| 摘 要： | 运用GIS和地统计学相结合的方法研究了1982年和2002年河南省郏县烟区土壤有机质、全氮、全磷、全钾的时空变异。结果表明,20年间土壤有机质、全氮含量有所降低,特别是有机质下降较多,全磷和全钾基本持平;从空间上看,这4种养分指标朝均一化方向发展。这些变化主要是植烟区管理及施肥等人为因素造成的。 |

| Abstract: | The spatio-temporal variability of soil nutrients,including organic matter,total N,total P and total K,in tobacco growing areas of Jiaxian county of Henan province was investigated from 1982 to 2002 by Geographical information system(GIS) and Geostatisties.The results showed that the average content of organic matter and total N decreased,more for organic matter.Total P and Total K were kept stable.Based on the special variability,the distribution of four soil nutrients trend to be uniformed,which may be due to the fertilizer application and artificial management in tobacco field. |
| Keywords: | GIS Geostatistics Soil nutrients Spatio-temporal variability Tobacco growing areas |
