Abstract
We compared seedlings growth from (1)soil seed bank and commercial seeds (2)cultivative base of organic matter and that of organic matter with mineral soil in revegetation methods. The results of monitoring for 4 years were as follows; 1) species richness of soil seed bank of two revegetation methods were 2.8 and 5.2 times more than those of commercial seeds. 2) number of seedlings were 6.0&sim:17.5 per 1m2 in soil seed bank plots. And indices of biomass 4 years after construction in soil seed bank were similar to those of commercial seeds. It would be possible to make diverse both landscape and plant community by soil seed bank.
