摘要
以云南省烤烟主产烟区2003~2007年烤烟C3F为研究对象,利用地统计学与GIS技术结合的方法研究了云南省烤烟主产烟区钾含量的空间分布特征和年度变化情况。结果表明:云南省各年度烤烟钾含量偏低,其空间分布特征差异明显;2003年至2005年烤烟钾含量明显升高,2005年至2007年有缓慢下降的趋势;思茅地区烤烟钾含量较高,年度间保持较稳定,其它地区烤烟钾含量较低,年度间变幅较大。
Spatio-temporal variability of potassium content in C3F flue-cure tobacco leaves from main growing areas in Yunnan province between 2003 and 2007 was studied by geostatistics and GIS technique.Results indicated that potassium content in flue-cure tobacco leaves in Yunnan province was low,and the spatial variability was significantly different.Potassium content greatly increased from 2003 to 2005 and slowly decreased from 2005 to 2007.Potassium content was higher and stable in Simao area,while lower and changed greatly between years in other areas.
