多年冻土退化会削弱地基稳定性、加剧物质迁移与热融灾害，威胁工程基础设施安全，推高维护成本、缩短服役年限，带来显著经济损失。本数据集来源于 2022 年发表于《Communications Earth & Environment》（DOI:10.1038/s43247-022-00568-6）的青藏高原多年冻土退化经济损害研究成果，包含1km 空间分辨率的青藏高原未来多年冻土危险等级栅格数据，以及论文图 2、图 3、图 4 对应的原始统计数据。", "ds_source": "", "ds_process_way": "", "ds_quality": "", "ds_acq_start_time": "2008-01-01 00:00:00", "ds_acq_end_time": "2090-12-31 00:00:00", "ds_acq_place": "第三极,青藏高原", "ds_acq_lon_east": 104.0, "ds_acq_lat_south": 26.0, "ds_acq_lon_west": 73.0, "ds_acq_lat_north": 39.0, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "open-access", "ds_total_size": 2776951, "ds_files_count": 0, "ds_format": "*.shp，*.xlsx", "ds_space_res": "1km", "ds_time_res": "", "ds_coordinate": "WGS84", "ds_projection": "Albers", "ds_thumbnail": "fa190acc-e73c-46f3-8e6a-79fb1f0ccddc.png", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "52b7b79b-860c-49a5-9083-9a70cf8bed5a", "ds_serv_man": "李红星", "ds_serv_phone": "0931-4967592", "ds_serv_mail": "ncdc@lzb.ac.cn", "doi_value": "", "subject_codes": [ "170.4510" ], "quality_level": 0, "publish_time": "2026-05-08 18:26:46", "last_updated": "2026-05-08 18:26:50", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.ncdc.permafrost.db7315.2026", "i18n": { "en": { "title": "Dataset for Predicting the Risk of Future Permafrost Degradation in the Qinghai Tibet Plateau", "ds_format": "*.shp，*.xlsx", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "
The degradation of permafrost over the years will weaken the stability of the foundation, exacerbate material migration and thermal melting disasters, threaten the safety of engineering infrastructure, increase maintenance costs, shorten service life, and bring significant economic losses. This dataset is derived from the research results on economic damage caused by permafrost degradation in the Qinghai Tibet Plateau, published in Communications Earth & Environment in 2022 (DOI: 10.1038/s43247-022-00568-6).
