以便在 Leizhou 半岛上在雷雨的发展频率上研究植物分发的调整的可能的影响，数学统计方法包括关联分析， 11 种恰当的模型和所有变量回归方法，被用于分析和研究。年度雷雨天的数字的平均趋势显然正在下，并且在所有季节，温暖的正午以后的雷雨在收起大多数部分有雷雨的结果表演，和高频率从5月被发现到9月，并且雷雨的开始并且结束的日期有大年度差异。植被结构与稻田的减小和甘蔗并且水果种的区域增长一起被改进了，它导致雷雨天的数字的减少；在冬季的特征的变化业余领域，被种蔬菜引起，在早冬季和迟了的春天限制雷雨的形成。同时，花生种的区域调整几乎没在雷雨天的变化上有小影响。主要庄稼分发的调整例如米饭，甘蔗，水果和蔬菜，可以在雷雨的形成上有明显的影响，并且甘蔗有最大的效果，由米饭，蔬菜和水果接着列在后面，并且庄稼分发的调整几乎没在雷雨的开始并且结束的日期上有小影响。

英文摘要：

In order to research possible influences of the adjustment of plant distribution on the development frequency of thunderstorms over the Leizhou Peninsula, mathematic statistic methods, including correlation analyses, 11 kinds of fitting models and all-variable 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 post-midday thunderstorms have taken up the most part, and high frequency is found from May to September, and the starting and ending dates of thunderstorms have a great annual discrepancy. The vegetation structure has been improved along with the reduction of rice fields and the area increment of sugarcane and fruits planting, which results in the decrease of the number of thunderstorm days the change in the characteristics of winter spare fields, which is caused by the planting of vegetables, limits the formation of thunderstorms in early winter and late spring. Meanwhile, the area adjustment of peanut planting has little influence on the variation of thunderstorm days. The adjustment of principal crop distribution, such as rice, sugarcane, fruits and vegetables, may have obvious influence on the formation of thunderstorms, and sugarcane has the largest effect, followed in turn by rice, vegetables and fruits, and the adjustment of crop distribution has little influence on the starting and ending dates of thunderstorms.
