【摘要】 天然气水合物是未来极具前途的能源,然而由于其赋存状态的特殊性,在温度或压力变化的情况下将会分解释放出巨量的甲烷气体,不仅导致海底沉积物力学性能的改变而诱发海底滑坡等地质灾害,同时也会引起全球气候的变化。因而在关注其资源前景的同时,也应该重视其潜在的灾害和环境效应。更多还原

【Abstract】 Natural gas hydrate is a future energy resource, but it will be discomposed and release large volumes of methane when environment temperature or pressure changes, which will not only alter mechanical property of the sediments causing geo-hazards such as seafloor landslide but also make global climate change. It is must taken consideration of the potential geo-hazard and environment effects causecd by utility of gas hydrate as a future energy resourse.更多还原
