2003~2008年中国东部土壤相对湿度的冠谐分析

Application of Spherical Cap Harmonic Analysis to Soil Moisture in Eastern China for 2003~2008

  • 摘要: 利用2003~2008年在京津冀地区观测的146个观测站点土壤相对湿度资料,建立了年变化趋势球冠谐模型。球冠极点为东经115°,北纬38°,球冠半径为5°,球冠模型最高展开至8阶。根据模型,计算并分析了该球冠内土壤相对湿度在10cm、20cm和50cm深度年变化趋势空间分布特征。

     

    Abstract: Using 146relative soil moisture observe stations data from 2003to 2008in the Beijing、Tianjing and HeBei area,we have established a spherical cap harmonic model of the annual trend.Spherical cap pole located in longitude 115°,latitude 38°.The radius of the spherical cap is 5degree while the maximum degree expands to 8degree.According to the spheical cap harmonic model,we calculate and analyze the characteristics of the relative soil moisture annual linear spatial distribution in 10cm 、 20cm and 50cm depth.
