美国天然气进口来源分两种，一是管道天然气进口，一种是液化天然气进口。其中，管道天然气进口受限于地理环境，仅有加拿大和墨西哥两个国家。而LNG进口来源地则较为分散，共包括17个国家。总体来看，美国天然气进口横跨美洲、中东、非洲、亚太、欧洲和欧亚大陆等全球五大区域。

The United States imported natural gas source of two，A natural gas pipeline is imported，One is liquefied natural gas imports。Among them，Natural gas pipeline import is restricted to the geographical environment，Canada and Mexico only two countries。And LNG source of imports is more in scattered，Including 17 countries。overall，The United States imported natural gas across America、Middle East、Africa、asia-pacific、European and Eurasian continent of global 5 large area。

　　美洲一直是美国进口天然气的最大来源地，2011年，美国从美洲进口管道天然气量在总进口量中的占比为94%，远高于其他区域。

America has been the biggest source of natural gas imports from the United States，2011 years，The United States imported from America natural gas pipeline in the amount of total imports of ratio is 94%，Is far higher than other areas。

　　日本天然气进口来源地横跨美洲、中东、亚太、欧洲、非洲等全球五大区域。在亚太方面，日本进口的天然气量处于下行趋势，但仍然是日本天然气进口的主要来源。其中，印尼、澳大利亚、马来西亚是日本进口天然气的三大来源地，2010年，这三个国家向日本出口的天然气超出了日本进口天然气总量的一半。

Japan's natural gas source of imports across America、Middle East、asia-pacific、Europe、Africa and other global 5 large area。In the aspects，Japan imports of natural gas in a descending trend，But still is the main source of Japanese imports of natural gas。Among them，Indonesia、Australia、Malaysia is Japan imports of natural gas three big source，2010 years，The three countries to Japanese exports of natural gas beyond the half of total gas imported from Japan。

　　德国天然气进口来源地只有6个国家，分别是丹麦、英国、挪威、荷兰、俄罗斯和法国，全部集中在欧洲和欧亚大陆。俄罗斯、挪威、荷兰是德国进口天然气的三大来源地。俄罗斯一直是德国进口天然气的最大来源地，2011年德国从俄罗斯进口天然气占当年德国天然气进口总量的39.8%。

German gas source of imports only six countries，Were Denmark、British、Norway、The Dutch、Russia and France，All concentrated in Europe and Eurasia。Russia、Norway、The Netherlands is Germany gas imports three big source。Russia has been the biggest source of natural gas imported from Germany，2011 Germany from Russian gas imports in Germany accounted for 39.8% of total imports of natural gas。

　　美国、日本、德国分别是目前美洲、亚太、欧洲三大区域最大的天然气进口国，通过观察这三个国家天然气进口规模和结构的变迁，可以总结出以下四大规律：就近原则；势力范围划分明显，按照就近原则，美欧分别把美洲及欧洲和欧亚大陆划入自身的势力范围，而亚太的天然气进口来源地则主要集中在中东；与天然气进口来源地关系良好，在当地拥有天然气权益并积极开展天然气等能源国际合作；临近国家集中策略，由于天然气具有较前的地域性，长距离运输增加成本严重影响其经济性，因此，各国进口天然气主要是从临近的几个国家集中进口。

The United States、Japan、Germany is now America respectively、asia-pacific、European three large area of the largest natural gas importers，Through the observation of the three countries natural gas imports and the development of the structure of the scale，Can be summed up the following four laws：Principle nearby；Obviously divided into spheres of influence，According to the principle nearby，The us and Europe to America and Europe respectively and Eurasia into their own sphere of influence，And the Asia Pacific gas source of imports are mainly concentrated in the Middle East；A good relationship with natural gas source of imports，Owns the local gas rights and actively carry out natural gas energy international cooperation；Near the national focus on strategy，Because the natural gas has a former region，Long distance transportation cost the serious influence its economy，so，Various countries import natural gas from near the main focus on importing countries。

　　对中国的启示为：巩固亚太和欧亚大陆，积极从邻近区域进口天然气；进一步加强从中东获取的天然气进口；积极争取从美洲、非洲的天然气丰沛国进口天然气；在与各个天然气进口目标国建立良好国际关系的同时，通过在全球进行天然气资源战略布局，获取当地的天然气权益，并与当地全面开展整条天然气产业链以及其他能源领域的国际合作。

Revelation to China for：Consolidate the asia-pacific and Eurasia，Positive from neighboring area imported gas；Further strengthening of the gain of natural gas imports from the Middle East；Actively from America、Africa's natural gas plenty countries import natural gas；In all natural gas imports target countries and establish good international relations at the same time，Through the worldwide natural gas resources strategic layout，Get local gas rights and interests，And with the local overall article the gas chain and other international cooperation in the field of energy。
