内容記述
The stand structure of deciduous broad-leaved forest in warm temperate zone which had been managed as the coppice forest supplying the wood for fuel and charcoal was investigated and discussed in order to establish a new management method for supplying the log for shiitake (Lentinus edodes SINGER) culture. In natural, Quercus serrata MURRAY, one of the most useful species for the shiitake culture, are often most dominant at the upper part of the slope, composing over 90% of the total basal area of the breast height and over 80% of trees in the stand. As this species has the most narrow crown, the greatest number of trees can be grown on an area. On the other hand, there are many places, where few Quercus serrata and many other less useful species for shiitake culture are present. In consideration for the management method of the coppice forest supplying the log for shiitake culture, it is the problem how to manage these unuseful places in the stands.
