摘要: 应用地质统计学的方法对北京昌平县南邵乡2640hm2土地上的土壤有机质、全氮、有效氮、有效磷及有效钾的空间分布特征,进行了定量分析,并绘出他们的等值线图。对于研究和评价大比例尺区域土壤养分空间变异规律和动态变化有一定的理论和实践意义。

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 matte,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 nutrient sona large scale.

Key words: Soil nutrients, Spatial variation, Kriging method
