不同插值方法对土壤养分空间插值结果的影响——以寿西湖农场为例

Effects of Different Interpolation Methods on Spatial Interpolation of Soil Nutrients——Taking Shouxihu Farm as an Example

土壤养分具有空间变异性规律,养分插值的结果直接关系到耕地地理评价的精度与可用性。国内多位学者已经对不同插值方法进行了对比研究,但多数是基于单一养分插值结果的分析。该研究选取安徽省寿县寿西湖农场平原区为研究区,对比分析不同插值方法得到的插值结果,探讨其对养分插值结果精度的差异,发现最佳插值方法,用来指导更加合理的养分空间管理。

Soil nutrients have spatial variability,and the results of nutrient interpolation are directly related to the accuracy and availability of farmland geographical evaluation.Various interpolation methods have been compared and studied by many scholars in China,but many are based on the results of single nutrient interpolation.This study selected shou county in anhui province Shouxihu farm plain as the research area,the interpolation results of comparative analysis of different interpolation methods,discussed the differences in the nutrient interpolation result accuracy,found the best interpolation method,used to guide more reasonable space for nutrient management.
