2004-2015年海伦站不同管理方式下黑土农田土壤含水量长期监测数据集

土壤水是农田生态系统中物质运移的载体，对作物生长和生态系统功能有重要影响。研究表明，水分是我国东北黑土区农业生产的主要限制因素。土壤含水量是中国生态系统研究网络（CERN）陆地生态系统水环境观测的重要指标。中国科学院海伦农业生态实验站（简称海伦站）是我国唯一从事黑土农田生态系统长期定位监测、研究与示范的国家级野外台站。1993年，海伦站将典型作物种植制度和施肥制度相结合建立黑土农田土壤水分观测场，按照CERN的要求进行长期水分数据观测及汇交工作。本数据集收集、整理了2004–2015年典型农田管理方式下土壤剖面含水量长期观测数据，为研究东北黑土区水资源变化和农业可持续发展提供基础数据支撑。

Soil water acts as a carrier for material transport in farmland ecosystems, and exerts a significant impact on crop growth and ecosystem functions. Studies have shown that soil moisture is the primary limiting factor for agricultural production in the black soil region of Northeast China. Soil moisture content is a key indicator for aquatic environment observation of terrestrial ecosystems under the Chinese Ecosystem Research Network (CERN). The Hailun Agro-ecological Experimental Station of the Chinese Academy of Sciences (referred to as Hailun Station) is the only national-level field station in China dedicated to long-term in-situ monitoring, research and demonstration of black soil farmland ecosystems. In 1993, Hailun Station established soil moisture observation plots in black soil farmlands by combining typical crop cropping systems and fertilization regimes, and conducted long-term observation and submission of moisture data in compliance with the requirements of CERN. This dataset collects and organizes long-term observation data of soil profile moisture content under typical farmland management practices from 2004 to 2015, providing basic data support for research on water resource changes and agricultural sustainable development in the black soil region of Northeast China.
