THE DECLINE OF FOREST OWNER'S MIND AND REORGANIZATION OF FOREST RESOURCES POLICY

近年来，由于台风、鹿等灾害以及国内木材价格的下跌，森林所有者对森林管理的态度有所下降。我们可以在砍伐人工林后找到非人工林。我们对九州的林协合作社进行问卷调查，了解林主的森林经营情况。我们发现，尽管九州的林业活动非常活跃，但超过20%的砍伐森林没有被种植。以祁塔县祁塔南郡盆地和高知县Reihoku盆地为研究对象，研究了采伐后非种植的主要影响因素。因此，留下不种植的因素如下。首先是森林工人短缺。森林工人不断减少，年龄越来越大，森林所有者在砍伐森林后，由于劳动力短缺，无法自己植树。他们希望通过森林协会合作社或森林开发公社种树，但也因为森林劳动力短缺而无法实现。其次，由于木材价格下降和鹿群的破坏，人工森林砍伐后再造林无利可图。

Recently forest owner's minds for forest management have been declining through the damages by like a typhoon and deer, and the fall in price of domestic timber. We can find the non planted forest after felling artificial forest.We had a quetiOnnaire survey to forest association cooperatives in Kyushu, to know forest operations by forest owners. And we found more 20% of fallen forest have been not planted though forestry activity is very high in Kyushu.We investigated some forestry areas to study primary factors of leaving non planted after felling, in Qita Nangun Basin in Qita Prefecture and Reihoku Basin in Kochi Prefecture.As a result, factors of leaving not planted are following. First is shortage of forest workers. Forest workers have been declining and becoming older, so forest owner could not plant tree by themselves after felling their forest because of labor shortage. They would hope to plant tree by forest association cooperative or the Forest Development Corporation, but they could not do it because of forest labor shortage also.Second is that reforestation after felling of artificial forest is unprofitable, because of falling in timber price and damages by deer.
