山东省文登市耕层土壤有机质的空间分异特征研究
STUDY ON SPATIAL VARIATION CHARACTERISTIC OF TILLED TOPSOIL ORGANIC MATTER OF WENDENG CITY SHANDONG
摘要
Abstract
Basing on field sampling and analysis on soil samples, this paper determines soil organic matter alue of. With Arcgis platform, it analyzed Wendeng spatial characteristics of topsoil soil organic matter using kriging of statistical analysis module, and choosed the optimal contrast kriging interpolation model. The results showed that topsoil organic matter had large spatial variability in Wendeng and the best theoretical model is Tetraspheri-cal model fitting organic matter content. It also made sure that the CO/sill lvas 0. 86. The spatial correlation was very weak of topsoil organic matter which was mainly caused by the human activities. The farming management should be improved because of the low organic matter content in the topsoil.关键词
