ABSTRACT

This study was conducted to find out the possibility of seeding of Zoysia japonica and woody plants for the revegetation of rock-exposed-cutslopes by Natural Topsoil Restoration Methods(NTRM). The 5cm thick layer of artificial soil was attached at rock-exposed cutslopes for growth of Zoysia japonica and native woody plants by NTRM. The main results were summarized as follows.

1. Artificial soil attached at rock-exposed-slopes by NTRM was not eroded until recovered by Zoysia japonica and native woody plants. It shows extremely low soil erodibility.

2. One Year later after seeding, woody plants show 100% ground coverage. But, in early stage, they grew more quickly at northwest slopes than at southeast slopes.

3. In seeding of Zoysia japonica, it grew more quickly at southeast slopes than at northwest slopes. Also, it grew better at lower part of the slopes than at middle part of the slopes.

4. After one year from seeding, the height of Lespedeza cyrtobotrya and Indigofera pseudo-tinctoria were longer than any other plants. The next were Albizzia julibrissin, Lespedeza cuneata and wild flowers. The tree height of Rhus chinensis shows 28cm length, so it has enough possibility to be used for roadside revegetation works.

5. Lespedeza cyrtobotra and Indigofera pseudo-tinctoria show different importance values according to slope aspect. But, they show tendency to outweight the other plants at all slope aspects

6. Most of the plants seeded by NTRM were germinated well and they covered rock-exposed-slopes so quickly and effectively. Thus it leads to conclusion that the revegetation methods used in this experiment was a very effective methods to recover rock-exposed-slopes by seeding of zoysia jponica and native woody plants.

Key words : rock-exposed cutslopes, artificial soil, erodibility, importance value, Natural Top Soil, Restoration Methods
