| 摘 要： | 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。

Analysis of Soil Nutrient Content and Its Spatial and Temporal Characteristics in Hills and Plains Intersection Zone |
| |
| Abstract: | Anlu City is located in the intersection zone among the hilly branches of Tongbai Mountain , Dahong Mountain and Jianghan Plain. According to the Ministry of Agriculture project of formula fertilization by soil testing , spatial distribution and variability of soil OM , nitrogen , phosphorus , potassium and other nutrients in the content level were analyzed.At the same time , the content of each nutrient area distribution which obtained by Kriging interpolation were compared with the second soil survey datas in order to understand the time variation characteristics of soil nutrient content. |
