摘要:

种植业是西藏高原社会经济发展的基础, 受自然条件限制, 主要分布在“一江两河” (雅鲁藏布江、年楚河、拉萨河)等高原河谷区域, 以种植喜凉的青稞(Hordeum vulgare var. coeleste)、小麦(Triticum aestivum)和油菜(芸薹, Brassica rapa var. oleifera)等粮油作物为主。西藏拉萨农田生态系统国家野外科学观测研究站(拉萨站)地处青藏高原腹地的拉萨河谷农业区, 是高原农区种植业的典型代表。以高原农田生态系统的长期动态变化为监测目标, 拉萨站设立了综合观测场、长期试验观测场和农户调查点, 对青稞、小麦和油菜等该区域主要作物的典型种植模式开展长期定位观测。该数据集是2016-2020年拉萨河谷3种主要作物收获期性状和产量观测数据, 包括5个部分: 农田复种指数与作物轮作体系、农田作物主要肥料投入情况、农田灌溉情况、作物收获期性状数据和作物测产数据。该数据集将为高原河谷农区作物生产能力评估、农业可持续生产管理、智慧农业系统构建等方面提供科学依据与数据支撑。

Abstract:

Agriculture is the foundation of social-economic development on the Xizang Plateau. Constrained by the region’s natural conditions, agriculture activities are predominantly concentrated in plateau river valley areas, including the Yarlung Zangbo River, Nyangchu River and Lhasa River. The primary crops cultivated in these areas are grain and oil crops, include highland barley (Hordeum vulgare var. coeleste), wheat (Triticum aestivum) and rapeseed (Brassica rapa var. oleifera), which favor cool climate. The Lhasa National Field Scientific Observation and Research Station of Agro-ecosystem, Xizang (Lhasa Station), is located in the Lhasa River Valley agricultural area in the heart of the Qingzang Plateau, serving as a typical representative site of plateau agricultural regions. With a focus on monitoring the long-term dynamic of the plateau farmland ecosystem, Lhasa Station has established one comprehensive observation field, one long-term experimental observation field and two farmer survey points to conduct long-term and fixed-site observations on typical cultivation patterns of the region’s main crops, including highland barley, wheat, and rapeseed. This dataset includes the observation data of the crop harvest traits and yield in Lhasa River valley collected by Lhasa Station from 2016 to 2020, including five parts: farmland multiple cropping index and crop rotation system, fertilizer input of farmland crops, farmland irrigation, crop harvest trait data, and crop yield data. This dataset will provide scientific basis and data support for agricultural capacity assessment, sustainable agricultural production management and smart agricultural system development in this agricultural area.
