Study on the Spatial Distribution Characteristics of Basic Properties of Cultivated Soil in Taicang City
In order to understand the basic soil properties of cultivated land in Taicang City,Jiangsu Province,this study collected88 soil sam-ples in the autumn of 2021. After preparation and laboratory testing,five attribute values of soil organic matter (SOM),total nitrogen (TN),to-tal phosphorus (TP),total potassium (TK),and pH were obtained. Based on the ordinary Kriging interpolation function in the statistical analy-sis 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 similari-ties,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.
