畦田灌溉模拟中田面微地形空间分布插值方法改进
田面微地形是影响灌溉过程及灌溉性能的重要因素之一。针对灌溉模型中田面微地形的插值问题,该文在比较Kriging插值、三次样条插值和反距离加权插值的插值精度和程序运行时间的基础上,进一步分析了不同规格畦田下Kriging插值程序运行时间随插值网格数的变化趋势,提出了利用Kriging插值和三次样条插值及反距离加权插值进行组合插值的方法,并将不同中间插值网格数经组合插值所得田面高程数据用于灌溉模拟。结果表明,Kriging插值所得田面高程的精度最高,程序所需运行时间最长;而三次样条插值和反距离加权插值所需运行时间非常短,但精度较低。为了同时满足田面高程的插值精度和模型计算效率的要求,选用Krigi...

China Institute of Water Resources and Hydropower Research, Beijing 100048, China） Surface micro-topography is one of the most important factors affecting irrigation process and performances. In view of the interpolation problem of surface micro-topography in irrigation model, using observed data on surface relative elevation of 4 different size ridge field, this study firstly compared the interpolation accuracy and program running time of Kriging interpolation, cubic spline interpolation and inverse distance weighted interpolation（IDW）, and then analyzed the trend of Kriging interpolation program running time with the change of interpolation grid numbers under different sizes of ridged field. Furthermore, the combination interpolation methods of Kriging interpolation and cubic spline interpolation, and Kriging interpolation and inverse distance wei |
