초록

Recently, geofiber(polyester) reinforced soil was added on soil-seed mixture spray to control erosion and to improve vegetation growth on rocky slope sites. This research was conducted to compare vegetation effects and soil hardness on three types of soil-seed mixture spray on stone gabion river bank [A type：soil-seed mixture spray underlying 30㎝ thick sand with geofiber(geofiber reinforced soil system), B type：soil-seed mixture spray underlying 30㎝ thick sand without geofiber, C type：soil-seed mixture spray]. Evaluation were made concerning vegetation coverage, soil hardness and moisture content.
The results of this study showed that A type system was effective for the growth of vegetation and soil hardness when compareed to B type and C type. A type and B type showed higher covering rate than C type on stone gabion river bank, and especially A type showed the highest covering rate. Soil hardness and water content were high on A type vegetation system compared to B type and C type.
We noted that high soil hardness and high moisture content with geofiber(geofiber reinforced soil system) were effective both to control erosion from water current impact and to be high coverage and species of vegetation on stone gabion river bank.
