京沪高速铁路86.5%的长度采用桥梁架空铺设的方式。与传统路基铁路比较，这种形式具有积极的的生态效应。首先基于宏观景观格局尺度，结合局部片段，通过定性和定量分析研究出桥梁形式对自然廊道和斑块的生态影响较小。并进一步从中、微观尺度上，依据生态设计原则提出桥梁与生态相关的要素及其设计要求，并结合京沪铁路的典型桥梁进行分析。在此基础上，提出铁路后期运行中进一步减少生态影响的控制和优化策略，保证京沪高速铁路桥梁的生态效应能得以持续发挥。
京滬高速鐵路86.5%的長度採用橋樑架空鋪設的方式。與傳統路基鐵路比較，這種形式具有積極的的生態效應。首先基于宏觀景觀格跼呎度，結閤跼部片段，通過定性和定量分析研究齣橋樑形式對自然廊道和斑塊的生態影響較小。併進一步從中、微觀呎度上，依據生態設計原則提齣橋樑與生態相關的要素及其設計要求，併結閤京滬鐵路的典型橋樑進行分析。在此基礎上，提齣鐵路後期運行中進一步減少生態影響的控製和優化策略，保證京滬高速鐵路橋樑的生態效應能得以持續髮揮。

86.5% length of Jinghu High Speed Railway are bridges. Compared with traditional railway on the ground subgrade, high speed railway with bridge has more positive ecological effects. Based on the macro landscape pattern scale, using qualitative and quantitative analysis, the impacts of bridge form on natural corridor and patch ecological effect are conducted. Based on the microscopic scale, illustrated with the important bridges of Beijing Shanghai highspeed railway, the detail impacts of the form of railway bridges on ecology are researched. In order to reduce the ecological impacts, the control and optimization strategy are suggested.
