摘要
采用遥感和地理信息系统技术,通过对青藏铁路唐古拉山口至拉萨段铁路沿线景观进行分类和制图以及对铁路修建前后景观指数的计算,分析了铁路修建前后景观格局的变化。结果表明铁路建设工程对沿线小范围的景观格局影响较大,对沿线较大范围的景观格局影响较小。
With the aid of the technology of remote sensing(RS)and geographic information system(GIS)the landscapes in the section from Tanggula Mountain Pass to Lhasa City of the Qinghai-Tibet Railway were classified and charted and changes in the landscape pattern before and after the railway construction were analyzed.The results indicated that the impact of the railway construction on the landscape pattern is more serious in the small range alongside the line.
