| 摘 要： | 介绍了怀来CO2测点的地质条件和基本动态特征,重点分析了2000年以来测值最高值逐年升高的变化特征.逐一排除了测试管、地温、降雨等因素引起变化的可能性,与40 km外延庆松山CO2监测点类似的变化特征对比也说明这种变化不是人为因素所致.分析显示CO2测值逐年升高的特征与测点周围300 km范围内最高震级逐渐增大的特征相吻合,可能反映了京西北地区能量的逐渐积累,应力状态的不断增强的过程. |

| Abstract: | The geological conditions and principal characters of CO2 changes in Huailai county are described in brief, with the emphasis on gradually rising of the observation values year after year since 2000. Some possible influencing factors such as test pipe, underground temperature and rainfall are ruled out by research, and similar characteristic of CO2 changes in Songshan, Yanqing county, where is 40 km away from Huailai, show it is not result of artificial environment changes. Further study shows that characteristic of CO2 changes is consistent with the rising of magnitude of earthquake gradually in 300 km around, which probably indicating the process of energy-accumulation, stress-intensification. |
