基于站点观测的中国1km土壤湿度日尺度数据集(2000-2022)
本研究提供了中国范围1km高质量的土壤湿度数据集-SMCI1.0(Soil Moisture of China by in situ data, version 1.0),SMCI1.0是包含2000-2022年、日尺度、以10厘米为间隔10层深度(10-100cm)的高时空分辨率土壤湿度,数据单位为0.001m³/m³,缺失值为-999,投影为WGS1984。该数据集是以中国气象局提供的1,648个站点观测10层土壤湿度作为基准,使用ERA5_Land气象强迫数据、叶面积指数(LAI)、土地覆盖类型(Landtypes)、地形(DEM)和土壤特性(Soil properties)作为协变量,通过机器学习方式获得。本研究进行了两组实验以验证SMCI1.0的精度,时间尺度上:ubRMSE为0.041-0.052,R为0.883-0.919;空间尺度上:ubRMSE为0.045-0.051,R为0.866-0.893。 由于SMCI1.0是基于实地观测的土壤湿度,它可以作为现有基于模型和卫星数据集的有效补充。该数据产品可用于各种水文、气象、生态分析和建模,尤其在需要高质量、高分辨率土壤湿度的应用上至关重要。有关数据集的引用及详细描述,请阅读说明文档。为便于使用,本研究提供了两种不同分辨率的版本:30 秒(~1km)和0.1度(~9km)。

全国 1∶200 000 数字地质图(公开版)空间数据库
As the only one of its kind, China National Digital Geological Map (Public Version at 1∶200 000 scale) Spatial Database (CNDGM-PVSD) is based on China' s former nationwide measured results of regional geological survey at 1∶200 000 scale, and is also one of the nationwide basic geosciences spatial databases jointly accomplished by multiple organizations of China. Spatially, it embraces 1 163 geological map-sheets (at scale 1: 200 000) in both formats of MapGIS and ArcGIS, covering 72% of China's whole territory with a total data volume of 90 GB. Its main sources is from 1∶200 000 regional geological survey reports, geological maps, and mineral resources maps with an original time span from mid-1950s to early 1990s. Approved by the State's related agencies, it meets all the related technical qualification requirements and standards issued by China Geological Survey in data integrity, logic consistency, location acc racy, attribution fineness, and collation precision, and is hence of excellent and reliable quality. The CNDGM-PVSD is an important component of China' s national spatial database categories, serving as a spatial digital platform for the information construction of the State's national economy, and providing informationbackbones to the national and provincial economic planning, geohazard monitoring, geological survey, mineral resources exploration as well as macro decision-making.
