本数据集收录1123条物种出现记录，均为全球生物多样性信息设施（GBIF, Global Biodiversity Information Facility）中匹配下述组合查询条件的有效条目：需同时满足无地理空间问题（HasGeospatialIssue）为false、存在有效坐标（HasCoordinate）为true、出现状态为存在（OccurrenceStatus为Present）、记录依据类型（BasisOfRecord）不属于化石（Fossil）与活标本（Living Specimen）范畴、分类单元键（TaxonKey）对应裸穗豚草（Ambrosia psilostachya DC.），且记录年份介于1970年至2000年（含首尾）；此外需额外满足两项筛选规则：其一为建立方式（EstablishmentMeans）不属于栽培（MANAGED）与引入（INTRODUCED）类型，或建立方式字段为空；其二为坐标不确定性米数（CoordinateUncertaintyInMeters）小于1000米，或该字段为空。本数据集包含来自157个组成数据集的1123条完整记录，详细信息请参阅：https://api.gbif.org/v1/occurrence/download/0017572-250402121839773/datasets/export。需注意，本次下载所包含的部分独立数据集，其授权条款可能更为宽松。
