全国第二次土壤普查农田肥力数据库(1980-1996年)
收藏资源简介:
第二次土壤普查农田肥力数据库数据来源于全国第二次土壤普查办公室、中华人民共和国农业部、中国土壤系统分类相关课题,依据第二次土壤普查数据,以土种为单位,提取了地形地貌、土地利用、土壤主要性状、生产性能和障碍因子,以及耕层土壤养分数据。目的是提供上世纪80年代农田耕层土壤肥力的基础数据,便于土壤质量评价或不同时段土壤肥力的对比。
The Farmland Fertility Database of the Second National Soil Survey is derived from the Second National Soil Survey Office of China, the Ministry of Agriculture of the People's Republic of China, and relevant research projects on Chinese Soil Taxonomy. Based on the data collected in the Second National Soil Survey, this database extracts indicators including topography and geomorphology, land use types, major soil properties, crop production performance, limiting soil factors, and topsoil nutrient data, taking soil series as the statistical unit. The objective of this dataset is to provide foundational data on farmland topsoil fertility from the 1980s, to facilitate soil quality assessment or comparative analysis of soil fertility across different time periods.
