Abstract:: Because of the topography, geology and climate, so there are quite many landslides and soil loss in Taiwan. Furthermore, people exceed the land utilized limit for overdevelopment and the result should cause much more sediment disasters question. In order to accelerate national land reconstruction, vegetation engineering of soil and water conservation often put adhesive into the project of sprayed work to make plant seed effective staying and growing, and there is the purpose of protecting slope land surface for soil erosion. This research regard common red soils of subtropical area as testing samples, spray three kinds adhesive to carry on 60 min test with the rainfall intensity 50, 80, 110 mm/h and slope gradient 16.7°, 21.8°, 28.8°. The results show that soil spraying with polymer adhesive treatment can remain stable reodibility more than other two kinds material. Soil spraying with acrylic resin treatment has more soil erosion in high strength rainfall. Soil spraying German bitumen emulsion treatment has more soil erosion in steep slope conduction.
