We calculated pollen (Ce+Fa/Po+Fa) ratio of 321 samples and we identified the fungal spores of 216 sedimentary samples to reconstruct changes in cultivation and grazing intensity over the past ~2,000 years in northern China. Time-series analysis reveals that the arable farming phases had a longer periodicity than the grazing phases, possibly because of the greater resilience of the former to climate change and the attachment of agriculturalists to their land. Our findings potentially help improve our understanding of the impact of land use on soil degradation. The data is stored in Excel format.","doi":"10.11888/Paleoenv.tpdc.271291","projection":"","language":"zh","share_type":"online","east":112.23,"west":112.23,"south":38.9,"north":38.9,"scale":null,"crs":null,"filesize":0.06,"share_policy":"a","ts_created":"2021-05-18T07:22:52.181327+08:00","doi_type":"拥有自主知识产权","ts_updated":"2021-05-30T10:20:22.910000+08:00","time_description":"Past ~2000 years","datas_group":3,"time_description_en":"Past ~2000 years","data_format":null,"project":[11],"specials":[],"cite":null,"review_status":5,"review_invite":[],"review_editor":{"id":21054,"last_login":"2022-04-10T10:49:12.540341+08:00","username":"tingting","email":"panxd@itpcas.ac.cn","is_active":true,"is_staff":true,"user_name":"潘小多"},"data_sources":null,"temporal_resolution":"Yearly","spatial_resolution":"-","license":"Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","fund":[],"subtopics":{"metadata":"d179a6a3-2946-4b60-9b5b-40681a0ae238","three_pole":null,"third_pole":null},"username":"潘小多","review_time":null,"protected_duration":null,"protected_describe":null,"is_important":false,"hit_count":673}
