摘　　要：简单介绍了新型的多媒体地图测绘系统(VMS系统),并运用该系统建立了试验田电子边界地图,采集小麦长势图像。为此,采用地统计学对镇江市丹徒区一块试验田的土壤养分、小麦产量的空间变异性及相关性进行了研究,生成了碱解氮、速效磷、速效钾含量和小麦产量的空间分布图,并结合小麦的长势图像对这些分布图做了定性分析。In the paper a new kind of Video Mapper System was introduced in detail, called VMS, managed to collect boundary map of the field and images of wheat. Spatial distributions and relationship between available nitrogen, phosphorus, analysis potassium and wheat yield in the Dantu area of Zhenjiang were analyzed using geostatistics and partial correlation methods. The images of wheat were combined with these spatial distribution maps to research briefly in the paper
