Abstract

Recently, for places with poor vegetating environment, such as slopes made of weathered soil or rocks, erosion tranquilizers, coverings and composite fertilizers have been mixed with seeds and sprinkled onto soil. Also, these plant revegetations have been mixed with nets and used to strengthen cohesion. However, this technique often obstructed plant growth and caused pollution because of not decomposing nets. This study has tested influence on plant revegetation B for slope of weathered soil and rocks and decomposition of naturally decomposing polyester filament yarn. In result, it was showed that plant revegetation B does not harm environment in case of applying it to soil slope and enhance protection capacity of slopes as time goes by. Also, naturally decomposing polyester filament yam was analyzed its physical properties with the passage of time and was known that naturally decomposing polyester filament yarn transformed into a structure easy to decompose by hardening. Thus it is considered that the revegetation method used this study was very effective method for plant establishment and stability of slope.
