摘要: 为研究东阿县土壤养分的空间变异特征,利用SPSS 23对1799个合理布点的土样养分数据进行描述性统计分析,通过ArcGIS 10.2利用普通Kriging方法生成养分插值图。结果表明:研究区域有机质、碱解氮、有效磷、速效钾平均含量分别为15.60 g/kg、91.4 mg/kg、24.12 mg/kg、190 mg/kg。土壤各养分含量均表现出中部地区含量较高,东北部含量次之,西南部最低的变化趋势。土壤质地是影响各养分空间分布的主要因素,成土过程中的沉积分选作用造成各养分沿垂直于黄河岸的方向变程最短。

Abstract: To explore the spatial variability characteristics of soil nutrients in Donge County, the authors descriptively and statistically analyzed 1799 reasonable soil samples by SPSS 23. The ordinary Kriging method in ArcGIS 10.2 was used to form the soil nutrients interpolation map. The results showed that the average contents of soil organic matter, available nitrogen, available phosphorus and available potassium was 15.60 g/kg, 91.4 mg/kg, 24.12 mg/kg and 190 mg/kg, respectively. The contents of each soil nutrient were higher in the central region, then were the northeast and the lowest were in the southwest. Soil texture was the main factor of nutrient spatial distribution, the sedimentary sorting effect in soil-forming process made the range shortest perpendicular to the bank of Yellow River.
