Abstract：Research purposes: Longyan city，located in the west of Fujian Province，is an important node of the connecting the southwest region of Fujian Province with the central and east china，and plays an important role in the railway network in China．The alignment of leading Nanping—Sanming—Longyan Railway into Longyan region directly influences the transportation and economic developments of Longyan region．Based on the analysis and research on the construction cost，t}le organization of railway transportation，the coordination of it’s construction and the convenience of passenger travel，a reasonable scheme is proposed for leading the railway into Longyan region．
Research conclusions:There are two optional schemes for leading Nanping—Sanming—Longya．n railway into Longyan region．One is to lead the railway into Longyan region at Longyan Station where the centralized works have to be done．The other one is to leading the railway into Longyan region at Tieshanyang Station where the auxiliary works have to be done．Based on the analyses of thees two schemes from the aspects of the construction cost，the organization of railway transportation，the construction coordination and the convenience to the passenger travel，it is decided to adopte the second scheme．The determination of scheme of leading high—speed railway into one area should not only meet the requirements of urban development planning，railway transport demands and saving the construction investment，but also should consider the convenience to the passenger travel．
