The correct use of Chinas natural gas resources, grasp its future development trend, and formulate the development strategy of natural gas industry according to Chinas own situation. It is particularly important today when the bottleneck of resources is becoming more and more prominent. With the rapid development of gas industry in our city, as a new field of application of gas has been considerable development, application range from the car with gas to residents with gas, self get coordinated development of social and economic benefits, analysis the characteristics of operation is of great significance for natural gas in the cities and towns should be used. This article mainly compares the different gas source selection from small towns, analyze its characteristics and put forward small towns of different gas source selection basis: the basic way of piped natural gas is proved that large-scale natural gas transportation, the pipeline is the most economical and effective way of transportation. In addition, other gas sources can be selected as the source of urban gas supply. Such as liquefied natural gas (LNG), is the na
