复杂地貌类型区土壤属性空间插值方法研究

摘要土壤属性空间插值方法是土壤变化的重要检测方法，是“数字土壤”的重要研究内容。本文简单通过对青海湖流域复杂地貌的土壤酸碱度研究，介绍了土壤属性空间插值的常用方法，并对土壤属性即土壤酸碱度空间插值精度验证的方法和指标做了进一步的阐述说明; 充分考虑各种影响土壤酸碱度的因素，将不同插值方法及其精度进行对比，得出最优的插值方法。对不同空间插值方法产生的不同精度结果，结合了青海湖流域的具体实际情况，给出了具体的解释和说明。最后从插值方法的选择、验证指标的选取两个方面对青海湖流域复杂地貌土壤属性空间插值方法的研究进行总结。69260

Complex Geomorphic Type Soil Properties Spatial Interpolation Methods

Abstract

Soil properties spatial interpolation methods is an important detection method, the changes in soil is an important content of "digital soil". Simple this article through to the qinghai lake basin complex landform soil PH, soil properties spatial interpolation methods are introduced, and the soil properties on the soil PH value space interpolation accuracy verification explains further the method and index; Fully consider various factors that affect the soil PH, compare different interpolation methods and their accuracy, it is concluded that the optimal interpolation method. Of different spatial interpolation methods produce different precision of the results, on the basis of the actual situation of the qinghai lake basin, gives a detailed explanation and illustration. Finally, from the choice of interpolation method validation index the two aspects of the selection of soil properties of qinghai lake basin complex landform summarized the research of spatial interpolation method.

The paper has 11 pictures,6 tables,17 references.

Key words: soil spatial interpolation prediction error Qinghai lake
