摘要:
在地统计学和地理信息系统支持下，采用多种插值方法对黄土高原中游降水量进行了空间插值研究。结果表明：地统计学方法优于传统的反距离加权插值法、径向基函数插值法，对不同数目气象站点的插值相对误差较稳定。通过空间插值得到了黄土高原中游降雨量分布图，由该降水量分布图可知，黄土高原中游降雨量总体呈现西北低、东南高的态势，界限很明显。
Abstract:
With the support of geo-statistics and geographic information systems,the spatial interpolation research on precipitation in the middle part of the Loess Plateau was carried out through using a variety of interpolation methods.The following preliminary conclusions can be gained.The geo-statistical method is better than the traditional inverse distance weighted interpolation and radial basis function interpolation method,and interpolation was implemented with a compared stable relative error in the meteorological stations of different numbers.Through spatial interpolation in the Loess Plateau,a rainfall distribution map can be made,depicting that the overall rainfall in the middle of the Loess Plateau turns on the trend of low in northwest and high in southeast,and the boundaries are obvious.
