摘    要:运用景观生态学方法和Arc/Info软件,研究1995年至2000年兰州至格尔木铁路沿线的区域土地利用和景观格局变化,分析交通干线(公路和铁路)的影响程度与范围。主要结果如下:(1)东线土地利用和景观格局没有发生显著变化,西线土地利用和景观格局变化较大;(2)东线缓冲带土地利用程度综合指数没有显著变化,西线缓冲带土地利用程度综合指数明显升高。缓冲带综合土地利用动态度的变化反映了交通干线的轴向影响规律;兰州至西宁铁路对土地利用变化的显著影响范围是5km,青藏铁路对土地利用变化的显著影响范围是7km;(3)9个城市缓冲带的土地利用变化分析表明:城市扩展主要发生在1km缓冲带内。

关 键 词:高原  交通干线  土地利用  景观特征值  青藏铁路

Abstract: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.
Keywords:land use  diagnostic value of landscape  Lanzhou-Xizang Railway
