中文摘要：

依据行星对应区理论,金星下合会给对应区域带来较多降水,并导致洪涝灾害。以2015年华南后汛期暴雨为例,研究了在金星下合为主的几种行星格局影响下该区域的暴雨发生规律。结果表明：金星下合期间,对应区域同纬度易产生多个云团;金星下合产生暴雨的灾害效应一般由月球回归触发;在行星布局分散的情形下,暴雨也呈分散性布局。暴雨洪涝灾害与星体格局及其变化等有着密切关系。

英文摘要：

According to the planetary corresponding area theory,inferior conjunction of Venus can bring more precipitation and rainstorm disasters to the corresponding area. Taking rainstorm in southern China in 2015 summer and fall as an example,we explore the characteristics and regularities of rainstorm caused by the inferior conjunction of Venus and several planetary distribution patterns. Several conclusions as following：（ 1） A plurality of clouds will appear in same latitude of corresponding area during the inferior conjunction of Venus.（ 2） The disaster effective of rainstorm can be triggered by lunar regression.（ 3） The rainstorm will appear scattered distribution in the situation of disperse layout of planets. It is found that the drought and flood disasters are bound up with planetary distribution and its change.
