2008年5月12日的汶川特大地震不仅造成了惨重的人员伤亡和巨大的经济损失,而且对当地生态环境产生了严重的影响。本文根据黄龙钙华景观退化的人为和自然影响机理研究获得的部分高分辨率和高精度水文地球化学监测数据分析发现,大地震通过诱导控制黄龙源泉的深源断裂活动对源泉的水文地球化学产生了显著影响,主要表现为地震后泉流量、水温、电导率和CO2分压升高,反映出地震增加了地下向地表的水、热、钙离子和CO2通量。然而,地震对从泉水中沉积的钙华景观的后续影响以及汶川地震造成深源CO2向大气CO2释放对全球碳循环的影响,有待进一步的监测评估。
The Wenchuan Earthquake on May 12, 2008 not only caused heavy casualties and huge economic losses, but also had a serious impact on the local ecological environment. According to some high-resolution and high-precision hydrogeochemical monitoring data obtained from the anthropogenic and natural mechanism of landscape degeneration of the Huanglong travertine, we found that the hydrogeochemistry of the source spring was controlled by inducing and controlling the deep-source fault activity of Huanglong source Significantly, the spring flow, water temperature, electrical conductivity and partial pressure of CO2 increased after the earthquake, reflecting that earthquakes increased the water, heat, calcium and CO2 fluxes from the ground to the surface. However, the subsequent impact of earthquakes on the travertine landscapes deposited from springs and the impact of deep-sea CO2 release to the atmosphere on the global carbon cycle caused by the Wenchuan earthquake need to be further monitored and evaluated.
