Taking Beijing–Shanghai High-speed Railway(the section of Zhenjiangnan Station) for example,this paper applied UAV remote sensing data and GIS spatial analysis to analyze current land use types in this section,on this basis used landscape pattern indices that showed high correlation with land use changes for the quantitative analysis and evaluation of ecosystem structure in the study area and also landscape pattern after the construction of high-speed railway.The results showed that UAV images performed well in the evaluation of railway landscape ecological environment,landscape structure and features represented by the selected landscape pattern indices in this paper were applicable,and capable of ensuring scientific evaluation of ecological environmental impact;the overall landscape pattern of the Zhenjiangnan Station section(Beijing–Shanghai High-speed Railway) after completion was moderate,and local ecosystem was damaged,thus scientific and reasonable ecological planning was required to design and change landscape structure.
