Assessment and connection method of fragmentary urban green space using gravity model

Abstract

This research presents the connecting method for the ecological network among the selected areas through the evaluation of the connectivity of the classified urban green space in Seoul. The study was divided into two; 1st stage of the classification of the types of greens and 2nd stage of the evaluation of connectivity. In the stage of classification of the type of the greens, the research evaluated the diversity of the vegetation and the value of the possibility of inhabitation of wild birds and then, classified the greens into a core green, which is a patch, base green, and connecting or stepping stone-type green, which is a corridor, in aspect of the landscape ecology. In the evaluation of connectivity, the research also selected and classified the areas for ecological network and suggested the connecting method by conducting the evaluation based on a gravity model with indexes such as area index, conference index, and fractal index, in order to find the relationship between the greens. © 2012 Springer-Verlag.
