| 摘 要： | 本文是根据１９９４年在南极中山站首次使用数字触发地震仪测量的冰崩，研究南极中山站地区冰崩规律及其与自然环境（温度、风速等）的关系，这对于考察船在南极的安全航行以及科考人员的人身安全都有极为重要的意义；并且对于南极冰川、冰山、冰盖等方面的科学研究有参考价值。结果表明，１～９月份冰崩次数曲线呈口朝上抛物线型变化，１０～１２月冰崩次数急剧增加。冰崩曲线与月最低气温、最高气温、月平均气温三者的拟合曲线吻合得很好，即冰崩次数随气温持续上升而增加，风速与冰崩的关系却与此相反

| Abstract: | In this paper,ice avalanche was measured by digital trigger seismograph in Zhongshan Station to study the relation between ice avalanche regularity and nature surroundings (temperature,wind speed, etc.).It's important to the safe journey and the safety of scientists in Antarctica.It will also be of much help to the research of Antarctic glacier,iceberg and ice sheet.The result shows that the change of frequency of ice avalanche from January to September is parabolic with the mouth upwards and from October to December the frequency increases rapidly. As the temperature rises, the frequency of ice avalanche increases.The relation between the frequency and the wind speed is opposite. |
