摘要:
随着空间降水信息需求的日益增加，降水的空间插值已被广泛应用，而不同的插值方法因不同的地区和研究目的产生不同的效果。采用新疆18个国家基本站点1957-2000年的日平均降水数据，应用地信软件Arc GIS中的地统计学模块进行空间降水插值实验，分别采用反距离加权法和克里格方法探讨了新疆降水的空间分布，分析发现：两种插值方法在分析区域降水空间分布方面各有优缺点，在整体分析上，克里格插值法要优于反距离加权法，但在局部地区的分析上，反距离加权法插值结果较为理想。
Abstract:
With the increasing needs for spatial precipitation information,spatial interpolation method of precipi-tation is widely used.Different precipitation interpolation methods for different study areas and study aims will have different results.Taking daily average precipitation data from 1957 to 2000 of country basic stations in Xinjiang,using the geo-statistical model of ArcGIS to investigation spatial interpolation is carried.The result show that the two methods have their good and bad aspect respectively.Further,the result of Kriging method is more perfect in the whole analysis,but the IDW method is better in the partial analysis.
