Spatial Interpolation of Winter Wheat Annual Average Water Requirement Based on ArcGIS
摘要
Abstract
With the increasing needs for spatial winter wheat water requirement information,spatial interpolation method of water requirement is widely used.Different water requirement interpolation methods for different study areas and study aims will have different results.However,there are no absolute optimal interpolation methods unconsidering certain conditions.This paper selects four kinds of commonly used spatial interpolation methods for spatialization of annual winter wheat water requirement and compares different spatial interpolation methods via 25 meteorological stations around the Henan province.By comprehensive analysis and comparison of different spatial interpolation method,error of spatial estimate of annual winter wheat water requirement in Henan province is: IDW〈Kriging〈Cokriging〈GP.关键词
