2003-2007年西藏拉萨站农田土壤水分物理性质监测数据

本数据产品是在《中国生态系统定位观测与研究数据集》丛书的《农田生态系统卷》之西藏拉萨站1册的基础上进行数字化加工，通过完善元数据并与实体数据相关联，生产了本数据产品。本数据产品包含了西藏拉萨站按照CERN长期监测指标体系和规范开展的西藏拉萨农田生态系统土壤含水量、农田灌溉量、雨水水质、水面蒸发量、农田蒸散量、土壤水分常数的监测数据。数据范围自2003年至2007年。土壤的保水供水能力和对作物生长是极为重要的，同时根据特定年限的土壤水分特性采取一些农艺措施调节耕层排水抗涝能力也是十分必要的，掌握它们的变化规律对于农田水分管理有重要的意义。本数据产品同时包含拉萨站观测点介绍及观测指标获取方法与过程的关联文档。

This data product was developed via digitized processing based on Volume 1: Lhasa Station, Tibet of the *Agricultural Ecosystem Volume* within the *China Ecosystem Station-based Observation and Research Dataset Series*, by optimizing metadata and associating it with physical entity data. It contains monitoring data of soil moisture content, farmland irrigation volume, rainwater quality, surface evaporation, farmland evapotranspiration, and soil moisture constants for the Lhasa agricultural ecosystem in Tibet, collected by Lhasa Station in accordance with the long-term monitoring indicator system and specifications of the Chinese Ecosystem Research Network (CERN). The dataset spans the period from 2003 to 2007. Soil water retention and supply capacity are critically important for crop growth. Moreover, it is necessary to implement agronomic measures tailored to the soil moisture characteristics of specific years to regulate the drainage and flood resistance of the plow layer. Understanding the variation patterns of these parameters holds significant value for farmland water management. This data product also includes supporting documents that introduce the observation stations at Lhasa Station and detail the methods and procedures for acquiring each observation indicator.
