectividad ecológica (48%), multifuncionalidad (30%), estado ecológico (13%) y accesibilidad a la población (9%). Se encontró que las principales áreas susceptibles de integrarse a la IV se concentran en la franja occidental del municipio; sin embargo, la zona noroccidental presenta una mayor fragmentación y menor estado ecológico que la zona suroccidental (la cual hace referencia principalmente a la Reserva Forestal Protectora El Malmo). Igualmente se identificaron varias áreas o parches al sur del municipio (haciendo referencia principalmente a zonas arboladas y presencia de humedales) así como pequeñas áreas arboladas en el perímetro urbano, pero con un mayor aislamiento entre las demás áreas de IV. Dentro del perímetro urbano la zonificación de áreas susceptibles de integrarse a una IV fue prácticamente nula.
