摘要
基于GIS的可视化、空间插值和叠加分析功能,以1982年全国684个气温台站观测数据为插值实验样本,探讨可视条件下空间插值几种主要方法的优劣及适用性,通过对年均气温预测精度的对比及陕西省年均气温预测图的分析,得出就效果而言普通克里格空间插值最优、反距离加权法次之而规则样条法相对较差的初步结果。
Based on the visualization, spatial interpolation and overlay analysis function of GPS, with the national 684 meteorological stations with an average annual temperature observation data in 1982 as an example, it presents several main spatial interpolation methods including the applicability, superiority and inferiority. Through the comparison of the predicted, accuracy of the annual temperature and the analysis of annual temperature prediction figure in Shanxi province, the conclusion is obtained that Ordinary Kriging interpolation method effect is the best. Completely Regularized Spline method is the second, and Inverse Distance Weighting method is the less.
