摘要: 以1965—1999年河北省逐月平均气温为研究对象,采用一元线性回归法和IDW(Inverse Distance Weighted)相结合的方法,将温度插值到河北省整个区域,绘制河北省温度空间分布图,实现河北省年内各月平均气温空间填图;同时,分析了河北省冬季和夏季各月的月平均温度的误差精度。结果表明:插值的结果与观测值的相关系数(R)在12个月均大于0.82,显示插值方法具有较好的模拟精度,可用于气温的空间插值和特征分析。

Abstract: The monthly air temperature data from 1965 to 1999 in Hebei Province was interpolated by linear regression method and inverse distance weighted (IDW) method, and their spatial distribution maps were given. The errors of air temperature interpolation in each month of winter and summer indicate that the correlation coefficients between interpolation results and observation values in 12 months are all more than 0.82. It shows that the interpolation method is better, which can be used to interpolate air temperature and to analyze the spatial characteristics in Hebei province.
