GIS支持下的马龙县植烟土壤有效态微量元素评价
GIS-based evaluation of available microelements in tobacco soil in Malong County
摘要
Abstract
144 tobacco soil samples were collected in Malong county. Descriptive analysis characteristics and spatial variation characteristics were studied, and spatial distribution maps of available microelements in soil were made with ordinary Kriging interpolation method. Results indicated that anisotropic structure of available microelements in tobacco soil varied and the spatial variability of 7 available microelements were caused by structural factors and random factors. Spatial distribution maps showed that available B was widely deficient in tobacco soil of Malong county, while available Cu, Fe, and Mn were extremely high in the whole extension, available Mo was deficient in part of the region with a percent of 28.02 % , and water soluble Q was higher than the critical value (30mg·kg-1) with a percentage of 13.88% of the region.关键词
