摘　　要：立足于国产谷物测产系统的需求,开发谷物产量数据处理和产量分布图生成系统。确立了该系统主要功能和系统层次结构,选用了距离反比加权空间产量数据插值(Inverse Distance to Power)算法,采用值过滤和3σ法则滤除粗大产量数据,研究了等值线产量图生成方法,开发了具有空间数据插值、误差产量数据过滤、产量数据统计分布、原始产量点图、栅格图和等值线图的谷物产量图生成系统。Grain yield map is the important means for analyzing and managing data of yield monitor system. The authors developed a yield mapping system software for the requirement of national grain yield monitoring system. The main function and system layer frame of the yield map software are confirmed by analyzing the crop yield distribution map system in existence. Inverse distance to power algorithm is selected as yield data interpolation method. The method of data filtering and 30 theorem were used to filter the big errors on yield data. The yield mapping sofiwares with spatial data interpolation, error data filtering, yield data statistic distributing, raw yield map, grid yield map and contour yield map functions were developed.
