Regeneration system of oak wilt disease stand for large-sized wild life

对栎树枯萎病造成的林隙内的再生状态进行了研究，并在航拍图上绘制了林隙周围山毛榉和其他栎树的潜在种子树树冠图。绘制了重要的营养地图，包括山毛榉和橡树的橡子，并在树冠地图上分层。通过对比不同林隙大小下幼树的生长情况，评价林隙大小对栎树死亡后再生的影响。在此基础上，对大型野生栎树枯萎病苗的再生体系进行了探讨。

Regeneration state in the gaps which were created by oak wilt disease was researched, and crown maps of potential seed trees of beech and oak other than beech around the gaps were drawn on an aerial photograph. Important nutrients maps including acorns of beech and oak were drawn and were layered on the crown maps. Effect of gap size on the regeneration after oak death was evaluated by comparing growth of young trees in the different sizes of gaps. On the basis of these results, regeneration system of oak wilt disease stand for large sized wild life was discussed.
