摘　　要：CERN农田站生物长期样地背景和耕作制度本底数据集是CERN农田生态系统的台站在长期样地建立之初的样地和种植制度本底数据的综合集成,包含15个农田站、5个荒漠农田复合站和1个沼泽农田复合站共21个生态站148个长期样地的本底信息、代表性农田类型和耕作制度的观测记录。数据集包含生态站代码、生态站名称、样地代码、样地名称、样地类别、样地代表性、地理位置、行政位置、海拔高度、样地面积及形状、样地建立时间和设计使用年数、作物名称与轮作体系、耕作制度、灌溉制度等字段。该数据集可以为作物资源分布和农业区划等方面的研究提供基础数据支持。This dataset is a comprehensive integration of the background data of plots and cropping systems from CERN farmland ecosystems stations at the beginning of the establishment of long-term plots.It involves the background information,observation records of representative farmland types and farming systems of 148 long-term plots from 21 ecological stations,including 15 agricultural stations,5 desert-agriculture composite stations and one wetland-agriculture composite station.The dataset covers various fields,such as station code,station name,plot code,plot name,plot type,plot representativeness,geographical location,administrative location,altitude,plot area and shape,plot establishment time and design service life,crop name and rotation system,farming system and irrigation system.The dataset can provide basic data support for the research on crop resource distribution,farming system zoning,etc.
