摘　　要：以太谷县境内的一块冬小麦田为试验区,用手持GPS接收机,按50m×50m的网格定位采样,共采63个采样点,利用实验室化学分析的方法测量各个采样点的养分值,用ArcView3.3中提供的空间分析模块绘制土壤养分的空间分布图,通过分析其分布规律,可为农田精细施肥管理提供科学的依据。63 sample points of soil nutrient,oriented by GPS receiver were collected on a 50 m grid in the field of a winter wheat in Taigu. Soil nutrient data of each sample point was measured by chemical method. Spatial distribution maps of soil nutrient were drawn and analyzed by using spatial analyst model of ArcView3.3 software. The analysis results would provide reference for precise fertilization management.
