In recent years,due to the large geographical differences and climate vary,resulting in lightning activity of a certain spatial distribution of lightning occurs often accompanied by rain and other weather,to people′s lives and the entire ecosystem constitute a threat. In this paper,using of OTD/LIS and ATD location data from 2010 to 2014,statistical methods were employed,the spatial distribution of lightning,daily,monthly change characteristics of lightning density,and latitude and longitude variation characteristics were studied. Results showed that :The lightning density spatial distribution of these two observations have good similarity. Lightning density statistics are mainly concentrated in China ′s coastal regions,and in a relatively small area northwest of lightning activity,lightning frequency distribution of the next day,two observations have some differences.According to OTD/LIS data,frequency of lightning monthly change showed a single peak trend,while data for the ATD monthly change of lightning frequency showed a single valley-single-peak variation type. For the frequency of lightning latitude distribution,these two observations have greater difference.
