2000-2008年测定的黄土丘陵区（延安地区）不同利用类型土壤属性，化学指标包括全氮、全磷、有机质、活性有机碳、碱解氮、速效磷、速效钾、CaCO3、pH、CEC；物理指标包括砂粒、物理性粘粒、粘粒、微团聚体、微团聚体平均重量直径（MICMWD）、结构系数、水稳性团聚体、团聚体平均重量直径（MWD）、总孔度、毛管孔度、容重、渗透系数（K10）、抗冲性；生物指标包括微生物碳和氮、磷酸酶、蔗糖酶、脲酶、呼吸强度。
Soil properties under different land use types in the Loess Hilly Region (Yan'an area) measured from 2000 to 2008. Chemical indicators include total nitrogen, total phosphorus, organic matter, labile organic carbon, alkaline hydrolyzable nitrogen, available phosphorus, available potassium, CaCO3, pH, and cation exchange capacity (CEC). Physical indicators include sand particles, physical clay particles, clay particles, micro-aggregates, mean weight diameter of micro-aggregates (MICMWD), structural coefficient, water-stable aggregates, mean weight diameter of aggregates (MWD), total porosity, capillary porosity, bulk density, infiltration coefficient (K10), and anti-scourability. Biological indicators include microbial biomass carbon and nitrogen, phosphatase, sucrase, urease, and respiration intensity.
