摘　　要：为掌握江苏省太仓市耕地土壤基本属性,于2021年秋季采集区域内88个土壤样品,样品经制备、实验室检测后,获取土壤有机质(SOM)、全氮(TN)、全磷(TP)、全钾(TK)、酸碱度(pH)5项属性值。基于ArcGIS软件地统计分析模块中的普通克里格插值功能,得到土壤属性的空间分布特征。结果显示,太仓市SOM、TN、TP和TK分别为25.26、1.48、1.45和10.53 g/kg。在空间分布上,SOM和TN具有一定的相似性,整体上呈“西高东低”的趋势;TP和TK分别为“北高南低”和“东高西低”。太仓市pH均值为7.51,呈中性偏弱碱性。In order to understand the basic soil properties of cultivated land in Taicang City,Jiangsu Province,this study collected 88 soil samples in the autumn of 2021.After preparation and laboratory testing,five attribute values of soil organic matter(SOM),total nitrogen(TN),total phosphorus(TP),total potassium(TK),and pH were obtained.Based on the ordinary Kriging interpolation function in the statistical analysis module of ArcGIS software,the spatial distribution characteristics of soil attributes were obtained.The results showed that the SOM,TN,TP,and TK in Taicang City were 25.26,1.48,1.45 and 10.53 g/kg,respectively.In terms of spatial distribution,SOM and TN have certain similarities,showing an overall trend of“high in the west and low in the east”;TP and TK are“high in the north and low in the south”and“high in the east and low in the west”,respectively.The average pH value in Taicang City is 7.51,which is neutral to slightly alkaline.
