HWSD(Harmonized World Soil Database)是联合国粮食及农业组织(FAO)和国际土壤参考与信息中心(ISRIC)共同开发的世界土壤数据集。该数据集是一份高分辨率(1 km),全球范围的土壤数据库,包括有关土壤类型、土壤属性、土壤质地、土层深度和土壤水分等方面的信息。HWSD数据集是基于大量地面测量和遥感数据,以及土壤分类系统和...
全球30弧秒土壤数据集(Harmonized World Soil Database,HWSD),是国际粮农组织与IIASA、ISRIC世界土壤信息、中国科学院土壤科学研究所(ISSCAS)和欧盟委员会联合研究中心(JRC)合作成果。HWSD是一个30弧秒的栅格数据库,包含超过15000个不同的土壤制图单元,由世界范围内现有的区域和国家土壤信息更新与1:5000 000比例尺的...
Database (HWSD). This state-of-the-art database was achieved in partnership with: • ISRIC-World Soil Information together with FAO, which were responsible for the development of regional soil and terrain databases and the WISE soil profile database; • the European Soil Bureau Network...
We combine WISE soil data with the HWSD to identify representative profiles.We cluster the soils in the HWSD to produce coarser-resolution soil maps.The web-based tool MarkSimGCM now includes downscaled climate data from CMIP5.MarkSimGCM outputs soil profiles for any location for use in ...
hwsdr Programmatic interface to the Harmonized World Soil Database 'HWSD' web services (https://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1247). Allows for easy downloads of 'HWSD' soil data directly to your R workspace or your computer. Routines for both single pixel data downloads and...
Further expansion and update of the HWSD is foreseen for the near future, notably with the excellent databases held in the USA (Natural Resources Conservation Service US General Soil Map, STATSGO), Canada (Agriculture and AgriFood Canada: The National Soil Database NSDB), and Australia (CSIRO,...
Several other global data sets have been built on the foundations of the Soil Map of the World, the Harmonized World Soil Database (HWSD) being the most recent example (FAO/IIASA/ISRIC/ISSCAS/JRC, 2012). The HWSD has been used in a wide range of global modeling studies even thou...
数据来源于联合国粮农组织(FAO)和维也纳国际应用系统研究所(IIASA)所构建的世界土壤数据库(Harmonized World Soil Database version 1.1 )(HWSD). 中国境内数据源为第二次全国土地调查南京土壤所所提供的1:100万土壤数据。 该数据可为建模者提供模型输入参数,农业角度可用来研究生态农业分区,粮食安全和气候变化等。数...
