基于Kriging 法的凉州区耕地土壤微量元素的空间插值研究
Study on Spatial Interpolation of Farmland Soil Microelement of Liangzhou District Based on Kriging Method
摘要
Abstract
The effective state content of soil microelement elements copper, zinc, iron, manganese of the study area was determined, the software of Arcgis geographic information system was selected, the spatial of variability Kriging interpolation method were studied using the statistical analysis module of the Geostatistics Analyst on microelement elements. The results showed that the average of effective state zinc content was 0.50 mg/kg, which classification standard of Ⅳ level in gansu province nutrient, the average of effective manganese content was 11.01 mg/kg, the effective copper content was1.01 mg/kg, the effective iron was 14.6 mg/kg, which classification standard of Ⅱlevel in gansu province nutrient. Among them the highest areas of effective iron content was Huangyang district, Zhangyi district was the lowest;the highest effective manganese content was Fengle district, Qingyuan area was the lowest; the highest effective copper content was Huangyang district, Zhangyi district was the lowest; the highest effective copper content was Yongchang district, Zhangyi district was the lowest .关键词
