黑龙江土种数据库构建——基于第二次土壤普查数据

Construction of Heilongjiang soil species database-based on the second national soil survey

本数据库是在全国第二次土壤普查黑龙江土种志,黑龙江土壤,中国土壤,中国土种志等数据和资料的基础上,根据E-R数据模型的理论构建的关系型数据库,实现了数据库存贮和查询等功能。数据库包含黑龙江省63个市县,17个土类,48个亚类,127个土属和254个土种的数据资源,描述了土种的分布、面积、属性及生产性能,以及每个土种的典型剖面。该数据库可为黑土区域土壤肥力评价、土壤质量评价以及土壤资源可持续利用提供数据支持。
