This study used the new multifunctional vegetation network which created and developed by Multifunctional Materials Company in Japan, to take the experiment of erodibility and plant invasion of growth on the steep slopeland surface at the first experimental site in Pingtung University of Science and Technology with slope 60% and slope length 22 meters. This experiment include observed the runoff after heavy rainfall, soil erosion, slope stability and Bermuda grass growth situations in the outdoor situation, and laboratory experiment which investigated the permeable, breathable and moisture insulation condition, and compared the inference of plant seed germination rate and erodibility by different vegetation network materials. Hope to provide the references from this experiment result on future control work planning and project setting.
