- Title:
- Application of the Spatial Interpolation Methods to the Study on Micro-DEM
- Keywords:
- tillage measures; GIS; Centimeter DEM; spatial interpolation

- 摘要:
- 以地统计学常用的均方根预测误差、半变异函数云图和误差图等为精度量化指标，对等高耕作、人工掏挖、人工锄耕和直线坡面耕作措施下微地表高精度DEM的建立方法进行了探讨，以寻求不同耕作措施下构建微DEM的最佳插值方法。结果表明：等高耕作措施微地表采用析取克里格插值法精度较高；人工掏挖措施微地表采用局部多项式插值法效果较好；人工锄耕措施微地表采用规则样条函数的径向基函数插值方法精度较好；对于直线坡面上述几种插值方法的精度差异不大。本研究为建立不同耕作措施下微DEM提供理论基础，并服务于黄土坡耕地土壤侵蚀机理的研究。
- Abstract:
- This article choose the predictive error of root-mean-square, semivariogram and error cloud as quantitative index to explore the interpolation methods of Micro-DEM of different tillage measures in order to find the best interpolation method of the construction of Micro-DEM. The results show that: The disjunctive kriging based on geostatistical menthod is more better than others for contour tillage; Artificial digging should choose the method of local polynomial interpolation; Artificial hoeing should choose radial basis functions based on completely regularized spline; There is no more differences for linear slope among different spatial interpolation methods. This research is the theoretic base for interpolation methods of Micro-DEM under the different measures, and facilitate the further study of the mechanism of soil erosion in the sloping plantation of the Loess Plateau
