| 摘 要： | 运用反距离加权插值法、三角线性插值法、Hermite插值对法同一地区的8种重金属的空间分布进行了插值分析,并对结果进行分析对比,发现该地区除汞适合三角线性插值法以外其他均适合反距离加权插值方法.证明了重金属分布的含量与特点决定了插值方法的选取,进一步丰富了插值法对重金属的空间分布实际应用,并结合区域的功能进行分析,使空间分布更能结合于实际应用.

| Abstract: | Inverse distance weighted, triangular linear interpolation, Hermite interpolation are used to analyze the distribution of eight kinds of Heavy Metals in the same area, and the results were compared and it is found that only mercury is suitable for linear method and others are suitable for IDW method. It proves that the choice of an interpolation method depends largely on the distribution of heavy metals content and characteristics, which further enriches the interpolation methods＇ practical application of heavy metals spatial distribution. In combination with the analysis of regional functions, the spatial distribution is made more suitable for practical use. |
