ABSTRACT

This study was focused on survival rate of river vegetation recently restored by different planting methods along with locations in the Hwangujicheon River from August 2008 to August 2009. The planting location was divided in three parts such as shoreline, slope and floodplain. The survival rate of each location was not much different significantly. The highest survival appeared in floodplain (59.79%) and then slope(49.47%) and shoreline(46.16%) were high in order. Little difference was observed among them. By comparison with planting methods, the shrub(86.67%) showed the highest survival rate than other netting(51.70%), pot(50.41%), plant reed(49.05%), rubble(27.92%). Over 50% of plants can be survived well except rubble. Even though percentage was varies with time lapsed, but it showed increasing tendency continuously. In particular both pot and shurb remarkably increased with time lapsed compared to early planting. As results of community index for the major types of species community(Phragmites communis, Salix gracilistyla, Miscanthus sacchariflous), the species richness tended to be decreased after initial states. In contrast, the sum of coverage, species diversity and evenness showed increasing tendency continuously. The highest species richness observed in the rubble when compared different planting methods. Sum of coverage is highest in the pot.
