摘　　要：实验利用反距离权重法、样条函数、克里格法三种插值方法对我国森林病害发生的空间分布特征进行了比较分析。研究结果表明:反距离权重法的插值结果与实际观测点的相似度最高,在地图显示中反距离权重法估计的图像也最光滑和逼真,因此在森林病害监测中可选用反距离权重法进行估计,获得较为真实的空间分布特征,为利用地理信息系统对我国森林病害监测提供方法指导。Using inverse distance weighted method, Spline and Kriging interpolation method to analyze spatial distribution of our country forest disease, results showed that, interpolation results of the inverse distance weighted method has the max- imum similarity with actual observations point, on the map display in the inverse distance weighted method to estimate the image also the smooth and realistic. Therefore, in the forest disease monitoring may choose to use the inverse distance weighted method to estimate, get more real spatial distribution characteristics, for the use of geographic information system to our country forest disease monitoring guidance.
