| Research Abstract |
The object of this study is to know the "Effect of species diversity on invasion of introduced forage plants"through field survey and field experiments.
1, This grassland has been maintained as habitat of native horse that is one of national monument of our country. Few years ago, Komatugaoka and Ougiyama was dominated by native plants such as Zoysia japonica. Komatugaoka changed from native grass to alien grass dominated grassland for over 10 years. But, Ougiyama was not changed.
2, The species diversity of native plants was higher Ougiyama than Komatugaoka. Nitrogen content of soil of Komatugaoka was higher than Ougiyama.
3. The alien grass can't grow in a pot of high species richness and high density of native plant.
