Abstract

Landscape changes for 20 years betwen 1981 and 2001 in the Wangsuk stream basin locatedon the central Korea were investigated on the basis of physiognomic vegetation map made from the aerialphotograph interpretation and field check. Changes of landscape structure were noticeable in agricultural fieldinto the institutional agriculture dominated landscape change, although urbanization also contributed to suchchange. The former change due to change of food production structure originated from socio-economicdevelopment during this period and the latter to the overpopulation of Seoul. As energy sources for heating andcooking, fertilizer, and fodder for livestock transform from plant materials to fossil fuel, manufactured one, andgrain, succession of forest escaped from direct human disturbance dominated change of landscape structure inforested land. Differently from the positive landscape change in the upper area, change in the lower areathe Wangsuk stream basin would influence water quality of the stream. In order to realize sustainable land-useagainst such environmental degradation, systematic environmental management based on landscape cologicalperspective such as an eco-plan for creating riparian vegetation belt, which is under preparation by Ministryof Environment, was recommended.
