摘要
城市暴雨内涝计算的精度取决于暴雨数据的准确性。分别采用反距离加权插值、样条函数插值、克里金插值三种方法,对郑州市暴雨数据进行插值精度比较、交叉检验结果精度分析,并在城市暴雨内涝计算中对三种降雨插值结果进行验证。结果表明:克里金插值结果要优于反距离加权插值和样条函数插值结果,能够满足区域暴雨内涝灾害计算的精度要求。
The calculation accuracy of the urban rainstorm water logging depends on the accuracy of the heavy rainfall data. By comparing the accu- racy of Zhengzhou rainstorm rainfall interpolation data by using the Kriging method, IDW method az^d spline method, the best rainfall interpolation method was analyzed, and also the interpolation results were checked by using the urban storm rainstorm data. The results show that the Kriging method is better than both of IDW and spline methods, and ensures the reasonable accuracy range optimization,
