摘　　要：根据海口市连续10年降雨统计资料分析降雨对该地区架设无线激光通信设备的影响。研究了海口地区降雨特点对光链路传输的影响,对链路功率余量,误码率和最大通信距离进行了分析和计算。结果显示降雨严重影响系统的通信时长和通信距离。为海南以及类似气候条件地区建立大气激光通信系统的设计提供了参考。The paper analysis rainfalrs effect in setting up the wireless laser communication equipment in haikou city according to rainfall statistics data of Haikou city within 10 years.The transmission effect of the communication link in rain channel in HaiKou city is researched .The link-margin ,bit-error-rate and the maximum distance are analyzed and calculated as well. The results show that communication hour and communication distance are very sensitive to rainfall. It provides reference for HaiNan and other with similar climatic condition to design to establish the wireless laser communication.
