Abstract: In order to research possible influences of the adjustment of plant distribution on the development of thunderstorm over Leizhou Peninsula,mathematic statistic methods,including correlation analyses,11 kinds of fitting models and all variation regression methods,were used for analyses and research.The results show that the average trend of the number of annual thunderstorm days is descending obviously,and there are thunderstorms in all seasons,in which warm thunderstorm has taken up the most part,and the high frequency is found from May to September,and the starting and ending dates of thunderstorm have great annual discrepancy.The vegetation structure has improved along with the reduction of rice fields and the area increment of sugarcane and fruit planting,which results in the decrease of the number of thunderstorm days;the change of the characteristics of winter spare fields,which is caused by the planting of vegetables,limits the formation of thunderstorms during the start of winter and end of spring.Meanwhile,the area adjustment of peanut planting has little influence on the variation of thunderstorm days.The adjustment of principal crops distribution,such as rice,sugarcane,fruit and vegetables,may have obvious influence on the formation of thunderstorms,and sugarcane has the largest effect,followed in turn by rice,vegetables and fruit,and the adjustment of crops distribution has little influence on the starting and ending dates of thunderstorms.
