摘　　要：以北海市内52个逐日雨量站点资料为基础,统计了区域主汛期月降水量时空分布特征;并以各站点月平均降水量为输入,利用ArcGIS克里金插值法对其空间分布特征展开分析。结果表明,ArcGIS的克里金插值法能在一定程度上反映北海市降水量的空间分布情况,北海市降雨量月际变化较大,空间分布不均,月平均降水量基本由东向西增加,向西降水较为丰沛,可能是受北海地区西部暖湿气流、地理位置、地势构造等因素影响所致。Based on the data of 52 daily rainfall stations in Beihai City,the spatiotemporal distribution characteris⁃tics of regional monthly precipitation during the main flood season were statistically counted.With the monthly aver⁃age precipitation of various rainfall stations as input,the spatial distribution characteristics was analyzed by ArcGIS Kriging interpolation method.The results of analysis demonstrate ArcGIS Kriging interpolation method can reflect to certain extent the spatial distribution of precipitation in Beihai city.The monthly variation of rainfall in Beihai City is significant,with uneven spatial distribution.The average monthly precipitation generally increases from east to west.The precipitation in the west is relatively abundant,which may be caused by factors such as the warm and humid airflow in the western part of Beihai region,geographical location,and terrain structure.
