According to the data of automatic laser raindrops spectrometer from 2012 to 2014,the paper,with the Gamma distribution fitting method,sums up the localization of Z-I relationship. By reusing variational method for radar echo,we have automatic rainfall station data points on the calibration. It is suitable for the actual business need localization of Z-I relationship. The improved Z-I is applied to estimate and forecast the precipitation in Langfang city in April 11,2015. The results show that the precipitation estimation accuracy is improved by using rain gauge and rainfall automatic station data,and the spatial distribution of precipitation is better than the original RPG precipitation.
