Resumen: El uso del suelo urbano en las ciudades de hoy está más fragmentado
que nunca. La urbanización crea un exceso de construcción, falta de
vegetación y fachadas sombrías. También se asocia con una disminución
de las especies y la diversidad trófica. Las preocupaciones recientes
sobre el calentamiento global han llevado a una visión más holística de
la planificación del medio ambiente. Por ello, se han creado espacios
públicos abiertos con el fin de mejorar la salud y la calidad de vida de
las personas, así como proporcionar hábitat a diferentes especies dentro
de las zonas urbanas. La variación de áreas verdes y hábitat ha sido
pobremente documentada. Esto motiva una investigación sobre cómo la
media y la varianza del porcentaje de áreas verdes varía con la
distancia y el tipo de área. Esto se hace mediante el diseño de un
método utilizando imágenes satelitales en tres ciudades: Beijing, Lima y
Londres.
Urban land use in today’s cities is more fragmented than ever. Urbanisation creates overbuilding, lack of greenery and grim facades. It is also associated with a decline in species and trophic diversity. Recent concerns about global warming have led to a more holistic view of planning for the environment. As a result, public open spaces have been created with the purpose of improving people’s health and quality of life, as well as providing habitat for different species within urban areas. Variation of green areas and habitat has been poorly documented. This motivates an investigation on how the mean and variance of the percentage of green areas varies with distance and area type. This is done by designing a method using satellite imagery in three cities: Beijing, Lima and London. It was found that the mean of green percentage and distance varied with city and with area type. In Beijing, green spaces decline to a similar plateau. In Lima, green space decreases very slightly in residential areas but rises slightly in commercial centres. In London, there is a rise to asymptote in residential areas while in the commercial ones, there is an apparent rise. The relationship between the variance of green space and distance varied with city as well. In Beijing, the variance declines exponentially with distance and decreases slightly in Lima and London. This means that the different proportion of green areas will have different effects on the biodiversity in each city. This is based on the connectivity represented by the variance and mean percentage while following principles of island biogeography.
