摘要
借助于地质统计学方法对汾河流域的多年平均降雨量和蒸发量的空间变异性进行了分析,揭示了多年平均降水量和蒸发量的空间变异特征,并应用Kriging方法进行空间插值.分析结果表明,汾河流域多年平均降水量和蒸发量在不同的分割距离范围内有不同的空间相关性,多年平均降水量具有比较明显的地带性,蒸发量分布变化地带性不强.
The spatial variability of the long-term mean annual precipitation and evapotranspiration were analyzed with the help of the Geostatics in this paper.The spatial variation of the precipitation and evapotranspiration over the Fenhe river basin were disclosed,and the Kriging method was used to interpolate.The results show that the precipitation and evapotranspiration have different spatial correlation in different partition range.And the distribution of the long-term mean annual precipitation has the clearer nelations to various regions than the evapotranspiration.
