简单介绍了高程异常多项式曲面拟合方法的数学模型,以25 km2测区为实例,选取4种已知拟合点布点方案,分别采用四、五、六参数的曲面拟合法与移动曲面拟合法对高程异常进行拟合,并将拟合成果与四等水准测量成果进行比较、分析,得出一些具有实用意义的结论。
簡單介紹瞭高程異常多項式麯麵擬閤方法的數學模型,以25 km2測區為實例,選取4種已知擬閤點佈點方案,分彆採用四、五、六參數的麯麵擬閤法與移動麯麵擬閤法對高程異常進行擬閤,併將擬閤成果與四等水準測量成果進行比較、分析,得齣一些具有實用意義的結論。

The article briefly introduces the method to the maths model of height anomaly surface fitting. Taking one about 25 km^2 survey area as an example, it selects the distribution scheme known fitting points,respectively adopts 4,5, 6 parameter surface fitting legitimate and mobile surface fitting method to fit the height anomaly, then compares and analyzes the fitting results with fourth level measured results, and finally draw some oractical and significant conclusions.
