摘要:

对不同的地貌区进行空间内插时选择的适宜方法不同,以典型丘陵地貌区长春市净月潭地区的高程为研究对象,用ArcGIS 9.2分别作反距离权重法、最近邻点法、趋势面分析和克里金法做高程内插。应用交叉检验方法对其内插的精度作出分析,检验其科学性和可靠性,得出反距离权重法、最近邻点法、趋势面法、样条函数法和克里金法高程内插的不同精度,并对各种方法的适用性进行讨论。结果表明最近邻点法精度最高,以下依次为普通克里金插值法、样条函数、反距离权重法、趋势面法。为类似于净月潭地区的丘陵地貌区高程内插提供选择参考。

关键词: 空间内插, 反距离权重法, 趋势面分析, 克里金内插法

Abstract:

The suitable method used to realize spatial interpolation of different landforms is different. Elevation of Changchun Jingyuetan area is the research object, this area is typical hilly and gully region,we interpolated elevation with inverse distance weighting, nearest neighbor,trend interpolation and Kriging on ArcGIS9.2. We obtained the accuracy of elevation of inverse distance weighting method, nearest neighbor, trend surface method, spline function and Kriging with Cross Validation, the conclusion is the nearest neighbor is the most accurate, followed Kriging, spline function, elevation of inverse distance weighting method, trend surface method. This research provide reference of selection for interpolation of the elevation data such as Jingyuetan area of hill landform.

Key words: spatial interpolation, IDW, trend interpolation, Kriging
