In July 2007, forest surveys were conducted along a south–north transect (150°W) to profile the ecotone from boreal forest to tundra in Alaska. In situ parameters were measured in 29 forests by a combination of the Bitterlich angle-count sampling method and the sampled-tree measuring method. These in situ values were compared with the backscatter intensity of ALOS/PALSAR. A strong positive logarithmic correlation was found between the backscatter intensity and the forest AGB, with the correlation being stronger in the HV than in the HH polarization mode. No obvious saturation was found in the sensitivity of the HV mode backscatter intensity to the forest AGB up to 120.7 Mg ha^<−1>. Similarly, a robust sensitivity was found in the HV backscatter intensity to both tree height and DBH, but weak sensitivity was observed for tree density. The regression curve of HV backscatter intensity to the forest AGB appeared to be intensified by the uneven forest floor, particularly for forests with small AGB. The geographical distribution of the forest AGB was mapped, demonstrating a generally south-rich and north-poor forest AGB gradient.","subitem_description_type":"Abstract"}]},"item_10001_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"　アラスカにおける亜寒帯林の地上部バイオマス(AGB)や，そのほかの森林物理量に対する，ALOS/PALSARの後方散乱強度による推定の可能性を評価した。2007年7月にアラスカの亜寒帯林からツンドラへと至る西経150度に沿った南北トランゼクトにおける29の森林の森林物理量を得，ALOS/PALSARの後方散乱強度と比較した。その結果，HVモードの後方散乱強度には，森林AGB，平均樹高，平均胸高直径との間に対数関数の強い関係が認められた。得られた回帰式(HVモード)を用いて推定された森林AGBを地図化したところ，南部で大きく北部で小さくなるような南北傾度が描き出された。","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立極地研究所"}]},"item_10001_relation_12":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"110009579490","subitem_relation_type_select":"NAID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2013.03.001"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1016/j.polar.2013.03.001","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12240481","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Suzuki, Rikie"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kim, Yongwon"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Reiichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suzuki, Rikie","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kim, Yongwon","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Reiichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Synthetic aperture radar (SAR)","subitem_subject_scheme":"Other"},{"subitem_subject":"Bitterlich method","subitem_subject_scheme":"Other"},{"subitem_subject":"Ecotone","subitem_subject_scheme":"Other"},{"subitem_subject":"Black spruce","subitem_subject_scheme":"Other"},{"subitem_subject":"White spruce","subitem_subject_scheme":"Other"},{"subitem_subject":"Allometry equation","subitem_subject_scheme":"Other"},{"subitem_subject":"Synthetic aperture radar (SAR)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Bitterlich method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Ecotone","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Black spruce","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"White spruce","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Allometry equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Sensitivity of the backscatter intensity of ALOS/PALSAR to the above-ground biomass and other biophysical parameters of boreal forest in Alaska","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sensitivity of the backscatter intensity of ALOS/PALSAR to the above-ground biomass and other biophysical parameters of boreal forest in Alaska"},{"subitem_title":"Sensitivity of the backscatter intensity of ALOS/PALSAR to the above-ground biomass and other biophysical parameters of boreal forest in Alaska","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"27","path":["1345"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-10-16"},"publish_date":"2014-10-16","publish_status":"0","recid":"10129","relation_version_is_last":true,"title":["Sensitivity of the backscatter intensity of ALOS/PALSAR to the above-ground biomass and other biophysical parameters of boreal forest in Alaska"],"weko_creator_id":"27","weko_shared_id":27},"updated":"2023-07-25T16:21:29.747589+00:00"}
