The Green Infrastructure Assessment System (GIAS) and its applications for urban development and management

摘要: Adverse changes of the landscape resulting from diverse human activities have consequently caused quality decline and functional degradation natural landscape, endangering habitats various species. Meanwhile, technical advancements in area spatial analysis including GIS remote sensing enable many kinds easy-to-quantify indices. Although some systems were developed to support assess indices, developing for practical decision-making planning was insufficient. In this study, GIS-based Green Infrastructure Assessment System (GIAS) integrated assessment ecological values use management based upon indices sets that are mainly represented as structure, function, dynamics landscape. order verify effectiveness system, two case studies involving city Namyangju, northeast Seoul, conducted by applying GIAS (1) macro scale (2) micro scale. The study results demonstrate capability a tool perform concrete performance both on scale, its applicability stages planning. By utilizing GIAS, frequent human-induced impacts development projects can be examined advance, proactive alternatives prepared. addition, effective scientific systematic green infrastructure achieved.
