Abstract
In this study, an evaluation method was proposed to determine the restoration section in the riverine ecobelt project. The target river for this study is the Hongcheon river in Kangwon-do. The Hongcheon river of 96 km was divided longitudinally into subsections of 2 km. The analysis through map and aerial photograph as well as field surveys were performed in 48-sub-sections. The fragmentation items were classified into connectivity and ecological functionality. The connectivity fragmentation was also divided into two items: the area discontinuity of the land use and the line discontinuity of river bank and road. Also, the ecological functional fragmentation was evaluated by using the items of river channel, river bed, vegetation, and the obstruction of river flow. These items was modified from those in the previous literature. From map analyses and field surveys, the fragmentation score was kept with each items in 48 sub-sections of Hongcheon river. The fragmentation rate was made from the total score in each section. The results showed that sections from F1 to G2 was evaluated to have high rates of all connectivity and functionality fragmentation of 1st or 2nd rate. Other sections have high connectivity fragmentation of 2nd rate, but low functional fragmentation. Thus, these sections are evaluated to be excludible in restoration site. This study seems to make a contribution to evaluate the fragmented sections for the riverine ecobelt project.
