| Abstract: | The town of Nanshao,Changping county in Beijing has 264 hectares of land.One hundred and six soil samples were collected and analyzed for soil organic matter,total N,available N,available P and available K in 1993.The spatial variation of these soil properties was quantitatively analyzed by geostatistical methods.The contour of these soil characteristics was also drawn by Kriging method.The geostatistical method showed some importance in studying and estimating the spatial variation and changes of soil nutrients on a large scale. |
