基于GIS的传统插值方法比较研究——以山东省多年平均气温为例

Comparative Study of Traditional Temperature Interpolation Method Based on GIS——Taking Multi-years Average Temperature in Shandong Province as an Example

利用GIS软件空间内插方法,采用7种不同的传统插值方法对山东省多年平均气温进行内插,生成内插表面模型并进行误差分析。结果表明,以误差均值为标准,趋势面插值方法较优,自然领域插值方法误差最大,同时,传统内插方法无法加入高程影响因子。

Using spatial interpolation methods by GIS, the average temperature is interpolated by 7 kinds of traditional interpolation method in Shandong Province, generating the interpolated surface model and analyzing the error, we can draw the conclusion by comparison： the trend is superior, the natural has the larger error, and the traditional interpolation methods cannot be added to the elevation factor.
