基于地统计的土壤有效磷空间变异分析——以广东乳源县乳城镇为例

Spatial variability aanlysis of soil available phosphorus based on geostatistics——A case study of Rucheng town of Ruyuan country in Guangdong Province

在借鉴国内外学者研究成果的基础上，利用地统计学方法对乳城镇采集的土壤样品数据进行土壤有效磷的空间变异分析。结果表明：研究区的土壤有效磷在空间分布上西部含量高于东部。土壤有效磷含量20～40mg/kg分布面积最广，约占总面积的69%。在此基础上，提出合理施用磷肥的建议。

The paper analyzed the spatial distribution of the soil available phosphorus content in Rucheng by soil sampling and geostatistics, based on research achievements of domestic and foreign scholars. The result showed that the west in the spatial distribution of the available phosphorus content is higher than the east and the area from 20 to 40 mg·kg-1 is the most widely distributed, accounted for about 69%of the total area. On this basis, this paper put forward suggestions for the reasonable use of phosphate fertilizer.
