%X Based on digital land use data from 1995 to 2000, the l an d use and landscape pattern changes of Lanzhou-Xining route and Qingha i-Xizang route are studied on a macro-scale. The conclusions are given as follows: (1) Land use and landscape pattern along the Lanzhou-Xining Railway have not changed notably, while which along the Qinghai-Xizang Railway has changed remarkably. The land use pattern of the Qinghai-Xizang Railway and the Qinghai-Xizang Highway is just in the quick-change stage, so lan d use change will be fast in the future and built-up land will incr ease quickly. (2) The comprehensive degree of dynamic land use in the buffer zones of the Lanzhou-Xining Railway and the Qinghai-Xizang Rail way shared the same trend, embodying the corridor effect of trunk lin e upon land use change. The prominent influence range of the Lanzhou-Xining Railway is 5 km, while which of the Qinghai-Xizang is 7 km. (3) The expanding range of city was mainly confined to a 1-km buffer, o nly Lanzhou showing its expanding range in a 3-km buffer zone.
