本数据集为黑河上游葫芦沟流域土壤呼吸原位观测数据集，观测时段为2023年4月至2025年4月，下垫面类型为高寒草原，属于季节冻土区，海拔3028m。数据集包含经过质量控制和缺失值插补的土壤呼吸时间序列以及同步观测的5cm土壤水分和土壤温度，时间尺度为日尺度，观测对象为CO2，包括土壤总呼吸、异养呼吸以及生态系统净碳交换。", "ds_source": "", "ds_process_way": "", "ds_quality": "", "ds_acq_start_time": "2023-04-01 00:00:00", "ds_acq_end_time": null, "ds_acq_place": "葫芦沟流域", "ds_acq_lon_east": 99.87777777777777, "ds_acq_lat_south": 38.265, "ds_acq_lon_west": 99.87777777777777, "ds_acq_lat_north": 38.265, "ds_acq_alt_low": 3028.0, "ds_acq_alt_high": 3028.0, "ds_share_type": "apply-access", "ds_total_size": 550081, "ds_files_count": 0, "ds_format": "*.xlsx", "ds_space_res": "", "ds_time_res": "日", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "b5d7972e-b789-4d3f-a12b-ccf81051eaa2.JPG", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "None", "ds_from_station": null, "organization_id": "52b7b79b-860c-49a5-9083-9a70cf8bed5a", "ds_serv_man": null, "ds_serv_phone": null, "ds_serv_mail": null, "doi_value": "", "subject_codes": [ "170", "170.4510" ], "quality_level": 0, "publish_time": "2026-06-09 11:50:06", "last_updated": "2026-06-09 11:50:06", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.ncdc.soil.db7448.2026", "i18n": { "en": { "title": "Soil respiration dataset of alpine grassland in the Hulu catchment at upstream of Heihe River (2023-2025)", "ds_format": "*.xlsx", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "
This dataset consists of in-situ soil respiration observations from the Hulu catchment in the upper reaches of the Heihe River, spanning from April 2023 to April 2025. The underlying surface type is alpine grassland, located in a seasonally frozen soil region at an elevation of 3028 m. The dataset includes soil respiration time series with quality control and missing value imputation, along with synchronous measurements of 5 cm soil moisture and soil temperature. The temporal resolution is daily, and the observed variables are CO2-related parameters, encompassing total soil respiration, heterotrophic respiration, and net ecosystem carbon exchange.", "ds_time_res": "", "ds_acq_place": "Hulugou Basin", "ds_space_res": "", "ds_projection": "", "ds_process_way": "", "ds_ref_instruction": "" } }, "submit_center_id": "ncdc", "data_level": 0, "recommendation_value": 0, "license_type": "https://creativecommons.org/licenses/by/4.0/", "doi_reg_from": "reg_local", "cstr_reg_from": "reg_local", "doi_not_reg_reason": null, "cstr_not_reg_reason": null, "is_paper_in_submitting": false, "belong_to_nieer": false, "ds_topic_tags": [ "土壤呼吸", "高寒草原" ], "ds_subject_tags": [ "地球科学", "自然地理学" ], "ds_class_tags": [], "ds_locus_tags": [ "高寒草原", "季节冻土" ], "ds_time_tags": [ 2023, 2024, 2025 ], "ds_contributors": [ { "true_name": "王肖波", "email": "wangxiaobo@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "韩春坛", "email": "hancht@lab.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "刘易文", "email": " liuyiwen@nieer.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "王肖波", "email": "wangxiaobo@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "韩春坛", "email": "hancht@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "刘易文", "email": "liuyiwen@nieer.ac.cn", "work_for": "西北生态环境研究院", "country": "中国" } ], "ds_managers": [ { "true_name": "刘易文", "email": "liuyiwen @nieer.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "category": "冻土" }
