| 摘 要： | 天然气水合物富含温室气体甲烷,且资源量巨大,对气候变化又十分敏感,在全球变暖的背景下其气候效应倍受关注,近年来的研究工作又取得了一些新进展.首先,天然气水合物资源量的估算进一步精确,海洋中天然气水合物资源量的最新估算值仅为原先的1/5,从根本上限制了其气候效应的显著性;其次,大气中来自天然气水合物的甲烷通量被重新评估,...

| Abstract: | It has been strongly discussed that gas hydrates play a key role in global climate changing,in terms of huge inventory,sensitivity to the climate change and the greenhouse effect.The recent advances in climatic effects study of gas hydrates could be generalized as follows.Firstly,the inventory was accurately constrained by the new data,one fifth of the previous estimate,which basically restricted the possibility of gas hydrates effect on the climate.Secondly,the flux of methane escaped from gas hydrates to ... |
