The area of open forest has expanded in 1997 compared to those in 1971, however, decrease in forest area was not observed. It was the same tendency both in upland and lowland. On the other hand, cultivated area in lowland first expanded during 1971 to 1993, then tended to decrease after.\nThe population was gradually increased both in upland and lowland villages. Thus expansion of cultivated land from 1971 to 1993 cannot be explained by population increase. It is thought to be a socially unstable period right after the revolution. One of the factors for the expansion of the cultivated area is the agricultural collectivization held only in lowland, which lead to slush and burn to supplement rice shortage.\n","subitem_description_type":"Abstract"}]},"item_10009_end_page_10":{"attribute_name":"終了ページ","attribute_value_mlt":[{"subitem_end_page":"184"}]},"item_10009_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"総合地球環境学研究所　研究プロジェクト4-2"}]},"item_10009_record_name_7":{"attribute_name":"図書名","attribute_value_mlt":[{"subitem_source_title":"2004年度　生態史プロジェクト報告書"}]},"item_10009_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"総合地球環境学研究所"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.chikyu.ac.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"生態史プロジェクト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.chikyu.ac.jp/ecohistory/top_jp.htm","subitem_relation_type_select":"URI"}}]},"item_10009_start_page_9":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"177"}]},"item_10009_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"安田, 理恵"},{"creatorName":"ヤスダ, リエ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"463","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"富田, 晋介"},{"creatorName":"トミタ, シンスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"348","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"縄田, 栄治"},{"creatorName":"ナワタ, エイジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"337","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"河野, 泰之"},{"creatorName":"コウノ, ヤスユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"330","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasuda, Rie","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"464","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TOMITA, Shinsuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"84","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAWATA, Eij","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"339","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kono, Yasuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"331","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":"2016-08-23"}],"displaytype":"detail","filename":"report200421.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ラオス北部山地における土地利用変容－パック川源流域を事例として－","url":"https://chikyu.repo.nii.ac.jp/record/482/files/report200421.pdf"},"version_id":"3b002062-333e-4fc9-8b0f-7e06069995b3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"土地利用｜リモートセンシング｜焼畑","subitem_subject_scheme":"Other"},{"subitem_subject":"Landuse｜Remotesensing｜Shifting cultivation","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"book","resourceuri":"http://purl.org/coar/resource_type/c_2f33"}]},"item_title":"ラオス北部山地における土地利用変容－パック川源流域を事例として－","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ラオス北部山地における土地利用変容－パック川源流域を事例として－"},{"subitem_title":"Analysis of the spatial patterns of land use in the mountainous Northern Laos using remote sensing data ‒ A case study in the watershed of Phak-river ‒","subitem_title_language":"en"}]},"item_type_id":"10009","owner":"14","path":["152"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-23"},"publish_date":"2016-08-23","publish_status":"0","recid":"482","relation_version_is_last":true,"title":["ラオス北部山地における土地利用変容－パック川源流域を事例として－"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-06-20T16:47:54.759117+00:00"}
