为了探究土壤有机质含量及空间分布进而实行分区施肥，本研究以安徽省合肥市长丰县的草莓产业为例，利用长丰县的测土配方项目收集了1 986个土壤采样点位的有机质数据，借助普通克里格（OK）、随机森林（RF）、随机森林残差克里格（RFRK）3种预测模型，结合与土壤形成相关的地形、植被等6个环境协变量，对研究区的土壤有机质空间分布进行预测，绘制空间分布图，并依据有机质含量划分施肥分区，针对各个分区提出不同的草莓施肥方案。结果表明，3种模型所预测的土壤有机质总体分布趋势基本一致，呈现北高南低的特点，有机质总体含量为8~30 g·kg-1。根据土壤有机质的丰缺程度，将有机质含量为15~25 g·kg-1的地区划定为中等施肥区，建议施用农家肥 45.0~52.5 t·hm-2；有机质含量高于 25 g·kg...
