| 摘 要： | 以庆安县南部1993、2000和2003年监测的土壤有机质、全氮、全磷、速效钾含量为数据源，利用SPSS和GIS软件对庆安县南部土壤养分的数量变化和空间变化进行分析。结果表明：庆安县南部土壤各种养分含量具逐年下降的趋势，空间变异强度为中等，土壤养分的空间分布状态呈现由西北向东南逐渐减少的趋势。

| Abstract: | Taking the soil organic matter,total nitrogen,phosphorus,potassium content detected in 1993,2000 and 2003 as data resources,this study aimed to analyze the quantity and space-time variation of soil nutrients in south Qingan county by SPSS and GIS software.The results showed that the soil nutrients content have been decreasing year by year,the spatial variation also declined from strong to medium and the spatial distribution of soil nutrients demonstrated a downtrend form the northwest to the southeast in south Qingan county. |
