The vegetation in and around the Tokyo University Forest in Yamanakako was classified into four types (VT A-D, Fig. 1). Breeding bird species diversity (BSD; Tab. 1) was estimated in each VT. Two vegetation structure measurements, foliage height diversity (FHD) and crown patchiness (CP) (Fig. 4-6), were estimated from VSV. Indices of BSD and FHD were calculated with Shannon-Wiener's H'(H'=-Σipi・log2 pi) and CP with Morishita's Iδ(Iδ=nΣiXi(Xi-1)/N(N-1)). With CP, both vertical and horizontal structure can be estimated at the same time. The relationship between BSD and FHD, or BSD and CP was examined among the four VT. FHD was found very sensitive to the hetelogeneity within a same VT habitat (B1 and B2 in Fig. 4 and 5). FHD of five-foliage-layer was decided available (Fig.5), but FHD of every 1m deep layer (Fig.4) was not. Except VT D, which was remarkably open vegetation (Fig. 2 and 3), BSD and FHD of five-foliage-layer correlated significantly (r2=.92, p <.05, BSD=3.62・FHD-1.89; Fig. 5). CP of VT D was much larger than those of the others (Fig. 6). Then it was suggested that CP is available to distinguish the qualitative and large differences among habitats, and that FHD, on the other hand, among relative and similar ones. The author discussed about the conbination anlysis of BSD and vegetation structure with CP, FHD, plant species and so forth, using the figures of vertical section of vegetation.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55492","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ISHIDA, KEN"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学農学部林学科"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石田, 健"}],"nameIdentifiers":[{"nameIdentifier":"55491","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh076009.pdf","filesize":[{"value":"759.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh076009.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25582/files/esrh076009.pdf"},"version_id":"f21fdb81-7722-448f-bf26-6441e8234191"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"植生断面図によって評価した森林の空間構造と鳥類の多様性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"植生断面図によって評価した森林の空間構造と鳥類の多様性"}]},"item_type_id":"4","owner":"1","path":["2590","2589"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25582","relation_version_is_last":true,"title":["植生断面図によって評価した森林の空間構造と鳥類の多様性"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:59:46.439294+00:00"}
