基于Kriging法的森林土壤养分空间插值OA北大核心CSCDCSTPCD
Spatial interpolation of forest soil nutrients based on Kriging method
利用ArcGIS 9.3软件,采用Kriging法完成土壤养分有机质和全钾养分的空间插值.结果表明,福建省顺昌县森林土壤的有机质和全钾含量空间上存在中等程度相关.采用Kriging法的Stable和Spherical半变异函数模型表征有机质和全钾含量的空间变异特征效果最好.交叉验证表明:有机质和全钾的插值结果平均误差分别为-0.09和0.00,均方根误差( RMS)分别为16.42和2.68.
Spatial interpolation of soil nutrients was implemented with Kriging method by ArcGIS 9.3. The results showed that there was a moderate spatial correlation between soil organic matter (SOM) and total potassium (TK) content of forest soil in Shunchang County, Fujian Province. The stable and spherical, semivariogram model of Kriging method could reflected the spatial variability of SOM and TK content, respectively. The cross validation showed that the me…Pear, black spot, Alternaria, species identification, pathogenicity
