摘要

摘要: 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。

Abstract: The May-12 Wenchuan Earthquakein 2008 has not only huge injuries, casualties and economic losses but also serious impacts on the local eco-environment. Based on the high resolution and high precision monitoring results of hydro geochemistry obtained from the NSFC-supported project“Investigation on the mechanisms of anthropogenic and natural impacts on the decline of the travertine landscape at Huanglong the World Natural Heritage Site”, it was found that the great earthquake has remarkable influences on the hydro geochemistry of the Huanglong source spring, which recharges the Huanglong travertine-deposition stream. The influences mainly reflected in the increase in discharge, water temperature and electric conductivity as well as pCO2 of the spring, indicating the increase in fluxes of discharge, heat, calcium ion and CO2 towards the surface. However, the effect of the earthquake on the travertine landscape and CO2 release to the atmosphere remains to be assessed.
