抄録

In order to study the methods of establishing the evergreen broadleaved forest, which is a relatively developed vegetation in the plant succession series on artificial slopes of poor sites, we tested the dense planting of Quercus glauca and mixed planting of fertilizer tree (Alnus Sieboldiana). Seven years after planting, tree canopy is almost closed in each plot, and results at present are as follows.<BR>(1) Dense planting of small nursery trees is more profitable than sparse planting of big ones.(2) Effects of fertilizer tree on the growth of Quercus glauca are not clear. but mix planting on the fill-in slopes resulted in a great deal of standing mass.(3) Land treatment (cut or fill) is the most effective factor for the size of Quercus glauca, and initial plant size is less effective.
