绿洲过渡带是塔克拉玛干沙漠生态安全的天然屏障, 同时也是受气候变化影响最为敏感的脆弱地带, 开展绿洲农田生态系统长期定位观测, 对于该区域生态环境建设和经济社会可持续发展具有至关重要的作用。位于塔克拉玛干沙漠南缘的新疆策勒荒漠草地生态系统国家野外科学观测研究站(简称“策勒站”), 自2004年以来坚持开展当地典型农作物收获期性状和产量的长期生态观测。该数据集统计了2005-2010年策勒站农田观测场的生物观测数据, 主要包括样地背景(含作物种类、轮作体系、肥料投入、农药投入和灌溉制度等主要信息)以及作物收获期性状和产量(含株数、株高、铃重、衣分、密度和地上部干重等主要信息)等数据。该数据集可为荒漠植被稳定维持、人沙和谐共处、绿洲农田健康发展的研究提供重要的科学依据, 为干旱区作物选育、耕作制度完善以及作物收获期性状情况提供基础资料。

Oasis transition belt is the natural barrier of ecological security in the Taklimakan Desert, and it is also the most sensitive and vulnerable area affected by climate change. The long-term positioning observation of oasis farmland ecosystem plays a crucial role in the construction of ecological environment and the sustainable development of economy and society in this region. The Cele National Station of Observation and Research for Desert-Grassland Ecosystems of Xinjiang of the Chinese Academy of Sciences (referred as “Cele Station” hereafter), located in the southern edge of the Taklimakan Desert, has been carrying out long-term ecological observation of the characteristics and yields of local typical crops at harvest time since 2004. This dataset collected the biological observation data of Cele Station from 2005 to 2010, which mainly included the plot background (including crop types, rotation system, fertilizer input, pesticide input, and irrigation system) and crop traits and yield (including plant number, plant height, boll mass, lint percentage, density, and aboveground dry mass). The dataset could provide important scientific basis for the research on the stability of desert vegetation, the harmonious coexistence of human-sand relationship, and the healthy development of oasis farmland. It could also provide basic information for crop selection, cultivation system improvement, and crop trait changes during harvesting period in arid areas.
