This data is the research data used in the paper "Adaptive Cross-Domain Knowledge-Guided Modeling of Urban Population Potential Peak Point Attenuation Laws".Due to confidentiality and privacy considerations, the publicly available data have been de-identified.Data collected on 10 December 2019 were used for model development, while data from 11–13 December 2019 were used for validation. The dataset contained four fields: date, origin grid ID, destination grid ID, and number of flows. The data were organized into square grids with a spatial resolution of 250 m × 250 m, totaling 13,176 grids within the study area. The OD flow dataset on 10 December 2019 contained 71,287 records.本数据集为论文《自适应跨域知识引导的城市人口势能峰值点衰减规律建模》（Adaptive Cross-Domain Knowledge-Guided Modeling of Urban Population Potential Peak Point Attenuation Laws）所使用的研究数据。出于保密与隐私保护考量，公开数据集已完成去标识化处理。2019年12月10日采集的数据用于模型开发，2019年12月11日至13日采集的数据用于模型验证。本数据集包含四个字段：日期、起点网格ID（origin grid ID）、终点网格ID（destination grid ID）以及流量数（number of flows）。数据以空间分辨率为250 m × 250 m的正方形网格进行组织，研究区域内总计包含13176个网格。2019年12月10日的起讫点流量数据集共包含71287条记录。
