摘要
以黎明镇境内34 km2的范围为研究区,以1 161个表层土壤样本K,N,P元素含量为研究对象,以1∶2 000航摄影像为基础地理信息数据,利用地统计方法分析研究区内表层土壤养分元素的空间分布特征,并针对分析结果为研究区制作变量处方图。在"天地图·黑土地"平台实现空间插值图、变量处方图的在线展示,有利于提高农业生产效率和耕地的单位面积产量。
In order to research the spatial distribution of soil nutrients, 1 161 surface soil samples of Liming Town were collected. All samples were analyzed including K, N, P based on geostatistics, used 1 ： 2 000 aerial image as GIS data base, produced variable rate fertilization map. The TIANDITU system showed the spatial interpolation map and the variable rate fertilization map for users. The study help to improve the efficiency of agricultural production and the yield per hectare.
