The fuels that hardly pollute water body and atmospheric environment during burning are regarded as clean fuels. Liquefied Petroleum Gas (LPG), Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) are three representative clean fuels that are widely used in the shipping industry. From both ecological and economic point of view, LNG is treated as the best fuels in shipping industry by the ship-owners and Chinese government. In this paper, the wide applications of LNG-powered ships are analyzed from three aspects, including the global energy source structure, economic demands and the formulation of international conventions. Also, the functions of relevant domestic policies on how to accelerate LNG-powered ships widely used in inland waters of Yangtze river, China are summarized. At last, the reasons of the use of LNG-powered ships in inland waters of China in recent years under the impulsion of various factors are discussed in the end. 展开更多
