The effects that the geo-textile mulching sheet has influenced on the runoff-water, suspended solid, sediment yield and vegetation growth are as follows in artificial slope 1. The flora of plots was composed 12 families, 21 genera, 20 species, 2 varieties, total 22 taxa. 2. The geo-textile mulching sheet is effective on increasing of introduced vegetation population, number of species and vegetation coverage, but just only with the mulching sheet it shows limit of was somewhat difficult to expect the increase of the existence ratio. 3. The amount of runoff-water increased in proportion to rainfall and at mulched plots were about 1/15.5 as decreased as that of un-mulched plots. 4. The amount of suspended sediment increased in proportion to rainfall and at mulched plots were about 1/47 as decreased as that of un-mulched plots. 5. Also, the amount of sediment yield increased in proportion to rainfall and at mulched plots were about 1/151 as decreased as that of un-mulched plots. so, multi-function- filter is very effective on prevention of soil erosion.
