Research on the multiple functions of the windbreak in Tokachi

为了防止TOKACHI地区的防风林减少，需要科学地证明防风林的多种功能。因此，作为居住地的意义，不仅作为农田保护机构的有效性的防风林，站在旁边的领域，这是特别是个人财产管理，但现场保护和小动物的事情进行了研究-此外，这项研究是共同完成的防风林延续的目的。为了达到这一目的，对小动物防风林的利用进行了调查。此外，在防风林更新中，根据树的高度推测树龄，制定了防风林更新的配置方案。由此获得了以下知识：虽然飞鼠栖息在分割的森林中，但通过滑翔运动，防风林被用作走廊，显然可以迁移到其他森林。此外，还对松鼠、蝙蝠等小动物进行了行动调查。对留室进行了防风林树高与树龄关系的调查。根据这些数据，我们制作了树型，树龄，防风保护领域，并合理安排防风林的TOKACHI地区的专题地图。

In order to prevent reduction of the windbreak of a TOKACHI district, it is required to prove the multiple functions of a windbreak scientifically. therefore, the thing for which the meaning as a place of residence of not only the validity as a farmland preservation institution of a windbreak that stands beside the field which is especially personal property management but scene preservation and small animals is studied - moreover, this research was collectively done for the purpose of windbreak continuation. In order to attain this purpose, investigation about use of the windbreak of small animals was conducted. Moreover, for renewal of windbreak proper, the age of a tree was guessed from tree height, and the renewal arrangement plan of windbreak proper was created.As a result, the following knowledge was acquired.Although flying squirrel inhabited the divided forest, by carrying out glide movement, the windbreak was used as a corridor and it became clear that moving to some of other forests is possible. Moreover, action investigation to small animals, such as a squirrel and a bat, was also conducted.Investigation of the tree height of a windbreak and the relation of the tree age carried out for Memuro. Based on these data, we created the topical map of tree-type, tree-age, the protection-against-wind domain, and proper arrangement of a windbreak of the TOKACHI district.
