黄土高原地区农田生态系统土壤主要理化特征（容重、pH、水分）数据集(2011-2017)

本研究针对黄土高原农田典型分布区域，包括黄土塬区宁县、黄土丘陵区庄浪县、关中平原区武功县、银川平原区平罗县、风沙区准格尔旗以及汾河谷地一带，测定了以上典型县域农田土壤容重、pH、颗粒组成，此外，在平罗县、武功县、庄浪县、准格尔旗分别测定了土壤水稳性团聚体含量。土壤水分的获取主要在安塞县、长武县、武功县、庄浪县完成。“黄土高原地区农田生态系统土壤主要理化特征（容重、pH、土壤水分）数据集”。该数据集包括两个数据表，其中第一个数据表（容重、pH、结构组分）有898条记录，第二个数据表（土壤水分）有25100条记录。容重、pH、颗粒组成、水稳性团聚体指标主要采用野外采样及室内测定等方式获取。本数据集开放共享。This study targeted typical farmland distribution regions across the Loess Plateau, including Ning County (Loess Tableland), Zhuanglang County (Loess Hilly Region), Wugong County (Guanzhong Plain Region), Pingluo County (Yinchuan Plain Region), Zhungeer Banner (Sandy Area), and the Fen River Valley area. Soil bulk density, pH, and particle size composition of farmland soils in these typical counties were measured. Additionally, the content of soil water-stable aggregates was determined separately in Pingluo County, Wugong County, Zhuanglang County, and Zhungeer Banner. Soil moisture data were primarily collected in Ansai County, Changwu County, Wugong County, and Zhuanglang County. The dataset is titled *Dataset of Main Physicochemical Properties of Farmland Ecosystem Soils in the Loess Plateau (Bulk Density, pH, Soil Moisture)*. It contains two data tables: the first table (covering bulk density, pH, and particle size composition) has 898 records, while the second table (focusing on soil moisture) has 25,100 records. Indicators including soil bulk density, pH, particle size composition, and soil water-stable aggregate content were mainly obtained via field sampling and laboratory measurements. This dataset is openly shared for academic and research use.
