三江源地区位于青海省南部、青藏高原腹地，是长江、黄河和澜沧江（境外称湄公河）的发源地，素有“中华水塔”之称，发育在该地区的冰川是诸多江河的重要水源补给。本研究首先基于Landsat TM/ETM+/OLI/OLI–2遥感影像和DEM等数据，结合深度学习模型实现对不同时期（2000年、2005年、2010年、2015年和2020年）三江源地区冰川边界的初步自动提取。然后利用人工目视解译对其进行逐条检查与修订，并参考Randolph Glacier Inventory 7.0冰川编目数据和中国第二次冰川编目数据完善相关属性信息，得到该地区多期冰川边界数据集。最后采用冰川中流线方法提取该地区多期冰川长度数据。数据集包含三江源地区冰川编目矢量数据，三江源地区冰川长度数据2个文件。本数据集可作为三江源地区冰川变化和冰川对气候变化响应等研究的基础数据。", "ds_source": "", "ds_process_way": "", "ds_quality": "", "ds_acq_start_time": "2000-01-01 00:00:00", "ds_acq_end_time": "2020-12-31 00:00:00", "ds_acq_place": "三江源地区", "ds_acq_lon_east": null, "ds_acq_lat_south": null, "ds_acq_lon_west": null, "ds_acq_lat_north": null, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "open-access", "ds_total_size": 31843144, "ds_files_count": 0, "ds_format": "*.shp", "ds_space_res": "", "ds_time_res": "年", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "e30ec739-e8bb-4c38-8e77-0f7ea124526b.png", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "952adb3f-3ede-4a94-942a-7de772f1bfc5", "ds_serv_man": null, "ds_serv_phone": null, "ds_serv_mail": null, "doi_value": "", "subject_codes": [], "quality_level": 0, "publish_time": "2026-08-26 10:44:03", "last_updated": "2026-08-26 10:44:03", "protected": false, "protected_to": null, "lang": "zh", "cstr": null, "i18n": { "en": { "title": "A dataset of boundary and length of glaciers in the Three–River Headwaters region during 2000–2020", "ds_format": "*.shp", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "
The Three–River Headwaters region is located in the southern part of Qinghai Province, in the heart of the Tibetan Plateau. It is the source of the Yangtze River, the Yellow River and the Lancang River (known as the Mekong River outside China), and is known as the “Water Tower of China”. The glaciers developed in this area are important water sources for many rivers. This study first used Landsat TM/ETM+/OLI/OLI–2 remote sensing images and DEM data, combined with deep learning models, to achieve the preliminary automatic extraction of glacier boundaries in the Three–River Headwaters region at different periods (2000, 2005, 2010, 2015 and 2020). Then, manual visual interpretation was used to check and revise each glacier boundary, and the Randolph Glacier Inventory 7.0 glacier inventory data and the second glacier inventory data of China were referred to for the improvement of relevant attribute information, obtaining the multi–period glacier boundary dataset of this region. Finally, the glacier centerline method was used to extract the multi-period glacier length data of this region. The dataset contains two files: (1) the glacier inventory data in the Three–River Headwaters region; (2) the glacier length data in the Three–River Headwaters region. This dataset can be used as the basic data for studies on glacier change in the Three–River Headwaters region and the response of glaciers to climate change.", "ds_time_res": "years", "ds_acq_place": "sanjiangyuan area", "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, "allow_update_data": false, "ds_topic_tags": [ "冰川", "冰川长度", "Landsat影像", "深度学习", "三江源" ], "ds_subject_tags": [], "ds_class_tags": [], "ds_locus_tags": [ "三江源地区" ], "ds_time_tags": [ 2005, 2010, 2015, 2020 ], "ds_contributors": [ { "true_name": "张聪", "email": "zc1549350717@163.com", "work_for": "喀什大学 生命与地理科学学院", "country": "中国" }, { "true_name": "赵嘉威", "email": "2023222966@nwnu.edu.cn", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" }, { "true_name": "柴春梅", "email": "ccm_0211@126.com", "work_for": "喀什大学 生命与地理科学学院", "country": "中国" }, { "true_name": "何浩天", "email": "13699390760@163.com", "work_for": "喀什大学 生命与地理科学学院", "country": "中国" }, { "true_name": "孙美平", "email": "sunmeiping1982@163.com", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" }, { "true_name": "姚晓军", "email": "xj_yao@nwnu.edu.cn", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "张聪", "email": "zc1549350717@163.com", "work_for": "喀什大学 生命与地理科学学院", "country": "中国" }, { "true_name": "赵嘉威", "email": "2023222966@nwnu.edu.cn", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" }, { "true_name": "柴春梅", "email": "ccm_0211@126.com", "work_for": "喀什大学 生命与地理科学学院", "country": "中国" }, { "true_name": "何浩天", "email": "13699390760@163.com", "work_for": "喀什大学 生命与地理科学学院", "country": "中国" }, { "true_name": "孙美平", "email": "sunmeiping1982@163.com", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" }, { "true_name": "姚晓军", "email": "xj_yao@nwnu.edu.cn", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" } ], "ds_managers": [ { "true_name": "姚晓军", "email": "xj_yao@nwnu.edu.cn", "work_for": "西北师范大学地理与环境科学学院", "country": "中国" } ], "category": "冰川" }
