In\neach forest canopy, we measured seasonal variations in CO2 flux, radiation environment,\nand visible–near-infrared spectral reflectance during 1 or 2 growing seasons.Wecalculated e\nas gross primary production (GPP) divided by the difference between incoming and reflected\nphotosynthetically active radiation (PAR). VIs and e under clear skies were averaged between\n11:00 and 13:00 JST and their relationships were analyzed.\nIn the larch forest, all calculated VIs were positively correlated with e, and the highest\ncorrelation was that with CCI. Because of effects of extreme reduction in PRI in autumn\nwith needle yellowing, the correlation of e and PRI was relatively small in this forest. In the\ncypress forest, on the other hand, no significant correlation was found except with PRI and\nCCI. The highest correlation in this forest was that with PRI, suggesting that the leaf\nbiomass-related VIs based on near-infrared reflectance are not sufficient for estimating e of\nevergreen forest. In the mixed forest, with relatively sparse vegetation cover, all VIs were\nsignificantly correlated with e, but the best correlation was that with SAVI, possibly owing\nto the reduction in the effect of the reflectance from background soil. Correlation analysis\nof the pooled data from all forests showed the highest correlation between e and PRI.\nThese results indicate that PRI is an effective VI in the remote estimation of e in both\ndeciduous and evergreen forests, although there are some sensitivity differences between\nvegetation types.","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/99978"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.agrformet.2007.11.006","subitem_relation_type_select":"DOI"}}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2007 Elsevier B.V."}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0168-1923","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10499788","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nakaji, Tatsuro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ide, Reiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takagi, Kentaro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kosugi, Yoshiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohkubo, Shinjiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishida, Nasahara Kenlo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saigusa, Nobuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oguma, Hiroyuki"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-19"}],"displaytype":"detail","filename":"AFM-148_5.pdf","filesize":[{"value":"499.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AFM-148_5.pdf","url":"https://tsukuba.repo.nii.ac.jp/record/16609/files/AFM-148_5.pdf"},"version_id":"d64ebed8-93bd-409d-b595-b87bb517b81d"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Utility of spectral vegetation indices for estimation of light conversion efficiency in coniferous forests in Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Utility of spectral vegetation indices for estimation of light conversion efficiency in coniferous forests in Japan"}]},"item_type_id":"5","owner":"1","path":["866","560"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-07-16"},"publish_date":"2008-07-16","publish_status":"0","recid":"16609","relation_version_is_last":true,"title":["Utility of spectral vegetation indices for estimation of light conversion efficiency in coniferous forests in Japan"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2023-07-12T05:23:17.670027+00:00"}
