ISRIC Soil Information System (ISIS)

ISRIC Soil Information System (ISIS) brings the ISRIC Soil Reference Collection on-line and characterizes a collection of monoliths with morphological, analytical data that represent the main soil reference groups of the World Reference Base for Soil Resources (WRB). ISIS holds data on the World Soil Reference Collection including over 950 monoliths from over 70 countries with detailed soil profile and environmental data. Users currently have access to site data (60 attributes on location, geology, landform, soil surface properties, hydrology, land-use, vegetation and climate) and soil data (soil profile description according to the FAO Guidelines; 100 physical, chemical and mineralogical attributes; and attributes for classification in the FAO-Unesco Legend (1974), the Revised FAO-Unesco Legend (1988), World Reference Base for Soil Resources (2006), USDA Soil Taxonomy, and a national classification system, as available). ISRIC will continue to enlarge its soil reference.

国际土壤参考与信息中心（International Soil Reference and Information Centre, ISRIC）土壤信息系统（ISIS）将ISRIC土壤参考馆藏上线，并对一批代表世界土壤资源参比基础（World Reference Base for Soil Resources, WRB）主要土壤参比类群的整段土柱标本进行了特征表征。ISIS收录了世界土壤参考馆藏的相关数据，涵盖来自70余个国家的950余件整段土柱标本，附带详细的土壤剖面与环境数据。当前用户可获取两类数据：一是场地数据，包含60项属性，涵盖位置、地质、地貌、土壤表层特性、水文、土地利用、植被与气候等维度；二是土壤数据，包括依据联合国粮食及农业组织（Food and Agriculture Organization of the United Nations, FAO）指南编制的土壤剖面描述、100余项物理、化学与矿物学属性，以及可用于分类的多套分类体系属性，具体包括FAO-联合国教科文组织土壤图例（1974版）、修订版FAO-联合国教科文组织土壤图例（1988版）、世界土壤资源参比基础（2006版）、美国农业部（United States Department of Agriculture, USDA）土壤分类系统，以及可用的国家级土壤分类系统。ISRIC将持续扩充其土壤参考馆藏。
