平陆烟区烤烟砷含量的空间分布特征
Spatial Distribution Characteristics of Arsenic Content in Flue-cured Tobacco Leaf in Tobacco Planted Area of Pinglu County
摘要
Abstract
In order to explore the arsenic (As) distribution of tobacco in the major tobacco production areas in Pinglu county,Shanxi province,68 flue-cured tobacco samples (C3F)were collected from this place in 2012 as materials,the As concentration was measured,and the spatial distribution of As content was studied by geostatistics and GIS technique.The mean concentration of As was 0·353 mg/kg.The concentration of As first increased and then declined slowly from west to east and from north to south.The best theoretical model for the As content in tobacco leaf was Exponential model,and the anisotropy index was greater than 1,showing anisotropic.The spatial difference of the spot size and shape of the As content in flue-cured tobacco leaf was obvious,the spatial correlation was great,and the trend effect was obvious.The areas with higher As content were mainly distributed in northern Caochuan town,center of Podi country and Shengrenjian town,western Sanmen town,southwestern Zhangdian town,northeastern Duma country.关键词
