运用GIS技术及地统计学方法，研究了川北植烟土壤有机质和全氮空间变异特征及其影响因素。结果表明，植烟土壤有机质含量变幅为(5.80～42.00)g.kg-1，全氮含量变幅为(0.66～2.39)g.kg-1，土壤有机质和全氮块金系数分别为61.7%和72.0%，说明空间自相关性较弱。空间插值表明，旺苍县绝大部分区域及剑阁县中部土壤有机质含量适宜，而元坝区和剑阁县区域内较大范围边缘有机质较缺乏；剑阁县及元坝区大部分区域土壤全氮含量适宜，而旺苍县大部分区域土壤全氮含量偏高。

Spatial variability of organic matter and total nitrogen in north tobacco-growing areas of Sichuan province were studied by using GIS technology and relevant statistical methods. Results showed that organic matter content in the sampled area was between 5.80~42.00 g.kg-1, and total nitrogen content varied between 0.66~2.39g.kg-1. Half variance analysis showed that the block gold coefficient of oil organic matter and total nitrogen were 61.7%and 72.0%respectively, which showed weak spatial autocorrelation. Spatial interpolation showed that soil organic matter content was appropriate while total nitrogen content was higher above average in most places of Wangcang county. Soil organic matter content was relatively low while total nitrogen content was appropriate in Yuanba county. Soil organic matter content was appropriate in central part of Jiange county while relatively low in surrounding areas. Total nitrogen content was at appropriate level in most places of Jiange.
