| 摘 要： | 介绍常用的地理信息空间分析插值方法,选择"灿都"台风降雨过程,以南宁市及其周边的212个站点分别利用距离反比法、克吕格法和梯度距离平方反比法进行插值,并利用未参与插值的30站点计算每种插值方法结果的平均绝对误差(MAE)、平均相对误差(MRE)、最大相对误差(MMRE),结果表明,梯度距离平方反比法在实验中较好.

| Abstract: | By using inverse distance weighting(IDW)method,Kriging method and gradient plus inverse distance squares(GIDS)method,the precipitation values of Nanning City and its surrounding 212 automatic weather stations were interpolated during "Chanthu"typhoon period.Then basing the other 30 stations precipitation without involving in Interpolation,the mean absolute error(MAE),mean relative error(MRE)and max mean relative error(MMRE)were calculated.The results show that GIDS is the better method in the experiment. |
