This paper analyzed the development of different types of natural gas flow zones in China, and then di-vided all provinces into four flow types: non-flow zones, output centers, input centers and exchanging centers. Next, we analyzed the concentration and diffusion characteristics, current spatial pattern and evolution of source and terminal regions of natural gas resource flows. The numbers of non-flow zones, output centers, input centers and exchanging centers al stabilized during the Eleventh Five-Year Plan period. The number of output centers is smal but the quantity of flow is large. The number of input centers is large and they are widely distributed. Generally speaking, it presents a significant characteristic of centralized output and dispersed input in geographic space. The current situation for China’s natural gas output source has random distribution characteristics, but the terminal re-gions of natural gas flow have strong positive spatial correlation, presenting a significant spatial agglomeration pattern. Shandong, Jiangsu, Zhejiang and Shanghai have a high-high agglomeration mode, but Yunnan, Sichuan, Tibet, Qinghai and Gansu have a low-low agglomeration mode. Spatial pattern changes in China’ s natural gas output zones had three different stages: relatively stable from 2001–2003; moved northwestward, expanded in space, and widely dispersed during 2004–2006; and transferred to the east, spatialy contracted and significantly concentrated during 2007–2011. Spatial pattern changes in China’s natural gas input zones have two stages: ex-panded in east-west direction while contracted in north-south direction during 2001–2005; and relatively stable in spatial structure with intensification from 2006–2011.%本文首先分析了中国不同天然气流动类型区的发展状况，并将全国划分为输流中心、汇流中心和交流中心三种流动职能类型，然后重点分析了天然气源汇地空间格局现状集散特征以及源汇地空间格局的演化规律。主要结论如下：(1)天然气无流地、单向输流地、单向汇流地和双向交流地在“十一五”期间其数量都趋于稳定；天然气输流中心数量少、流量大，而汇流中心数量大、分布广，在地理空间上呈现出显著的集中输流和分散汇流的特征。(2)中国天然气各输出源地的空间现状具有随机分布的特征，而资源汇地具有较强的正自相关性，呈显著的空间集聚模式。其中，长三角两省一市以及北部的山东省表现为“高－高”集聚，而云南、四川、西藏、青海、甘肃地区则呈现出“低－低”集聚特征。(3)中国天然气源地空间形态变化分三个不同发展阶段：2001~2003年相对平稳，2004~2006年西北向移动，空间扩张，分散化明显，2007~2011年东向转移，空间收缩，密集化特征显著；我国天然气汇地空间形态变化分两个不同的发展阶段：2001~2005年东西向扩张、南北向收缩，2006~2011年空间结构相对平稳，密集化趋势明显。
