Cause and consequence of landscape fragmentation and changing disturbance by socio-economic development in mountain landscape system of South Korea

--Through the statistics and the analysis of landscape map,changes of lands-use regime and landscape structure during 20 yearswere investigated in the agriculture-forestry complexed mountainlandscape system of Yangdong-Myon, Yangpyung-Gun in the centralKorea. Landscape changes of this region was inter-related to therecent socio-economic development of rural life. Utilization ofbiomass and other traditional forest management were drasticallyabandoned in recent 10 years. Landscape analysis of maps showedthat the area of secondary vegetation that had been sustained byhuman-nature disturbance was decreased by use of plantation duringthis time. Those decreased areas were replaced to plantation forwood production and other purpose. Past area of woody speciesdominated in plantation also substituted to other species. Traditional human activity on secondary vegetation was disappeared. Consequently, the advanced management regimes such as newplantation and cultivation extending areas were increased inabandoned land.
