Solute transport from unfrozen to frozen soil was verified, and change in the soil freezing point and freezing rate depending on the solute transport were clarified as well as condensation of solute into unfrozen water in the frozen soil. When water infiltrate into dry frozen soil, five temperature regions were appeared. And, organic decomposition and nitrification in soil under the frozen soil was investigated. It was suggested that soil water flow enhance the mineralization and nitrification in the soil. For frost heaving, effects of anisotropy of groundwater supply route to freezing front, and solute and foreign substances in the soil were elucidated. We also proposed ideas to improve soil freezing model, such as non-equilibrium freezing and thawing of soil water and feasible surface boundary conditions.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2017年度～2021年度科学研究費補助金(基盤研究(B))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"17H03888","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"item_8_text_65","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"出版タイプ","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":"渡辺, 晋生","creatorNameLang":"ja"},{"creatorName":"Watanabe, Kunio","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"武藤, 由子","creatorNameLang":"ja"},{"creatorName":"Muto, Yoshiko","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-12-22"}],"filename":"2023RP0085.pdf","filesize":[{"value":"600 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://mie-u.repo.nii.ac.jp/record/2000265/files/2023RP0085.pdf"},"version_id":"cdd64e87-3e35-4545-8997-48d5da37a0bc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"凍土","subitem_subject_scheme":"Other"},{"subitem_subject":"気候変動","subitem_subject_scheme":"Other"},{"subitem_subject":"溶質移動","subitem_subject_scheme":"Other"},{"subitem_subject":"浸潤","subitem_subject_scheme":"Other"},{"subitem_subject":"地表面過程","subitem_subject_scheme":"Other"},{"subitem_subject":"有機物分解","subitem_subject_scheme":"Other"},{"subitem_subject":"硝化","subitem_subject_scheme":"Other"},{"subitem_subject":"凍上","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"環境変化に伴う土壌凍結層の盛衰と凍結層下の物質循環機構の解明と予測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"環境変化に伴う土壌凍結層の盛衰と凍結層下の物質循環機構の解明と予測","subitem_title_language":"ja"},{"subitem_title":"Fate of frozen soil layer under environmental changes, and the dynamics of water and solute in soil under the frozen soil","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1701929361491"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-12-22"},"publish_date":"2023-12-22","publish_status":"0","recid":"2000265","relation_version_is_last":true,"title":["環境変化に伴う土壌凍結層の盛衰と凍結層下の物質循環機構の解明と予測"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2024-09-24T05:43:48.005576+00:00"}
