摘　　要：对云南地区12个水氡点资料进行了统计分析，发现水氡浓度普遍存在月变现象，这种月变是与月球运动有关的潮汐响应。孟连7．3级震前，较多水氡点月变幅度普遍显示异常，异常量和异常时间在平面分布上有一定规律可循。After analyzing the data of 12 water radon points in Yunnan area, it is discovered that the radon concentration in ground water has month wave phenomena (month variation), which is the tide response related to the moon movement. Before the Menglian M7. 3 earthquake, the month wave amplitudes at most of the water radon points appear anomaly,and the size and time of anomaly have their own pattern in the plane distribution.
