The computer programs\nare based on the following assumptions: (1) Population grows exponentially,\nwith the equation Nt=No*evt; (2) there is an upper\nlimit to population size in a given area, termed carrying capacity\n(K); and (3) at the level K, population growth stops. In this program,\nwe divided Japan into nine regions, such that when population\nreaches the level K, the surplus migrates to other areas, according to\nprobablistic models.\nIn dealing with carrying capacity, we initially assign the constant\nM, a hypothetical population maximum for an area; subsequently\nM is converted to K as a consequence the impact of climate and\ntechnology.\nPollen analysis indicates significant climatic change during the\nJomon Period. This was precipitated by a warming trend, which\nbegan after the last glacial, and continued until about 6000 B.P.,\nfollowed by a cooling trend which lasted until about 2000 B.P.\nThis climatic wave caused significant change in the vegetation of the\nJapanese archipelago. In the East during the warming trend,\nconiferous forests were replaced by deciduous Fagus-Quercus forests,\ncomprised of a variety of nut-bearing trees, which constituted an\nimportant food source for the Jomon people. However, the nutbearing\ntrees are sensitive and often succumb in cold weather. Based\non these facts, we assume that carrying capacity increased during the\nwarming trend and decreased during the cooling trend in the regions\nof East Japan. In West Japan, however, Yasuda [1980] suggests\nthat during the warming trend the environment deteriorated owing to\ndry summers. So here we assume that carrying capacity declined\nduring the warming trend and then remained constant.\nThe technology of Jomon food production, including the tool\nelements used for hunting, fishing and gathering, are well known from\nan early stage in East Japan. Thus we assume that although tools must\nhave been refined and systematized as Eastern Jomon technology\ndeveloped, they were not powerful enough to influence carrying\ncapacity, because the system did not prevent population decline in the\ncooling period. By contrast, farming, the true technological innovation,\nintroduced from the Asian continent to Kyushu, changed\nJomon society into an agricultural one. In this simulation we stipulate\nthat when rice is introduced into a region it not only doubles the\nratio of population growth but also increases carrying capacity\n(five times).\nThe results were compared with earlier estimates [KOYAMA 1978]\nbased on the number of sites. Both data coincide well, especially\nwith respect to the population curve throughout the Jomon period.\nIn the East this curve shows a sharp increase of population until the\nMiddle Phase, where a rapid decline is observed (Late Phase). In\nthe West population remained almost constant throughout the entire\nperiod. During the Jomon, the distribution of pupolation was high\nin the East, whereas in the Yayoi it was high in the West—representing\na complete reversal between the two periods.","subitem_description_type":"Abstract"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15021/00004436","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立民族学博物館"}]},"item_9_publisher_34":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Museum of Ethnology"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00091943","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-180X","subitem_source_identifier_type":"ISSN"}]},"item_9_version_type_16":{"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":"小山, 修三"},{"creatorName":"コヤマ, シュウゾウ","creatorNameLang":"ja-Kana"},{"creatorName":"Koyama, Shuzo","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"杉藤, 重信"},{"creatorName":"スギトウ, シゲノブ","creatorNameLang":"ja-Kana"},{"creatorName":"Sugito, Shigenobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-11-19"}],"displaytype":"detail","filename":"KH_009_1_001.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KH_009_1_001.pdf","url":"https://minpaku.repo.nii.ac.jp/record/4444/files/KH_009_1_001.pdf"},"version_id":"f485c679-68da-4de9-919d-2ff2c3d7227d"}]},"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":"縄文人口シミュレーション","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"縄文人口シミュレーション"},{"subitem_title":"A Study of Jomon Population : Computer Simulation Analysis","subitem_title_language":"en"}]},"item_type_id":"9","owner":"17","path":["470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-16"},"publish_date":"2010-02-16","publish_status":"0","recid":"4444","relation_version_is_last":true,"title":["縄文人口シミュレーション"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T17:17:55.651730+00:00"}
