摘要: 采用传统统计学方法以及地统计学方法结合GIS技术研究了云南省保山市烟区植烟土壤耕层(0~20 cm)pH的时空变异特征。结果表明,2011年保山市烟区植烟土壤pH分布在5.5~6.5的样本占38.3%,2016年下降至32.0%;土壤pH属中等变异强度;2011年和2016年烟区土壤pH块金值/基台值分别为40.9%和25.3%,变程分别为41.5 km与47.2 km,具有中等强度的空间相关性;Kriging最优内插法结果表明,保山市烟区植烟土壤pH呈现逐年下降的趋势,下降趋势由西北方向与东南方向逐渐向中部地区减小,中部地区所受影响不大。

Abstract: The temporal and spatial variability of the soil pH value in Baoshan tobacco-growing areas of Yunnan province was studied by using the traditional statistical methods and the geostatistics method combined with GIS technology. The results showed that the pH value distribution in the sample of 5.5 to 6.5 of the tobacco planted in the tobacco-growing area in 2011 was 38.3% and decreased to 32.0% in 2016. The pH variation belonged to medium variation. The nugget/sill values of soil pH were 40.9% and 25.3%,and the range was 41.5 km and 47.2 km respectively in 2011 and 2016. The spatial correlation was moderate. The Kriging optimal interpolation method showed that the soil pH decreased with the increase of the year,and gradually moved closer to the central area from the northwest and the southeast,the central area was not affected much.

Key words: planted tobacco soil pH, temporal and spatial variability, geostatistics, GIS
