安陆市位于桐柏山、大洪山两余脉蔓延的丘陵与江汉平原交会地带,结合农业部测土配方施肥项目,重点分析耕地土壤有机质(OM)、氮、磷、钾等养分各含量级别的空间分布及变异。同时,将通过Kriging插值而得到的各养分含量面积分布与第二次土壤普查资料进行比较分析,以了解土壤养分含量的时间变化特征。
Anlu City, located in Tongbai Mountain, Dahong Mountain, two veins of the spread of the hills and the Jianghan Plain intersection zone, combined with the Ministry of Agriculture soil testing and fertilization project, focusing on analysis of soil organic matter (OM), nitrogen, phosphorus, potassium and other nutrient content levels Spatial distribution and variation. At the same time, the distribution of each nutrient content obtained by Kriging interpolation is compared with the second soil census data to understand the temporal variation characteristics of soil nutrient content.
