| 摘 要： | 温泉是深部岩浆活动在地表的直接表现,并且向大气圈排放大量的温室气体.然而,国内尚无火山区温泉排放的温室气体通量研究报道.我国长白山火山区水热活动强烈,主要有湖滨温泉带、聚龙温泉群、锦江温泉以及火山口外围的十八道沟温泉.本文利用数字皂膜流量计测量温泉气体排放通量,并结合前人对长白山火山区温泉气体成分的研究成果,估算了研究区温泉所排放的温室气体通量.结果表明,长白山火山区温泉排放的CO2通量为6.9×104t·a-1,CH4排放通量为428.44t·a-1,与意大利Pantelleria Island火山区温泉排放的温室气体通量规模相当.本文的测试结果表明:数字皂膜流量计在火山区温室气体排放通量估算研究中的应用是可行的.

| Abstract: | Hot springs, which belong to the direct manifestations of deep-derived magma activities, are ample and intensive in Changbaishan volcanic field, NE China. Greenhouse gases emitting from hot springs take up an important part of the total flux contributed by the whole volcanic field. However, there remains no research on greenhouse gases flux estimation of hot springs in volcanic fields of China. A new apparatus named GL-103B digital bubble/liquid flowmeter is used to measure the gas fluxes of the Lake shoreline hot spring belt, Julong hot spring area, Jinjiang hot springs and 18daogou hot springs in changbaishan volcanic field. Combining with the previous studies on gas compositions, the total flux of greenhouse gases emitting from hot springs in Changbaishan volcanic field has been estimated. The results of greenhouse gases flux in this area, 6.9×104 t·a-1 for CO2 and 428.44t·a-1 for CH4, could be compared to that of Pantelleria Island volcano in Sicily, Italy. As is revealed by this study, the digital bubble/liquid flowmeter could be considered as a suitable choice for greenhouse gases flux estimation of hot springs in volcanic fields. |
